Description

« Hide

This maybe similar to IDEADEV-14856, but I'm not sure this is the same user case.

1. Create a form with Form or Grid layout. Put three components in a row.
2. Select at least two components near each other. Ctrl+Click on rightest component. Drag to copy.
3. Drop the group into area "before the 1st column". Get trace.
If to click on leftest component in step 2, bug does not occur.

The symmetric case happens with pasting before the 1st row.

BTW, undo history is corrupted after that. Immediate Undo returns the form to 1-2 steps before the drag. E.g. some editing of component's text is lost.
