Re: [ve-dev] How to debug override xml?

[Rich Kulp <richkulp@xxxxxxxxxx>]

Hi,

If there are no errors, then it is possible
it is not finding your override file. Any xml syntax errors would of been
logged.

Try debugging the following spots:

1) BeanInfoClassAdapter.ExtensionDocApplies.run(String
overridePath). Put a breakpoint in here and change the breakpoint properties
to stop when overrideFile.equals("FormLayout.override"). From
there you can see if it ever loads your file.

If it loads your file then try debuggin
at:

2) VisualUtilities.getLayoutPolicyFactory(EClassifier,
EditDomain) and see if and when your FormLayout class comes in as an EClassifier
and trace through and see why it doesn't find your override.

Subject	[ve-dev] How to debug override xml?

Debugging XML: flying over dark water, at midnight, under
completely overcast sky with no moon, last instrument reading was 30 degrees
down elevation before all power lost, cannot tell if eyes are open.

Implementing a custom layout manager.  Have the LayoutManager.override
working given that the layout manager is now listed in the VE layout customizer.
 Selection results in code generation of a no arg constructor of my
layout manager using a default coding pattern:

private JPanel getJPanel() {

if
(jPanel
== null)
{ 
jPanel
= new
JPanel(); 
jPanel.setLayout(new
FormLayout()); 
jPanel.add(getJButton(),
null);

}

return
jPanel;

}

Added a FormLayout.override,
but cannot tell figure out why it is not working, which is presumed none
of the breakpoints in my FormLayoutPolicyFactory.java, including one on
the first line of the constructor, are ever reached.

No console or log error messages in the EclipseWorkspace or runtime-EclipseApplication
.metadata/.log files.

How to debug?  How do I tell which xml statement is failing because
it is invalid or what in the chain from extension-point -> FormLayout.override
-> FormLayoutPolicyFactory.java is not being found.

Presuming that this problem is surmountable:

1) Am I required to provide a beaninfo for the layout manager?
2) What controls/specifies the pattern of code generation?  Is it
all done with BeanUtilities.createJavaObject,
etc or is there a template somewhere that defines the pattern.  I
will need to generate using a pattern similar to GridLayout:

private JPanel getJPanel() {

if
(jPanel
== null)
{ 
String colSpec = "..."; 
String rowSpec = "...";

FormLayout formLayout
= new FormLayout(colSpec, rowSpec); 
CellConstraints cc =
new CellConstraints(); 
jPanel
= new
JPanel(); 
jPanel.setLayout(formLayout);

jPanel.add(getJButton1(),
cc.xy(1,1));
// add at col 1, row 1

jPanel.add(getJButton2(),
cc.xy(2,1));
// add at col 2, row 1 
}

return
jPanel;

}
