Hi Dennis and Tim,

thanks for your replies and excuse me for the late reply, i was very 
busy with this project. I managed to get mvc_extjs working. I think the 
error was from a wrong implementation in my extension. Addiotionaly i 
had to create a new page type in my TS to disable the standard 
rendering of my page for the mvc_extjs calls. Therefore i added the 
type GET-paremter to 
Tx_MvcExtjs_ViewHelpers_ExtDirectProviderViewHelper which works fine 
for me, but it should be configurable.

The mvc_extjs extension is realy a great extension to work with 
ext.direct. Also i have to things i would change, maybe when i'm ready 
with the project and have some time.

1. The controller actions aren't usable for normal views, i.e. fluid 
because the method $this->view->setConfiguration() doesn't exist in 
fluid.

2. The possibility to use viewhelpers in combination with a basic 
template for the actions would be nice, this also would fix problem 1. 
A viewhelper would be nice i.e. for image manipulation. Currently i 
have a very ugly workaround in my controller where i resize the image 
manualy by copying the viewhelper logic.

Kevin
