I get the following stacktrace when attempting to set the mark in a source file. This is a Copliot4Eclipse bug. I couldn’t find anywhere but this discussion forum to report the bug.

java.lang.ClassCastException: class org.eclipse.jface.text.MarkSelection cannot be cast to class org.eclipse.jface.text.ITextSelection (org.eclipse.jface.text.MarkSelection and org.eclipse.jface.text.ITextSelection are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @2387f552)
        at com.genuitec.copilot4eclipse.CopilotEditSession.handleSelectionEvent(Unknown Source)
        at com.genuitec.copilot4eclipse.CopilotEditSession$1.selectionChanged(Unknown Source)

Hi,

Thank you for trying CoPilot and reporting this bug.
I ran few tests with adding book mark in the editor and could not replicate the problem.
Can you please clarify how you are setting the mark? If possible, please attach a screenshot to help us get a visual.
Also share the Eclipse Version and distribution details.

Apologies for inconvenience caused.

“Setting the mark” means typing <CTRL>-space in the java file (emacs keybinding mode). It marks the position in the text so you can then select a region with the keyboard.

You can see what the bug has to be from the stacktrace snippet I sent. It’s in genuitec code: com.genuitec.copilot4eclipse.CopilotEditSession.handleSelectionEvent

and in that code you’re casting an org.eclipse.jface.text.MarkSelection to org.eclipse.jface.text.ITextSelection

which is not a valid cast since MarkSelection is not in the type hierarchy for ITextSelection.

The type hierarchy for MarkSelection is ISelection -> IMarkSelection -> MarkSelection
ITextSelection splits off further up the tree: ISelection -> ITextSelection

See: https://help.eclipse.org/latest/nftopic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/jface/viewers/ISelection.html

Hope that helps!

Great. FYI: the same bug is tickled if I type <CTRL>-s (incremental find). I guess that also sets the mark.

[wayne]

Again thx. Submitted a fix and should be in next release.
