[TYPO3-mvc] Loading the alt_doc.php in a backend module with ExtJS

[Mario Beiser]

Hi everybody,

after some talk with Dennis Ahrens (Thanks, Dennis :-)), I did a backend 
module based on a ExtJS-Grid. The grid just shows some data from my 
models which is caught by an jsonReader.

Now I want to implement a modal window, which enables the user to edit 
the dataset shown in the grid rows. The modal window opens by a simple 
doubleclick-event. So this works already, but I don't want to produce my 
own forms to maintain the data. Rather I want to display the forms 
produced by the tca.php.

So I'm going to load the alt_doc.php with different params into the 
modal window.
The problem I'm currently confronted with, is that in the window there 
is no rtehtmlarea: Only 'The Editor is being loaded...'

AFAIK this is caused by a frame-problem.

Some ideas, how I'm able to load the rte?

All the best,
Mario
