Wrapping controls into hboxes or other containers requires setting dataContainer explicitly

Support
#1

Is it intentional that when you wrap some controls into an hbox or other container, you then have to set their dataContainer properties explicitly? (Or am I missing another reason things don’t work before I do that?)

I wrapped some controls into an hbox, went in to test the screen, and said fields were blank even though the data was there in the DB. To troubleshoot, I tried setting the dataContainer of these fields, and voila, it all then worked as expected. When controls are added to a screen, this property is blank but everything works fine… once wrapped into a container of some sort, they no longer work.

Hi,

I suppose that you’re talking about the Form component, if so then it’s intended behavior. When you wrap components into hbox/vbox/etc. It means that you provide a custom layout and it’s hard to infer what field is supposed to present an entity attribute, so it’s completely up to you.

Hmm, I still feel like it should inherit the dc up the nesting hierarchy.

Just putting a, for example, textField onto a screen using the designer, you have:

layout -> form -> column -> textField

That textField doesn’t need its dataContainer set; it inherits it up the tree.

But say you wrap 2 textFields in an hbox, then you have:

layout -> form -> column -> hbox -> textField textField

I still feel like the dc should be inferrred from up the tree.

It’s no big deal to set it manually; it just doesn’t seem like that one additional nesting layer should halt the inheritance of the dc.
