Actions and Http Services

Hi,

i am working with the orbeon form builder 3.7.1-2(nightly build from last monday, as 3.7.1 didnt work i tried the nightly build without success) for 2 weeks now and i like it very much.

Now with the basic structure of my actual project planned i wanted to start and make my forms... The first thing i learned was that the form builder is limited to 4 columns by default. That problem i got covered
by modifying forms.xml and adapting the corresponding stylesheet.

The next problem i could not solve so far...

I have tried to load values from a restful httpservice into a selection component... :

<!-- END COPY PASTE EXRACT FROM FORM BUILDER SOURCE EDITOR -->

When i hit the 'TEST'-Button in the httpservice-'designer' i get an xml-string containing exactly the data i want to show, so orbeon does get the data but it does not fill the data into the selection (this time i tried single-select-trees, doesn't work with dropdowns too).

Heres the screenshots of the httpservice and the action:





From what i could gather from the Orbeon Wiki that should be how to do it right but it seems i do miss something.

If anyone would have an idea about what i am doing wrong, any help would be much appreciated. Thx in advance.


Best regards,

Ingo
