the typo3 experience

had to write a custom extension for typo3. no prior experience with it. had a few problems e.g. with caching

 <input type="hidden" name="no_cache" value="1">

... adding this to the form seems to help ...
as does having a submit button like that:

 name="'.$this->prefixId.'[submit_button]"

...
sometimes unchanged extension didnt show up at all ...
seems to help to add a table even if it isn't needed and link it to the extension in kickstart .
oh yeah ... and for some reason POST stuff in the piVars only got addressed sequentially at some point ... just threw out all the [] name stuff and accessed via $_POST the php way
