I don't know about this one. Maybe someone more guru-like will step up with an answer 8-)
I'm not quite sure why EL doesn't like this but I think it's because the List class is not a javabean - presumably EL looks for getSize() rather than the actual size(), but that doesn't explain why it's complaining about an integer.

I need to get the size (as an int) of a java.util.List I have. The following doesn't work....
<c:out value="Size = ${browseForm.map.colInfoList.size}"/>
It gives me the following exception...
ServletException in:/jsp/browseQueueBody.jsp] An error occurred while evaluating custom action attribute "value" with value "Size = ${browseForm.map.colInfoList.size}": The "." operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer. (null)'
Does anyone know how I could get the size of the List?
