Hi,
I've been using visual editor for a while now and it's been working fine. However , starting today I noticed that I am getting errors in the error log with vague descriptions that I'm not sure how to fix. My visual component is a simple window with a text area and a few buttons. The errors happen when I'm editing the code. Here are two of them and I'm hoping someone can help.
1. Exception Thrown
Plugin - org.eclipse.ve. java.core
java.lang.NullPointerException
at org.eclipse.ve.internal.java.codegen.util.CodeGenUtil.create Instance(CodeGenUtil.java:103)
at org.eclipse.ve.internal.java.codegen.util.CodeGenUtil.create Instance(CodeGenUtil.java:116)
at org.eclipse.ve.internal.java.codegen.model.BeanPart.createEO bject(BeanPart.java:809)
2. Exception Thrown
plugin - org.eclipse.ve. java.core
java.lang.ArrayIndexOutOfBoundsException: -1
at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:5 14)
at org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObjectF orURIFragmentRootSegment(ResourceImpl.java:642)
at org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObject( ResourceImpl.java:692)
Thanks in advance

If the VE is working otherwise, I guess it is ok.

I thought that might be the issue because Eclipse opened with an error today so I did run a -clean on it when I opened it again but that didn't fix this error. I'm not sure what the issue could be.

Hi,
Not -clean. That clears only the plugin configurations. It doesn't clear
cached metadata. You need to use the procedure I outlined to clear the
cached metadata.
Actually -clean should rarely be needed except if you are just putting
plugins directly into the eclipse configuration without using the
install manager or the dropins folder.

Thanks , I tried that but it didn't seem to fix it. I think I may know what the problem is. I have modified the section where the visual editor creates the jTable and the visual editor doesn't like this.
Visual Editor likes this:
String[] columnNames = {"Column1", "Column2"};
Vector<String> columnNamesV = new Vector<String>(Arrays.asList(columnNames));
jTable = new JTable(getRowData(),columnNamesV);
My modified code which it doesn't like:
String[] columnNames = {"Column1", "Column2"};
Vector<String> columnNamesV = new Vector<String>(Arrays.asList(columnNames));
jTable = new JTable(getRowData(),columnNamesV){
...custom table code here including creating a rendered to modify the color of the rows
};
Any ideas ?

Yeah, I could see that being a problem. The VE needs to be able to
instantiate a visual component. A non-static inner class can't be
instantiated.

I'm also getting errors in another class that doesn't have any tables and for the most part it's got the same code that VE inserted.
The error is :
java.lang.NullPointerException
at org.eclipse.ve.internal.java.codegen.util.CodeGenUtil.create Instance(CodeGenUtil.java:103)
at org.eclipse.ve.internal.java.codegen.util.CodeGenUtil.create Instance(CodeGenUtil.java:116)
at org.eclipse.ve.internal.java.codegen.model.BeanPart.createEO bject(BeanPart.java:809)
Is this something I should be worried about ? Could my install of VE be corrupted ?
Any suggestions ?

I think I may have found the issue. I removed GUI components one by one from the frame to see when I could add a space in the source and watch the GUI sync and generate an error. When I removed the jTextArea I no longer get the error when the GUI syncs. I'm not sure why this is happening but at least I am getting somewhere.

I'm not sure why either but there is a workaround you can use to have VE
ignore the line. It's kind of kludgy. We never got to put in an
annotation that would tell VE to ignore something when I was working on
VE. :-(
if(false)
;
else
jTextArea.getDocument().addDocumentListener(new MyDocumentListener());
This will work because VE is designed to ignore the else block of an if
statement.

A little bit of grammar problem there. It is not that we never put in
code to have something ignored only when I was working on VE! And so by
corollary when I'm not working on the VE it wouldn't ignore something. :-)

Are there any issues with just leaving my code as is and let VE generate those errors ?
My concern with adding the code as described is it will make the code harder to read and also what happens if in a future release the issue is fixed ?
