Hi, I have a plug-in with a tree of objects, and when one node in the tree
is selected, some data in the object is shown as an editor at the
IWorkbenchPage. The problem is that it always open a new page instead of
checking if an object already is open and then only make that page as the
active.
The code used is shown below:
IWorkbenchWindow window =
PlatformUI.getWorkbench().getActiveWorkbenchWindow();
IStorage storage = new StringStorage(value);
IStorageEditorInput input = new StringInput(storage);
IWorkbenchPage page = window.getActivePage();
if(page != null) {
if(page.findEditor(input) == null || (!value.equals(""))){
try {
page.openEditor(input, "org.eclipse.ui.DefaultTextEditor");
}
catch (PartInitException pie) {pie.printStackTrace();}
} else {
page.activate(page.findEditor(input));
}
}
/regards Frasse

Thanks for the help it works fine now. I implemented hashCode() function.
