HTML_QuickForm_Livesearch and Groups

Hello, i've tried to use the Liveserch Elemement with a group object. I have a not defined number ob elements inside the group and want do use the liveserch element for more than one element. Fist i realized that the elementId in the options Array has to be different on each element, even if it is inside a group object. This adds another problem, because the elementId is also used to define the function which has to be called. I've tried to modify the code, so that there will be always the same callback function called for the liveseach. But i did not get it work. Has anyone used the livesearch element with groups and can help me out? Sven
