VE showing components inherited from JPanel? [message #144610]

Hi,

I'll try to list all of the relevant information here. Please let me
know if I've missed anything. I'm not sure if I can actually post the
code, although, if necessary, I could probably recreate a sanitized
version of it.

I have a component that inherits from JPanel, that I'm trying to add a
JButton to using VE. This panel uses a GridBagLayout, and contains 3
components that also inherit from JPanel.

The original design of the top panel was done using VE (I'm 99% sure),
but now the panel shows up in the VE blank (doesn't show a grid at all).

Is there anything special that needs to be done to have the child panels
draw properly in VE? If I run the Java code, it all looks perfect (the
way I remember it showing up in VE before).

I've been trying a few things to try to get it to render (based on other
posts I've found). One important question from that: is there a
particular order that things need to be in? Right now the initialize()
function is ordered:

this.setSize
this.setLayout
<create gridbagconstraints>
this.add(getComponent1, gridbagconstraint1)
this.add(getComponent2, gridbagconstraint2)
this.add(getComponent3, gridbagconstraint3)

And I may have mucked with that ordering in my futile attempt to get
this to render :)

Here's the versions I'm using:

Eclipse SDK
Version: 3.2.0
Build id: M20060629-1905

EMF: 3.0.0v20060918_M

GEF: 3.2.0.v20060626

Visual Editor: 1.2.0.v20060518_RC1
Visual Editor Common Data Editor: 1.2.0.v20060918_M
Visual Editor for Java user Guide: 1.2.0.v20060824_M
Visual Editor for Java Core: 1.2.1.v20060918_M
Visual Editor for Java Foundation Classes: 1.2.1.v20060918_M
Visual Editor PropertySheet: 1.2.0.v20060824_M
Visual Editor for Standard Widget Toolkit: 1.2.1.v20060918_M

There's an exception in the .log file that I think might be relevant:

!ENTRY org.eclipse.ve.java.core 4 0 2008-04-21 11:10:28.231

This sounds a lot like Bugzilla entry #162669
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=162669), but there is no
workaround posted. Mine differs a bit though, in that it is only one
particular window that is doing it.
