[TYPO3-dev] Extending existing controller

[Charles Brunet]

Hello,

How can I add either a new Controller or a new action to an existing
controller, to an existing plugin provided by another extension?


I know I could simply subclass the existing controller, and replace the
value of the class name in config.tx_extbase.objects. However, doing like
this, only one extension can extend an existing plugin.


To be more specific, I want to extend the news extension by adding a new
action to it. I also use the roq_newsevent extension, that already extends
the news extension. However, I don't like the was it does it, because it
replaces the Domain and Controller classes by subclassing them, preventing
me to do the same. I could simply subclass the Controller provided by
row_newsevent, but I'd like my extension to work with or without
roq_newsevent.


It is easy to add a new action to the interface using the provided
configuration variable:

$GLOBALS['TYPO3_CONF_VARS']['EXT']['news']['switchableControllerActions']['newItems']['News->byFobar']
= 'A fobar action';

In that array, 'News' is the name of the Controller. I could provide my own
Controller, but in that case, how would it find it in the right php file,
without disturbing other configured controllers?


This is where I am stuck now. Is there a mechanism of extbase I am not
aware that could help me, or is it a limitation of the framework?


Thank you for your help,
