org.eclipse.ui.PartInitException: Unable to open editor, unknown editor ID 錯誤
Eclipse3.2M6以后,Editor在plugin.xml里注冊時，必須帶icon參數(shù)
<extension
id="gef.tutorial.step.ui.DiagramEditor">
<editor
id="gef.tutorial.step.ui.DiagramEditor"
name="Diagram Editor"
icon=""
class="gef.tutorial.step.ui.DiagramEditor"
default="false">
</editor>
</extension>
在對應(yīng)action中得run函數(shù)中打開編輯器.
IEditorInput input = new DiagramEditorInput(new Path(path));
IWorkbenchPage page = window.getActivePage();
try {
page.openEditor(input, DiagramEditor.ID, true);
} catch (PartInitException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
