If it really happens that two XCLASSes extend the same method the later on will "win".

this get's done by the XCLASS-Manager.

It rewrites the code of the extension automaticall if you "move it to the right" and makes ux_ux_
out of ux_

It also changes the XCLASS inclusion lines in the ext_localconf.php file of the moved extension so
it XCLASSes the parent class:

$TYPO3_CONF_VARS['XCLASS']['BE']['t3lib/class.t3lib_tceforms.php'] = t3lib_extMGM: ....
get's rewritten to:
$TYPO3_CONF_VARS['XCLASS']['BE']['ext/someext/class.ux_t3lib_tceforms.php'] = t3lib_extMGM: ....



PS: I didn't want to download the complete TER at this time cause it still was the old one ... now
that the new TER is finished I could download it completly and search for XCLASS extensions using grep
or something similar and do some "field tests" ...


Of course if some people report me that it works properly for some extensions (please name them) I couls
also put it into TER (until now just download it from this demo-site - directly from the EM)


greets,
Bernhard
