I have the same question. i wanted to pass some form value that the user selects to allow it
to be used in the produceDataset class. I used
<cewolf:producer id="chartViews" >
<cewolf:param name="aa" value='<%=(
String)the value %>'/>
</cewolf:producer>
and in the 'produceDataset(Map params)' function I tried to get it as:
String aa = (String) params.get("aa");
But it just prints the value as null.
How can I pass values to this function. someone please help!!
