i'm trying to create custom dataprocessor to allow to format editor's data to be compatible with older forum application (DCForum+ 1.27). format is a little bit similar to bbcode. also my dataprocessor is based on older bbcode plugin - source here: http://www.51aspx.com/CodeFile/YetAnotherForum195/YetAnotherForum.NET/editors/ckeditor/plugins/bbcode/plugin.js.html or here http://text.md/ckeditor-bbcode-plugin/.
if i use default ckeditor's dataprocessor i get the same output for all browsers (IE, FF, chrome).
when i enable my custom dataprocessor which has no formatting (so far) in toDataFormat function (only writer definition as per htmldataprocessor) i have the same output after switching to Source mode in IE & chrome:
<p>line 1</p> <p>line 2 E<br /> line 3 SE</p> <p>line 4 E</p>
