I know how to use input widget in Slate but I have a use case where I need to create several inputs from an array. Maybe one, maybe more, let's say around 10 or 15. Is that possible to create a input and to catch the user entry just by using an HTML widget.
One other way to say shoud be: I would like to have a table of 1 to 15 rows with one column dedicated to an input area. Number of row depend of the source data, so I want that the input is created dynamically. Is it possible in foundry-slate ?
Best regards
You can't do this in a plain HTML widget - the dependency graph can't read state from arbitrary HTML input elements.
There are a couple other options here; the one that most directly works they way you would like it to in your question, would be to use the Code Sandbox widget, which effectively let's you build your own widget and wire it up to the Slate dependency graph for interaction with the rest of the app. You can use a 3rd-party library, assuming you have the license, to do something more advanced (you can search your Foundry instance for some examples in the Slate Reference Examples) or simply use HTML and Javascript to build the widget as you would in normal web development as you have access to the DOM and JQuery when working in the Sandbox.
Slightly more in-line with how Slate might expect you to build this functionality, you can use a single input widget, but toggle what you do with the associated input based on other state, for example what row the user has selected. This, in combination with a button that stores the input into a Variable with a click event, can be used to let users build up a "bag" of edits, that you can then apply with Actions (or you can apply them immediately - all depends on the workflow). You'll find some examples of that pattern in the "Events" folder in the Slate Reference Examples.
Thinking a bit more expansively, if you model your data in the ontology, you can set up an editable table pattern in Workshop and have a quite straightforward experience once you have the right Action and Object Type configuration. You'll find the documentation on this on your Foundry instance at https://www.palantir.com/docs/foundry/workshop/widgets-object-table/#inline-edits-or-cell-level-writeback and an example in the Flight Alert Inbox example application.

I currently have a app that manages projects. The user sees a list of projects and can select one. They can should (it would be nice) be able to click a run button and have another app open. The parameters stored in the project they selected are populated into the second application. The issue I am having is firing the second application. runApp generates the following.
ui code line:
actionButton("RunProj", "Run"),
Warning in run(timeoutMs) :
Unhandled error in observer: Key / already in use
observeEvent(input$RunProj)
I would like to trigger the second app and pass in the location of the project directory I have looked at parseQueryString and still trying to figure out a way to include that. Maybe via a redirect?
Any suggests would be much appreciated.

