    <p>I am writing eclipse plugin. I've got MultiPageEditor in which i've got 5 pages. On first page there is an editor which extends GraphicalEditor(geEx), on second there are 2(logicInputEditor, logicOutputEditor) GroovyEditor's org.codehaus.groovy.eclipse.editor.GroovyEditor). geEx is working with one file(e.g. first.qwe) and logicEditors are working with 2 other files(in.groovy, out.groovy). In geEx there is a code:</p> <pre><code> @Override public void commandStackChanged(EventObject event) { firePropertyChange(IEditorPart.PROP_DIRTY); super.commandStackChanged(event); } </code></pre> <p>When I edit file first.qwe MultiPageEditor know that something has been modified and marks it and allow to save file - everything is fine.</p> <p>I add listeners to GrooveEditors:</p> <pre><code> logicInputEditor.addPropertyListener(new IPropertyListener() { @Override public void propertyChanged(Object source, int propId) { if (propId == IEditorPart.PROP_DIRTY){ firePropertyChange(IEditorPart.PROP_DIRTY); } } }); </code></pre> <p>I can't override commandStackChanged function, because GrooveEditor doesn't implement CommandStackListener.</p> <p>Each time I edit something in one of GroovyEditors, the MultiPageEditor is changing its state to dirty - that's what i wanted, but also exception is printed on console. So - it's working as i want, but throwing and catching exception each time user type someting in editor is slow and generally bad. </p> <p>The message is:</p> <pre><code>Problem trying to determine

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
