How to initialize a new page for embedded data in Constellation
I have a field of type embedded data + list of records.
I can configure a view to show it as a table with a modal dialog to add new records.
How to initialize a newly created page?
More details at point 5 in below link
In the Theme-cosmos, when I define a DT with name pyDefault it used to run before creating a new page but I dont see it working in constellation.

@SateeshB6784the pyDefault data transform does work, however, this only fires in Constellation when it has a reason to do so.
If you add a calculation (declare expression) to the create form of the embedded data object, then it will run your pyDefault on creation of the record. This is the only way I know of, unless you split creation over multiple steps/assignments (not ideal).

@cheom - Thank you for your response Marc.
Your comments confirm the actual issue we are facing in 24.1 version
When we configured an embedded data to display as a table and add/edit as table rows --> it runs pyDefault and row gets initialised correctly.
When we configured an embedded data to display as a table and add/edit as Modal --> it does NOT RUN runs pyDefault
I did not fully understood your mention of calculation (declare expression) to the create form. If we declare a field as a calculation, then it will become read-only right? In my situation, I just want to populate it with a default value so that user can modify to his or her choice.
I think the product should have the same consistency of running pyDefault weather its table row or modal.
Also, in your modal approach, your field is getting initialised not because of pyDefault but because of declare expression. Did you actually see pyDefault in tracer in your modal appraoch? Thank you

@SateeshB6784 @SateeshB6784 it works better as a table though, you don't need an on change event, just telling the table to be visible > when > always, is a enough to trigger this. See these images.
