In reviewing the HTML code for forms with multiple multicolumncombo boxes I notice there are multiple versions of the CCHighLightSelected type functions. Each of these has conditions within the routine based on the name of each control. I have not observed any bugs but am not sure if each object will be addressing each routine correctly. I suspect there should only be a single copy of these routines with parameters being passed identifying the calling object. Would you check if there is a possible pontential bug here.
There currently are no known issues with the IWMultiColumnComboBox control. However this is a good suggestion and we'll investigate if the duplicate routines can be removed in a future version.
The problem outlined above definitely results in failure of forms with multiple lookups. I had to make the following source code change to get it to work. We still get multiple copies of the CScript for some reason?
