Custom Developed Editor only contains "ERROR" if used to open external file [message #257574]

I am working on the CMakeEd project (cmakeed.sourceforge.net) and I
have a bug report that basically says if I try to open an external
cmake file (one NOT already in a project) then I get a blank editor
window opened up with just the word "ERROR" in it.

As a test I opened a .java file and it opened just fine. I would like
the same functionality for my editor but can not quite seem to figure
out what I am either supposed to extend in the xml (extension point) or
implement in my editor. I currently have the following in a
CMakeDocumentProvider class:

protected IDocument createDocument(final Object element) throws CoreException
{
final IDocument document = super.createDocument(element);
if (document != null) {
final IDocumentPartitioner partitioner =
new FastPartitioner(new CMakePartitionScanner(),
CMakePartitionScanner.CONTENT_TYPES);
partitioner.connect(document);
document.setDocumentPartitioner(partitioner);
}
return document;
}

When a cmake file is opened from with a project the 'document' variable
is NOT null. If an external CMake file is opened then 'document' is
null.

I tried looking for the javaeditor example but can not seem to find the
source code for the examples. Alternately where would the full source
for the built in java editor be located?

Any help or just pointing me in the right direction would be great.

Thanks

Hi Mike,

To find the source code you are after, please take a look at
http://wiki.eclipse.org/index.php/CVS_Howto

Connect to "dev.eclipse.org" as user "anonymous" with Repository path
"/cvsroot/eclipse".

There you can find the javaeditor example under project
"org.eclipse.ui.examples.javaeditor"

and the jdt java editor source code in project
"org.eclipse.jdt.ui" package "org.eclipse.jdt.internal.ui.javaeditor"

Let your document provider extend
org.eclipse.ui.editors.text.TextFileDocumentProvider. In addition you
might need to setup the parent document provider. See
org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitDocume ntProvider.CompilationUnitDocumentProvider()
for details.
