I think the problem is how the NetBeans code is using its
GridBagConstraints. They re-use the same field, e.g.
GridBagConstraints constraints = new GridBagConstraints();
panel.add(component1,constraints);
constraints.gridx = 2;
panel.add(component2,constraints);
The VE parses code and currently does not deal with shared properties in
this way. It's a subtle thing that GridBagLayout does where in fact the
constraints are not shared (they are cloned by the layout manager),
because with any other piece of Java code objects are passed by
reference and changing the constraint and re-using it wouldn't be allowed.
We do have a bugzilla to deal with this kind of grid bag constraints
behavior as it is quite a common coding pattern, however in the meantime
try changing the source so that each GridBagConstraints is a new field, e.g.
GridBadConstraints constraints = new GridBagConstraints();
panel.add(component,constraints);
GridBagConstraints contstraints1 = new GridBagConstraints();
panel.add(component2,constraints1);
The key is that the single field for GridBagConstraints it not shared.
Once this change is done the VE should be able to open the source OK.
Best regards,

HiJimmy

Can you give it a try ? Just take the .java file and import it into
Eclipse and open it with the VE ? Let us know what happens, and also
can you post the file you're trying to open and we'll take a look and it
might be just a small tweak required to make it work and it'll also help
us to learn more about code styles the VE should parse.
Best regards,
Joe Winchester
