[Bug]: hitting OK in transforms does sometimes not apply the changes

[gmitter-ef]

Apache Hop version?

2.12.0, 2.13.0-snapshot

Java version?

OpenJDK 17

Operating system

Windows

What happened?

• choose default project
• create a new pipeline
• add a "Data grid" transform
• add a field "test" of type "String" and enter "A" as data
• rename the Data grid to e.g. "test" (not sure if renaming is actually necessary for the bug exposal!)
• save the file
• Repeat the following steps:
  ** edit the Data grid
  ** delete value "A" for field "test"
  ** hit "OK"
  ** save the file
  ** edit the Data grid
  ** enter value "A" for field "test
  ** hit "OK"
  ** save the file

At some point in time, the file does not get bold after hitting OK, and the changes you made are not applied!!!

This is a bug that applies to all kinds of transforms, and is hard to reproduce, but extremely annoying.
NOTE: this seems to have been introduced in 2.12.0., until 2.11.0 this was never experienced.

i can confirm also the behavior. i am experiencing this also at version 2.8.0. its very annoying when we are doing a lot of changes and loosing them just with a click of a button.

Hi @gmitter-ef you suggested to use DataGrig transform because you are experiencing the issue on that transform only? Can you give us a wider view if the problem? The problem you are experiencing is related with events handled by any visual component (with this term I mean any component in Hop that has a gui so for example transforms, actions and so on). That said I'm asking you about that because it could be an issue related only with the way the DataGrid component handle GUI events.

Hi @sramazzina! No, it is a problem that is NOT restricted to DataGrid transform only, I only chose DataGrid because there it was rather simple to reproduce the issue.
