When opening a TS record in TCEforms (list module f.e.) and indenting lines with tab, these indentations are "gone" (visually) in t3editor.

When indenting with tab in t3editor, tabs are converted to two spaces when opening the TS record in TCEforms again.

Found that behavior in FF3.5

I can confirm that. Tabs seem to be converted to spaces even for lines that haven't been touched, which is quite unexpected I would day...

The Problem ist, that the CodeMirror converts tabs into spaces. It does for a reason, because handling "tabs" seems not to work out in a editable iframe.

CodeMirror2 addresses this issue, but it not stable or feature complete yet.
