IE: table cell properties giving error undefined (table tools, onshow invalid selection) when enterMode = CKEDITOR.ENTER_BR

[svanlang]

Steps to reproduce:

Set config.enterMode = CKEDITOR.ENTER_BR; create a table. click into a single cell, use contextmenu / cell /cellproperties

The error in browser is in tabletools\plugin.js on row 14 where seletion is empty. Fired in tableCell.js onShow(line 504) were this._.editor.getSelection() gives no result.

this only happens in IE. I cannot reproduce this in firefox. tested in IE8/IE7/IE9

Only when enter mode is set to BR.

Also tested on the nightly build. Still was the case.

I can reproduce this also in 3.5.4 and 3.5.3 I cannot reproduce this in 3.5.2

True for IE7/8/9 from CKEditor 3.5.3 rev [6478].

The error from tableCell.js is:
Message: 'undefined' is null or not an object
Line: 223
Char: 13
URI: /_source/plugins/tabletools/dialogs/tableCell.js

The error in browser is in tabletools\plugin.js on row 14 where seletion is empty.

We had similar error with tabletools and line 14 #7529

IE8:

1. An error occurs when opening "Cell Properties":

   'null' is null or not an object  tabletools/plugin.js, line 14 character 3
   

   Note: in the elements path suddenly "h1" appears when dialog opens.

2. After clicking "Ok"

   'length' is null or not an object tableCell.js, line 512 character 23
   

3. Opening "Table Properties" results in:

   'null' is null or not an object table/dialogs/table.js, line 61 character 6
   

   After pressing "Ok" new table is inserted.

Affects all dialogs opening when cursor inside table cell, regression of [6698]

#4385,#5221,#6629 should be checked.

The patch looks good but this issue is no longer reproducible in latest CKEditor 3.6.2
