#connector_text_filter - switch to JSON Data

Hi,

is there a way to switch the #connector_text_filter function to update its list based on JSON data?

Some info about my project.
html + dhtmlx + perl script generating JSON grid data works fine. (No, I don’t use the CPAN connector and I don’t plan to.)

The page runs and I can see my JSON data in the dhtmlx-grid without any problems.

Now the problem:
When I enter something in the text filter line my perl script receives the parameted and generates a valid JSON code as an answer. I found out that the text_filter seems to require XML data instead of JSON.
Is there a way to switch the #connector_text_filter to the JSON format?
(I don’t want to implement another XML functions for the text filter function only.)
