Hi,
I tried to use a JComboBox as a custom cell editor and experienced some problems. The combo box works until the default text editor is used for the first time. After the first text edit, the text editor starts throwing IllegalComponentStateExceptions.
The problem seems to be that the GridView never resets the currentTextEditor reference to null. So even when processing an edit event for the ComboBox, there is a currentTextEditor reference set from another/previous cell edit.
In endEdit currentEditor is set to null, but currentTextEditor is not...
Another problem in endEdit might be

if (newValue instanceof String)
  lastIO.setEditedText(newText);
 

because newValue != newText.

The attached file contains a small example.

Hi,

New jar here should fix that -
https://mindfusion.eu/_temp/JPack_editor.zip

If you build from source code, our fix is replacing this line in beginEdit -

if (currentEditor instanceof JTextComponent)
    currentTextEditor = (JTextComponent)currentEditor; 

with this one -

currentTextEditor = Helper.as(currentEditor, JTextComponent.class); 

(that accounts for incorrectly translated currentTextEditor = currentEditor as TextBoxBase assignment from our original C# code, which also nulls currentTextEditor when using a custom editor).

Hi,

Value from your custom editor is set correctly on next line (cell.setData...newValue). The newText assignment seems would be incorrect if custom editors return strings, which should be fixed here -

If you build the jar from source code, our fix is in attached diff, setting newText before validations code so it's used there too. The diff contains one other fix we've found in our C# EndEdit, for comparing values from custom editors.
