Hello,

Does EMF Forms support showing a value from another entity in a view within a table control?

From the example project:
Show a TableControl in the UsersGroup view that list the tasks from the Task entity.

Can anyone point me to an example?

Thank you!

Hi,

I am not sure, if I understand your question correctly. You can show entities, which are referenced in a table. There is no reference from UserGroup to Task, though. But you could show the "Users" of a user group in a table.
Does that make sense?

Best regards,
Jonas

Hi,

Maybe I was not clear with my question, I'm sorry for that.

I was wondering if it's possible to access a 'hierarchy' of references.

Indeed, there is no reference from UserGroup to Task, but is there any way in which is possible to 'navigate' from UserGroup to Task through the users reference (having in mind that a User has a reference to tasks)?

Thank you!

To be even more explicit, I was thinking at the following example:
A TableControl in which the first column is UserGroup:name, the second column is the User:firstname and the third column is the Task:name.

Kind Regards,

Alexandra

Hi,

so in general, you can extend those tables very easily to show any kind of data you want. I am still not sure, if I understand your case, though. The first column is UserGroup:name. In the second, you want to display User:name, but there can be an arbitrary number of users per user group. The example confuses me even more, if you want to display Task:name in the third columns, because there is an arbitrary number of tasks per user. Maybe I still not get what you want, sorry for that! :-)

Best regards,
Jonas
