MuleESB. How to stop for each loop? - json

Good day, collagues.
Give me the cue, pls.
In one my case for JSON parsing i am using FOR EACH component with Choice inside him.
Like this:
After http request i have in the paylaod some JSON result, which represents of some collection. Foreach treats every item from collection and compute it's properties with condition in Choice component.
I want to stop the loop when condition in Choice was found. I don't want to compare all items of result collection.
I tried to change the variable 'counter' inside the Fore each loop. But it is not working.
May be anybody has found the way?

You may not be able to do this using a for-each. But you could always have an expression/groovy script to do this loop and breaking based on your condition. Please refer this: Is there a break statement in Mule <foreach>

Reading RawRequest JSON parameter value in SoapUI changes its value

I'm trying to transfer parameter from RawRequest using SoapUI but when reading it, value changes.
The parameter is request ID (which is unique for every test), it is requested by every test case from Custom Properties, where it is stored as follows:
${=((System.currentTimeMillis().toString()).subSequence(4, (System.currentTimeMillis().toString()).length())).replaceFirst("0", "")}
Above generates number like this for example:17879164.
The problem starts, when I'm trying to transfer it using either in build in feature or Groovy script. Both read parameter incorrectly:
Following is how the parameter presents in RawRequest window:
This is how it is read in Transfer window in SoapUI:
And finally, how it is read by Groovy script:
Can any one explain, why this value despite being shown in SoapUI RawRequest window as 17879164 is then read as 17879178 using two different methods?
I think the clue might be, that when I'm using "flat number" as reqId and not the generated one, both methods work fine and return correct number. But in this case when it is RawRequest, I understand that it is set once and for all, so what is show in the window and what is being read, should be the same.
What you are seeing is a "feature" in SoapUI. Your transfer step will transfer the code, which will then get evaluated again, resulting in a different value.
What you need to do is:
Create a test case property.
Set the property from test case setup script to a value. So in your case, something like testCase.setPropertyValue("your_property", ((System.currentTimeMillis().toString()).subSequence(4, (System.currentTimeMillis().toString()).length())).replaceFirst("0", ""))
Anywhere in your test refer to the test case property ${#TestCase#your_property}... which is a fixed value at this point, so will be always the same.

webMethods loop over Document list

I am creating a flow service, and inside it, I inserted another flow, which has document list as output and contains 5 string fields.
Problem is that I can't loop over that document list, whatever I put in Input array (getPropertyOutput, getPropertyOutput[0]) is ignored (in debug mode, it just skips the loop step). Same happening with the sequence step...
Any help would be appreciated
Let say I want to loop over list of Strings I have simple flow service:
In first step (MAP) I created the list...
As second step, there are properties for LOOP important:
Input array: /list
But here is the trick, notice the icon in MAP step - there is String list, but in pipeline for debugLog step, there is list variable as String - it is the current String variable from list (I agree, very bad practice of SAG).
With Document list it will be very the same...
I'd recommend to the the remap as first step in loop, for example:
Warning:
LOOP is a very very slow construct in flow, so one shouldn't be using this at all. Alternative is to use Java for looping (yes, ugly again, but LOOP performance will kick you to a butt, sooner or later).

Using $skip with the SharePoint 2013 REST API

Forgive me, I'm very new to using REST.
Currently I'm using SP2013 Odata (_api/web/lists/getbytitle('<list_name>')/items?) to get the contents of a list. The list has 199 items in it so I need to call it twice and each time ask for a different set of items. I figured I could do this by calling:
_api/web/lists/getbytitle('<list_name>')/items?$skip=100&$top=100
each time changing however many I need to skip. The problem is this only ever returns the first 100 items. Is there something I'm doing wrong or is $skip broken in the OData service?
Is there a better way to iterate through REST calls, assuming this way doesn't work or isn't practical?
I'm using the JSon protocol with the Accept Header equaling application/json;odata=verbose
I suppose the $top=100 isn't really necessary
Edit: I've looked it up more and, I'm not entirely sure of the terms here, but using $skip works fine if you're using the method introduced with SharePoint 2010, i.e., _vti_bin/ListData.svc/<list_name>?$skip=100
Actually, funny enough, the old way doesn't set a 100 item limit on returns. So skip isn't even necessary. But, if you'd like to only return a certain segment of data, you'd have to do something like:
_vti_bin/ListData.svc/<list_name>?$skip=x&$top=(x+y)
where each time through the loop you would have something like x+=y
You can either use the old method which I described above, or check out my answer below for an explanation of how to do this using SP2013 OData
Alright, I've figured it out. $skip isn't a command which is meant to be used at the items? level. It works only at the lists? level. But, there's a way to do this, actually much easier than what I wanted to do.
If you just want all the data
In the returned data, assuming the list you are calling holds more than 100 items, there will be a __next at d/__next (assuming you are using json). This __next (it is a double underscorce, keep that in mind. I had a few problems at first because I was trying to get d/_next which never returned anything) is the right URL to get the next set of items. __next will only ever be a value if there is another set of items available to get.
I ended up creating a RequestURL variable which was initially set to to original request, but was changed to d/__next at the end of the loop. Then the loop went and checked if the RequestURL was not empty before going inside the loop.
Forgive my lack of code, I'm using SharePoint Designer 2013 to make this, and the syntax isn't horribly descriptive.
If you'd only like a small set of data
There's probably a few situations where you would only want x amount of rows from your list each time you go through the loop and that's real easy to do as well.
if you just add a $top=x parameter to your request, the __next URL that comes back with the response will give you the next x rows from your list. Eventually when there are no rows left to return __next won't be returned with the response.
Don't forget that in order to use __next you need to have a
$skiptoken=Paged=TRUE
in the url as well.

