FCK.SetData() causes editor to become temporarily non-focusable in IE7.

[Martin Kou]

This bug was originally reported by Mathias-S in our IRC channel. To reproduce the bug:

1. Add the following HTML code to sample11_frame.html right after the submit button's HTML code.

   <script type="text/javascript"><!--
   function SetContents()
   {
   	// Get the editor instance that we want to interact with.
   	var oEditor = FCKeditorAPI.GetInstance('FCKeditor_1') ;
   
   	// Set the editor contents (replace the actual one).
   	oEditor.SetData( 'This is the <b>new content<\/b> I want in the editor.' ) ;
   }
   //-->
   </script>
   <input type="button" value="Set Editor Contents" onclick="SetContents();" />
   

2. Open sample11.html in IE7.
3. Type some random characters into FCKeditor 1.
4. Select the just added characters with some of the previously existing text in FCKeditor 1.
5. Click on the empty space between FCKeditor 1 and FCKeditor 2.
6. Click "Set Editor Contents".
7. Try to put the focus back on FCKeditor 1 by clicking it - it doesn't work. If it does, refresh the page and try again.

According to Mathias-S's original report, the bug can be reproduced in IE6 as well. But I wasn't able to do that in IE6.

Oops... wrong ticket.

The patch seems to work (at least from my understanding of the bug, although it's hard to notice it), but I think that whenever SetData is called, the stored selection should be reset, it can't be safely restored back because those nodes no longer exist, so I would add a call to FCKSelection.Release() in FCK.SetData() like the call to FCKTempBin.Reset();

[Alfonso Martínez de Lizarrondo]

Sorry, retesting to verify if #2496 works or not I've found that this patch does break at least that situation and it forces the insertion at the start of the content again.

To verify apply first #2496 and verify that the paste dialogs work correctly, then apply this patch (clear cache) and test again. For me it does fail.

[Martin Kou]

Looks like there's no other way then. I'm adding a FCK.Selection.Release() to FCK.SetData() as suggested and it solves both this bug and #2496.
