Hi,

This is a new feature request, to be specific for the <logic:present> tag

I am developing a JSP which may or may not be passed request (1 or more) 
parameters. As such at the start of my JSP, I have:

<bean:parameter id="param1" name="ParamName" multiple=�true� />

If there are parameters in the request �param1� above will be set to a 
java.lang.String[]

But if there are no parameters in the request object, this raises a 
JSPException. So had to enclose this within a 
   <jsp:present paramter=�ParamName�> tag

But here-in I had to specify the parameter name that is expected. (the problem 
I face here is my JSP does not know before hand what parameter to expect)

So suggest an attribute like �multiple� for the 
   <logic:present parameter=�xxxx� multiple="true"> tag

Which will return true, if they are 1 or more parameters in the request object. 
(better that checking for the existence of a particular parameter in the 
request)

This could be extended to other logic tags where-ever appropriate.