How to enumerate the keys and values of a record in AppleScript

When I use AppleScript to get the properties of an object, a record is returned.
tell application "iPhoto"
properties of album 1
end tell
==> {id:6.442450942E+9, url:"", name:"Events", class:album, type:smart album, parent:missing value, children:{}}
How can I iterate over the key/value pairs of the returned record so that I don't have to know exactly what keys are in the record?
To clarify the question, I need to enumerate the keys and values because I'd like to write a generic AppleScript routine to convert records and lists into JSON which can then be output by the script.
I know it's an old Q but there are possibilities to access the keys and the values now (10.9+). In 10.9 you need to use Scripting libraries to make this run, in 10.10 you can use the code right inside the Script Editor:
use framework "Foundation"
set testRecord to {a:"aaa", b:"bbb", c:"ccc"}
set objCDictionary to current application's NSDictionary's dictionaryWithDictionary:testRecord
set allKeys to objCDictionary's allKeys()
repeat with theKey in allKeys
log theKey as text
log (objCDictionary's valueForKey:theKey) as text
end repeat
This is no hack or workaround. It just uses the "new" ability to access Objective-C-Objects from AppleScript.
Found this Q during searching for other topics and couldn't resist to answer ;-)
Update to deliver JSON functionality:
Of course we can dive deeper into the Foundation classes and use the NSJSONSerialization object:
use framework "Foundation"
set testRecord to {a:"aaa", b:"bbb", c:"ccc"}
set objCDictionary to current application's NSDictionary's dictionaryWithDictionary:testRecord
set {jsonDictionary, anError} to current application's NSJSONSerialization's dataWithJSONObject:objCDictionary options:(current application's NSJSONWritingPrettyPrinted) |error|:(reference)
if jsonDictionary is missing value then
log "An error occured: " & anError as text
else
log (current application's NSString's alloc()'s initWithData:jsonDictionary encoding:(current application's NSUTF8StringEncoding)) as text
end if
Have fun, Michael / Hamburg
If you just want to iterate through the values of the record, you could do something like this:
tell application "iPhoto"
repeat with value in (properties of album 1) as list
log value
end repeat
end tell
But it's not very clear to me what you really want to achieve.
Basically, what AtomicToothbrush and foo said. AppleScript records are more like C structs, with a known list of labels, than like an associative array, with arbitrary keys, and there is no (decent) in-language way to introspect the labels on a record. (And even if there were, you’d still have the problem of applying them to get values.)
In most cases, the answer is “use an associative array library instead.” However, you’re specifically interested in the labels from a properties value, which means we need a hack. The usual one is to force an error using the record, and then parse the error message, something like this:
set x to {a:1, b:2}
try
myRecord as string
on error message e
-- e will be the string “Can’t make {a:1, b:2} into type string”
end
Parsing this, and especially parsing this while allowing for non-English locales, is left as an exercise for the reader.
ShooTerKo's answer is incredibly helpful to me.
I'll bring up another possibility I'm surprised I didn't see anyone else mention, though. I have to go between AppleScript and JSON a lot in my scripts, and if you can install software on the computers that need to run the script, then I highly recommend JSONHelper to basically make the whole problem go away:

jQuery tmpl: handling null/undefined elements

I have a data structure returned by a web service. It's a few levels deep, and could have null instead of the expected object. Which results in some ugly code to check.
<td>{{if FulfilledBy}}${FulfilledBy.Name}{{/if}}</td>
I can't change the output of the service, but I'd rather not need to check if FulfilledBy exists prior to access the .Name property.
Is there a better way to write this? I would have preferred something like
<td>${(FulfilledBy || {}).Name}</td>
but it doesn't work either.
According to docs, you can use expressions within ${}. Have you tried ${FulfilledBy? FulfilledBy.Name: 'no name'}?
