It seems there is a confirmed bug in the WAudio setting the ID using setId and using a WComboBox,
but even after I commented that out, I still have a bug with the WComboBox working after binding the WAudio widget. I created a thread for this on the Forum, not sure if everyone monitors it or not, so here is an update: http://redmine.emweb.be/boards/1/topics/9495 Do you have any idea what might cause this problem, so I can figure out how to troubleshoot it, I am not getting any warnings or error messages now and its not crashing, but the Session seems to be crashed on the client end, seems like something is messing up the output to the browser. The WidgetFunction does work great, thanks again for that, you can change the URL to test the line-editor http://wittywizard.org:8080/ww/audio/usetemplate/t/usetemplatedata/4/usewidgetfun/0/useWraper/f you can create a 100 of them with no problem, but when I use it for Audio http://wittywizard.org:8080/ww/audio/usetemplate/t/usetemplatedata/0/usewidgetfun/0/useWraper/f you can see the combobox stops working, there are also some other test, changing the path changes the variables used in the matrix, so it makes testing easier. By the way, do you know of a better way to parse parameters then the way I am doing it?
