Re: accessing multiple select params

Jim,

Thanks very much, that works just fine, e.g.:

<c:forEach items="${paramValues.foo}" var="currentValue">
  <c:out value="${currentValue}" />&nbsp;
</c:forEach>
-c

I believe you would use ${paramValues.foo}.  Although I have not tested
myself yet.  It will return a String[].

Subject: accessing multiple select params


Normally one can access a reqest parameter like this: ${param.foo}

But what should be done with the result of a multiple select? e.g.

<select name="foo" size="4" multiple>
<option value="farble">Farble warble</option>
<option value="blort">much blortiness</option>
<option value="bar">bar bar bar</option>
<option value="google">google</option>
[etc]
</select>
If I just ask for $(param.foo} in this case, all I get is the first one
the user selected. So if the user selected 'blort' and 'bar', I only get
'blort'.
If the 'foo' parameter is getting passed as an array in this case, how
does EL treat that array, does it give you a param.???? syntax for
accessing the array, or must the programmer parse it out by hand?
thanks,
