Subject: Length of collection using EL?
Does anyone know how to get the length of a collection using the EL? I am
trying to do one of the tests below. Note that "children" is a List.
<c:if test="${component.parentDao.children.length > 1}">
<!-- stuff here -->
</c:if>
or
<c:if test="${component.parentDao.children.size > 1}">
<!-- stuff here -->
</c:if>
And get this error:
javax.servlet.jsp.JspException: An error occurred while evaluating custom
action attribute "test" with value "${component.parentDao.children.length >
1}": 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.
Thanks!
Matt
