What happened?

Encountered in both the Hop-Web 2.11.0 GUI (container running on a RHEL 9.4 host) , aswell as in Hop-GUI 2.11.0 for Windows.
CTRL+SPACE+ENTER in a text field that allows choosing HOP variables (such as ${PROJECT_HOME}) throws an error message.
In case of Hop-Web GUI, the application crashes, in case of local Windows installation you can click the error away and continue working.

Steps to reproduce:

• open default project
• create a pipeline
• add a text file output transform
• edit the text file output transform
• select the string "file" in the text input field "Filename"
• hit CTRL+SPACE+ENTER (no mouse clicks in between)
  (I know: before the ENTER a mouse click to choose a variable in the dropdown would be the correct way to continue)

In Hop Web GUI, this leads to "Server Error The application terminated unexpectedly."
In Windows GUI, this leads to "An error occurred executing action RunTimeException: Error executing method : editTransform in... Root cause: SWTException: Widget is disposed." but you can continue working
