Hi.

If i try to open a Diagram File which is not located in the Workspace (Files in Workspace work fine) and get an Error:

Cannot open input element:
Reason:
Text editor does not have a document provider


I just dont have an idea where i have to fix that problem. Sad Can somebody point onto the Functions which are responsible in this case? Under that mass of generated Code i just dont find it...

Thanks a lot!

Hi,

I don't know exactly if GMF supports this, but Eclipse might do that. I didn't try open diagram files but I open xml files that are located outside eclipse:

Have a look at this static method:

IDE.openEditorOnFileStor(IWorkbenchPage, IFileStore)

The IFileStore can be created with a path, so the file doesn't have to be in the workspace:

IFileStore fileStore = EFS.getLocalFileSystem().getStore(new Path(file.getAbsolutePath()));

YOu could load your diagram file into that filestore and open the editor using the IDE api.

Hope that does the trick.

Artur

Hi.

Thanks for your hint, i will check that.

What i forgot to write... i changed the Wizard to create a new Diagram that it is also possible to create the Files outside of the Workspace. As Template i used the Wizard (public class NpgmCreationWizardNewFileCreationPage extends WizardPage) which is used if you generate the RCP Application and not the Plugin. Odd is, if i use the Wizard to create a Diagram located outside of the Workspace it works! Works means, it loads the Diagram into the Editor... but if i want to save it, the Wizard for "Save As" in the Workspace displays...

I guess somewhere are Settings which binds it somehow to a... hm "Workspace" File?

Hello Oliver,

Try using URIEditorInput and pass File uri there..

Hi Alex,

thank you for your answer! Maybe you can give me finger point to the area of code i should look for that? I get a little lost in the 40k loc of the generated app. Sad Or maybe to the documentation where a description is how the plugin saving interaction works?

Thank you very much!
Olli

Hello Oliver,

Well, you are passng EditrInput object while openning new editor from your
code.
Currently I suppose you are using FileEditorInput. I'm suggesting you using
URIEditorInput instead of File one..
The rest should be done for you in GMF-generated code.
