I have created an entity, initialized its position with an array of lat/long. That's to say, the position of an entity is changed with time.
Now, I would like to add the current position to the description of an entity, which is shown when the entity is selected.
How to do that?

I would like to set up a hyperlink from a foreign key column in the backing dataset of object type A to the respective object of type B.
Following an existing and working example, in the dataset preview, I have added a type class in the form of {{object type B id}}.{{object type B's property id}}. However, this is not giving me a link. Do I need to format this differently or are there any additional configurations required?
Further investigation revealed that in addition to the type class described in the question, this also requires a configuration change by a Palantir representative.
in Spring boot, I have an entity called Event. All the fields from the entity needs to come from user. I want that this entity should contain a field called approval status. This field doesn't need input from user but during display of that entity need that field populated from some source(from approval table) and displayed along with other fields of entity. Is there a way, I can include this field in Event class itself and specify no input or the only way is to create a wrapper class wrapping Event and approval status field?
Thanks,
#Transient is the exact thing which fulfill your use case.
Make field transient in your entity class and then set it in controller from whatever source you want to, and display it in page.

Problem Statement :
We have a table of rows with unique GUID's and also Revit 3D Modal members associated with GUID's.
I am trying to highlight exact GUID Modal member On click of a checkbox of matching GUID from table row.
Please suggest on triggering point to highlight modal member dynamically.
Please find the attached screenshot for the reference.screenshot
There are a couple of ways of finding the object with your GUID. I would recommend using the Model.getExternalIdMapping method. It will generate a dictionary mapping internal IDs ("dbIDs") to external IDs (in this case, Revit GUIDs). You can then use this map in an "inverted" way, finding a dbID for a specific GUID.
Once you know the dbID of your object inside the viewer, you can use viewer.select, viewer.isolate, or similar methods to provide visual indication.
I am doing a project on Springs and Hibernate.
I have a problem which am stating below:
I have 2 entities (District and Address) and I wanted to display a form which contains properties of both entities using form tags in jsp.,for single entity I can do this with CommandName and can retrieve the form values,but if i want to include properties from 2 tables..
How can I do this???? Kindly help me...
I usually create a model object that represents all the fields on the form. Then my model object would contain a District property and an Address property. You can then use nested property paths to access the properties of the nested object.
I am using annotations to map a basic collection of Strings to an existing entity like this. Inside the parent entity class:
#org.hibernate.annotations.CollectionOfElements
#JoinTable (name="GoalToAchieve_entry", joinColumns=#JoinColumn(name="goalToAchieve_id"))
#org.hibernate.annotations.Sort(type = org.hibernate.annotations.SortType.NATURAL)
private SortedSet<String> entries = new TreeSet<String>();
This works fine. I have a 2-column (goalToAchieve_id and element) table resulting from the join. So I was wondering, how can I add a date/time stamp (auto-generated by MySQL) to each String of the collection. So that I can display a 3rd column with a time stamp every time a new String is added to the collection? The objective is to use a collection of simple objects (Strings) and not have to create a whole new entity (with a time/date field).
Is there a recommended way to do that? I believe even if I provide a timestamp field at the jsp interface which handles the adding of new Strings to the collection, it would still be a hibernate issue, since I need the timestamp to be persisted on the db.
Thanks in advance for any help.
Kindest regards
Hibernate #CollectionOfElements can be used with more than just simple types. You can define a class which contains two fields, your String value, plus a timestamp, and annotate that class with #Embeddable. Hibernate will then persist that to the database as two separate data columns. This class doesn't represent an Entity, just a composite value-type.
The next problem is how do you generate that timestamp. You could do it in java, with the default initialised value of the field being "new Date()" (or whatever).
