Reported through user group. Dev tried to add an error associated with a groups id, but the error is not displaying. Issue is the group did not have a header and the errors were not bubbling up. We need to add a test case for this as well.

I have been trying to display an error message during the addlinevalidation. Here is my barebone performAddLineValidation() method in the maintainableImpl class and the snippet of my xml configuration. By setting the breakpoint inside performAddLineValidation(), I saw it was called but just no error message was printed to the screen. No exceptions were thrown either.
Could you guys shed some light on this weird issue? Really appreciate it!

protected boolean performAddLineValidation(View view, CollectionGroup collectionGroup, Object model, Object addLine)
