An insertion of any kind of INPUT element is not undoable.

[Aleksey Onopriyenko]

Steps to reproduce (for checkboxes, radiobuttons, etc).

1. Load sample01.html
2. Set the cursor at the end of text.
3. Press Checkbox button on the toolbar. A dialog window will appear.
4. Fill the fields in and press Ok button.

A checkbox has been inserted but Undo button is disabled.

This can be fixed pretty easy by adding the following line in Ok function of the appropriate dialog window (see dialog/fck_table.html for example).

oEditor.FCKUndo.SaveUndoStep() ;

But I wonder if this behaviour is intentional.

[Frederico Caldeira Knabben]

Those kinds of actions must certainly be undoable.

Aleksey, with your fix, you are calling SaveUndoStep only when inserting new objects in the editor, but not when simply making changes to already existing things. I believe both actions must be undoable, even if in some cases the undo will not bring a visual effect (when changing a field name, for example). I think that call should be in the first line inside the Ok().

Is there any motivation for your choice?

[Aleksey Onopriyenko]

You are right. The both actions must be undoable.
