Build Identifier: I20100608-0911 I am using the javascript editor (CompilationUnitEditor.class) within my RCP to edit script files - which works fine for all kinds of IFile. Now I wanted to add another IDocumentProvider to edit some JavaScript code that is generated by the RCP (and not written to any IFile). Unfortunately the editor fires up with a single line stating "error". This is how I am accessing the editor: final IEditorDescriptor editorDescriptor = PlatformUI.getWorkbench().getEditorRegistry() .getDefaultEditor("foo.js"); final IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(); final MacroEditorInput editorInput = new MacroEditorInput("//test\nvar a = 5;"); page.openEditor(editorInput, editorDescriptor.getId(), true); I tracked it down to CompilationUnitEditor.setDocumentProvider() here my registered provider is assigned to fImplicitDocumentProvider. But as there is an explicit provider too (which is of type CompilationunitDocumentProvider) my implicit provider is never used. How is it possible to edit such files? Reproducible: Always
I found a way to make this work: The editorInput used for the editor needs to implement IStorageEditorInput. here is a reference implementation: public class MacroEditorInput implements IStorageEditorInput { @Override public Object getAdapter(final Class adapter) { return null; } @Override public IPersistableElement getPersistable() { return null; } @Override public boolean exists() { return true; } @Override public IStorage getStorage() { return new IStorage() { @Override public Object getAdapter(final Class adapter) { return null; } @Override public boolean isReadOnly() { return false; } @Override public String getName() { return MacroEditorInput.this.getName(); } @Override public IPath getFullPath() { return null; } @Override public InputStream getContents() throws CoreException { return new StringBufferInputStream("this is the content for the editor"); } }; } @Override public final ImageDescriptor getImageDescriptor() { return null; } @Override public final String getName() { return "Editor with generated content"; } @Override public final String getToolTipText() { return "My editor"; } }
