[TYPO3-dev] controlling alt_doc.php via JavaScript / RTE Help needed

[Steffen Ritter]

Hey folks,
I'm currently on a litte backendmodule where I'm integrating alt_doc.php 
record editing via an Iframe.
I'm currently issueing save and close as

tceFormFrame.document.editform.closeDoc.value=-1;
tceFormFrame.document.editform.doSave.value=1;
tceFormFrame.document.editform.submit();

which works fine so far for all field-Types except the RTE.
All changes in RTE are discarded.

What do I have to do to geht the "rte saved" too? The Buttons in 
docheader don't do anything else...

Thanks for hints.
regards

Steffen