I'm not 100% sure if I understand your intention correctly but here is a few things I think you may want to think about.
In one project, if you want to run a few kinds of analyses, you may want to try navbarPage
If there are many different types of analyses, you may want to try shinydashboard
If you know the link to each app and you really want to add those "run" buttons, you can add a button manually in ui.R. I think you can write some codes in server.r to generate the link based on your database.
tags$a(href="the link to your apps", class= "btn btn-default", "Run App")
I am making a code completion system for a code editor, and i would like to show a tooltip for every parameter containing its reference data. I would like to emulate the code completion from Eclipse, so i was wondering if the API reference is available in code, or if i have to manually import it using the file system or something like that.
You could reflect the current class in question with flash.utils.describeType
This will return a xml with informations about methods, properties and so on.
This can be very heavy. If you use it all the time, try to use a caching system. The Flex framework has a class for it mx.utils.DescribeTypeCache
I'm developing a component using joomla 3.0. I'm trying to add forms in my component. I saw that joomla has the JHTML class for adding forms in backend.
what is the recommendation for creating forms in frontend. should I use JHTML or clean html markup ? and where can I find docs for that class.
JForm
JModelForm
JControllerForm
Forms which save data in the databas in Joomla 1.6 + mainly use the JForm package which manages forms (xml or xml strings), fields (the actual fields) and rules (validation).
The normal way simple way to manage it is to extend JModelForm and JControllerForm. If you look in the core you'll see these extended in places you might not expect such as the single contact view but basically that's because those classes provide the basic set up you need to manage a form on any part of your page even if the rest of it has nothing to do with forms.
Alternatively you can always create a new JForm object.
If you have a models folder usually you would have a forms folder and then if needed fields and rules folders. THe latter two contain any custom fields or rules you may need for your extension. These will be found by default when building a form in your extension but if you want them from somewhere else you would need to use addFieldPath or addRulePath or addFormPath as needed in you form xml.
Jform provides a standard set of fields and rules as well as a standard list of filters. Rules means validation while filters will change the saved values. You can also use any filter available in JFilterInput.
If you give a field the same name as a field in the current table object the data will automatically be saved in that field. if you use a fields tag with an name that matches a field by default the fields listed inside the tag will be saves as a JSON string within that field.
That's pretty much the basics, though there is a lot more.
One important thing for me is that if you use JForm the default filtering is very good and you selectively allow html etc so by default it is very secure.
I'm making a game and I an in-game editor that is able to create entities on the fly (rather than hard coding them). I'm using a component-aggregation model, so my entities are nothing but a list of components.
What would be the best way to obtain or generate a list of components? I really don't want to have to manually add entries for all possible components in some giant registerAllComponents() method or something.
I was thinking maybe somehow with reflection via either the knowledge that all components inherit from the base Component class, or possibly via custom metatags but I haven't been able to find ways to get a list of all classes that derive from a class or all classes that have custom metatags.
What sort of options am I left with?
Thanks.
For a project I did once, we used a ruby script to generate an AS file containing references to all classes in a certain package (ensuring that they were included in the compilation). It's really easy considering that flash only allows classes with the same name as the file it's in, so no parsing of actual code needed.
It would be trivial to also make that add an entry to a dictionary (or something similar), for a factory class to use later.
I believe it's possible to have a program execute before compilation (at least in flashdevelop), so it would not add any manual work.
Edit: I added a basic FlashDevelop project to demonstrate. It requires that you have ruby installed.

Unfortunately, there is no proper way of getting all loaded classes or anything like that in the Flash API right now. So finding all sub-classes of Component is out, inspecting all classes for a specific meta tag is out as well.
A while ago I did run into a class/function that inspected the SWF's own bytecode upon loading to retrieve all contained classes. That's the only option for this kind of thing. See this link and the bottom of my post.
So, you're left with having to specify a list of component classes to pick from.
One overly complicated/unfeasible option that comes to mind is creating an external tool that searches your source folders, parses AS3 code and determines all sub-classes of Component, finally producing a list in some XML file. But that's not a task for the faint-hearted...
You can probably think of a bunch of manual solutions yourself, but one approach is to keep an accessible Array or Vector.<Class> somewhere, for example:
public static const COMPONENT_LIST:Vector.<Class> = Vector.<Class>( [
CollisionComponent,
VisualComponent,
StatsComponent,
...
...
] );
One advantage over keeping a list of String names, for example, would be that the component classes are guaranteed to be compiled into your SWF.
If the classes aren't explicitly referenced anywhere else in your code, they are not compiled. This might occur for a simple component which you only update() once per frame or so, and is only specified by a string in some XML file.
To clarify: You could use the code in the link above to get a list of the names of all loaded classes, then use getDefinitionByName(className) for each of them, followed by a call to describeType(classObj) to obtain an XML description of each type. Then, parsing that for the type's super-types, you could determine if it extends Component. I personally would just hardcode a list instead; it feels too messy to me to inspect all loaded classes on startup, but it's up to you.
I have Mysql and Zope talking to each other nicely.
I can insert values in, and even view one record from the databse and have it show up in the form fields(not that cool really).
I have just been following tutorials, but now I need to search the Database and display the results.
I have been fiddling with this for a while but I haven't gotten far.
I know that using a Zope Page template we can call the Zsql method and show the results with TAL, but I need to some how using a script and a redirect form the search form pass the search data.
Can anyone help we get started?
Can anyone show me a way to do it with formgen and a custom script adapter?
Go into your ZMI, and add a "Z Search Interface" object in the same folder as your ZSQL method. Your ZSQL methods should show as "searchable objects". Select the ZSQL method you want, fill in the rest of the fields, and it will generate form and display page templates. Then modify the templates to taste.
