Hi,
I am trying to open an IJavaElement (created from an actual .java file) programatically by using:
IProject project = ... // get a project from workspace.
IFile file = project.getFile("<ClassName>.java");
ICompilationUnit javaElement = (ICompilationUnit) JavaCore.create(file);
javaElement.open(null);
However, for the last line of the code, I get the following exception:
org.osgi.framework.BundleException: The activator com.kivancmuslu.deneme.Activator for bundle com.kivancmuslu.deneme is invalid

I think this happens because the thread I am invoking the method is not a GUI thread, am I correct?
As a related and different question, do you know what changes internally for a IFile (or IJavaElement) when it is actively selected and opened in the page? If I were to find it and could do the same without actually openning the file, I think it would also work.
Thanks, regards,

Actually it is in under the src/ directory. I think the problem is something else.

Hi Dani,
Thank you for your question. Sorry that I wasn't clear.
What I really want to do is that to perform a Change object (created using QuickFixProcessor).
However, the problem is that, I figured out, the change is not applied if the particular file that it will modify (i.e., change.getModifiedElement()) is not open in the Eclipse's page view and selected at least one. I know that it sounds strange, however I have tried it many times with many debugging and if I don't open the file in Eclipse's workbench page, then when I invoke change.perform() nothing happens (I don't get an error, no notification). On the other hand if the file is open and selected, then when I say change.perform() the change is applied correctly.
I have to do the whole process (creating the change and applying it automatically, i.e., I cannot open the file that would change manually). Therefore, I need to one of the following before invoking change.perform()
1- Actually open the file on the workbench page (so that it is also selected) and run the change. I have tried this inside the constructor of the plugin, it works, however the actual thread that should do this is a background thread and since it is not a GUI thread, Eclipse API throws exception when I try to open an editor for the file to change (using page.openEditor()).
2- Figure out what does opening the file int eh workbench page changes internally for an IFile or CompilationUnit. I guess that if I can mimic the same thing without actually opening the file in the page, then the change will also be applied correctly.
I might be missing something or if anything does not make sense please point it, I will try to explain in detail. Again, thank you for your interest,
Regards,

This is an internal class which you should not use and for which there's
no support. You should create your own Change(Operation).

Take a look at the apply(...) methods on the proposal.

Hi Dani,
I had written a quite long reply normally, however for some reason the system didn't accept it and it is gone.
In summary (please ask me if something is not clear, I would explain it in more detail), I have looked at ChangeCorrectionProposal.apply(...). It seems that it is getting active page (which is got through the active window). I am not sure if this is my problem but, I am sure that when you try to get active window using a non-UI thread, then it returns null (it is even documented to return null in this case). So in my version, I definitely cannot get the active page (I get null), because I need to apply the changes using a background thread (daemon).
So, my question is: When I do change.perform(...) it doesn't change anything in the target file. Is this due to the fact that I am invoking it from a non-UI thread, and this is not permitted? If so, I might need to completely change my design, if not, I will look more into it.
I ask this, because other than that what is done in ChagneCorrectionProposal.apply(...) seems very alike to the pattern proposed in Change.java documentation to apply the changes.
* Here is a code snippet that can be used to execute a change:
* <pre>
* Change change= createChange();
* try {
* change.initializeValidationData(pm);
*
* ....
*
* if (!change.isEnabled())
* return;
* RefactoringStatus valid= change.isValid(new SubProgressMonitor(pm, 1));
* if (valid.hasFatalError())
* return;
* Change undo= change.perform(new SubProgressMonitor(pm, 1));
* if (undo != null) {
* undo.initializeValidationData(new SubProgressMonitor(pm, 1));
* // do something with the undo object
* }
* } finally {
* change.dispose();
* }
I also use a minor modified version of this above code to perform the changes. As I said however, when I invoke change.perform(...) (which returns normally), the target file does not change.
However, if I do the same using a UI thread (i.e., from plug-in's constructor for testing), then it again does not change the target file (performing the change does not change the target file).
However, if I do the same using a UI thread, and if I open the file that is supposed to change using page.openEditor(...) (since this is a UI thread, I can get the active page), now the change is applied correctly and the target file is updated accordingly.
Since I don't know the internal of these whole classes and the interaction between them, this seems pretty weird to me (i.e., it is like that I need to open the file inside an editor to apply a change object on it). Again, I might be missing something.
Thanks a lot for the help, any further guidance is greatly appreciated.
Regards,
|

Why not just post into the UI thread?
