Hello Bastian,

thanks a lot for the explanation!

In short I wrote down these lines now whereas the first variable still 
is noted statically:

$_EXTKEY = 'some_extension_key';
$extensionName = t3lib_div::underscoredToUpperCamelCase($_EXTKEY);
$pluginName = $this->controllerContext->getRequest()->getPluginName();
$pluginSignature = strtolower($extensionName . '_' . $pluginName);
$pluginNamespace = 'tx_' . $pluginSignature;

and it works and seems being the same as

$this->data = 
$this->controllerContext->getRequest()->getContentObjectData();
$pluginNamespace = 'tx_' . $this->data['list_type'];


Sense of retrieving the $pluginNamespace by one of the above noted 
methods is to verify it with the incoming URL-parameters and devide 
variables from the current controller from other controllers / plugins.
Furthermore I change the variables from the current controller as 
mentioned in other posts from the default notation to the following one 
that they include the CObjUid:

$pluginNamespace['CObjUid'][$Action]

This I realized in an own viewHelper and it works so far now.

Now I still have some questions:
1) is the prefix for the pluginNamespace always 'tx_'?
2) Are the results of both above noted methods always the same?
3) Has one method (dis-)advantages?

And finally I'd appreciate a tip where and how to write a modul that 
reads the changed URLs in my extension.


Best Regards,
David
