problem

Pressing ctrl-c to copy content can produce the following JS errors, depending where the cursor is:

• node.childNodes is undefined
• Uncaught TypeError: Cannot read property 'length' of undefined

Both in rangy lib.

See attached screenshots.

solution

If ctrl-c is pressed and cursor is in or cell is selected in:

• language resource match panel: print a message to double click on the segment to overtake it
• language resource concordance panel: copy content of selected cell
• selection is empty in an input field or on a extjs control item (row head): copy nothing / do nothing
