When I use (1) in my xhtml, I get an error as in (2). How can I access the size of an array in my bean?
(1) A List of objects of a custom class type, accessed through the following h:outputText in a rich:column in a rich:subTable in a rich:dataTable:
<h:outputText value="Info: #{f.filemask.size()}" />
(2)

Any help greatly appreciated. I cannot seem to find references to using methods like this but this reference reported it working fine
“Normal” EL does not support this. Possibilities:
getFileMaskSize())and access#{f.fileMaskSize}.
