Hi
I previously posted on the same problem but can't find an answer.
I'd need to see a code snippet that does what the following javadox
promises : creating an ICompilationUnit on an not-yet-existing one
my attempts so far fail - to me it seems I need to create the resource
BEFORE I commit.
TIA,
Edo
--------------
package org.eclipse.jdt.core;
public interface ICompilationUnit ...
/**
....
* Since 2.1, a working copy can be created on a not-yet existing
compilation
* unit. In particular, such a working copy can then be committed in
order to create
* the corresponding compilation unit.
*/
void commitWorkingCopy(boolean force, IProgressMonitor monitor) throws
JavaModelException;

Thanks Jerome!
can you confirm that there is currently no way to open an editor on such
a compilation unit ?
if you think it would be reasonable to implement such a request, I'll
enter it into bugzilla
My rationale is that my plugin provides an editor for a 'domain object'
which has some details implemented by java classes.
As long as the editor is dirty, ie manipulating a domain object in
memory, I would be happy to keep the ICompilationUnits in memory as well,
and commit (or discard them) all when the editor is saved (or closed
without saving, respectively).

I'm not in the editor business, but I would expect to be able to open an
editor on such a compilation unit.
What makes you say that it is not possible ? Do you get any exception when
attempting to open an editor on such a compilation unit ?

The exception is ... "File does not exist" (surprise :-)
here is attached an action that you can declare in an action set and try
I'm submitting the issue to bugzilla
