[TYPO3-dev] ExtDirect failure with new Extension Manager

[Taras Sajuk]

Hi Steffen,

here are some further details:

The error is occuring on the current versions of Chrome, Firefox and IE.
BTW I just experienced a couple tab crashes in IE while being in the
Extension Manager.

The PHP log has two entries on error:

> PHP Fatal error:  Cannot use object of type stdClass as array in
> /usr/local/typo3/typo3_src-4.6.0/typo3/sysext/em/classes/connection/class.tx_em_connection_extdirectserver.php
> on line 297
> PHP Fatal error:  Cannot use object of type stdClass as array in
> /usr/local/typo3/typo3_src-4.6.0/typo3/sysext/em/classes/connection/class.tx_em_connection_extdirectserver.php
> on line 297

this is where the ExtDirect message is routed to. Basically the server
expects the parameters/values array in data but gets the empty object
crated by {}.

The error is shown for every extension which has a configuration or
database update offered on the EM tab

The present installation is v 4.6.0 but the errors did show up even before
using the new EM in 4.5.6. But with 4.5.x the old EM still was an option.

I would be happy to look further into the JavaScript code. But I don't see
how to get firebug started to intercept the generation of the post data.
How does the submit button fire up the ExtJS code? But even if this would
somehow work out I just have a compressed version of the ExtJS ...

It looks like the bug is crawlig around for a while:

   - There is an unanswered post on the TYPO3-German list:
   http://lists.typo3.org/pipermail/typo3-german/2011-April/077364.html which
   points to the unresolved Bug #25170
<http://forge.typo3.org/issues/25170>on forge.
   - The thread on typo3.net
   http://www.typo3.net/forum/beitraege/sonstiges-1/104869/ stops witout
   resolution.
   - Some people here
   http://webdesign-forum.net/Thread-Kann-htmlArea-RTE-nicht-aktualisieren even
   had the brain dead idea to "solve" the problem with a patch in the sysext
   code.
