Nested Tags Question
Hi,
I have some thing like -
<c:choose>
<c:when test='${registrationForm.dobYear !=
""}'>
<date:complete monthName="dobMonth"
dayName="dobDay" yearName="dobYear" dayValue="<c:out
value='${registrationForm.dobDay}'/>"
monthValue="<c:out
value='${registrationForm.dobMonth}'/>"
yearValue="<c:out
value='${registrationForm.dobYear}'/>" />
</c:when>
<c:otherwise>
<date:complete monthName="dobMonth"
dayName="dobDay" yearName="dobYear" />
</c:otherwise>
</c:choose>
However, the value that is being passed to the
date:complete tag for dayValue, monthValue, and
yearValue are the exact strings eg. <c:out
value='${registrationForm.dobMonth}'/>. If i print the
same thing out on the page it prints the value. It
looks pretty obvious to me that nesting the tags is
blocking interpretation of the inner tag. Any
suggestions please?
Thanks,
-kalyan

For JSP 1.2 and earlier, <rtexprvalue> means an attribute can take an expression
of the form <%= ... %> as its value. It's not until JSP 2.0 that the container
provides the same level of built-in support for EL expressions. If you want to
use EL expressions for attribute values in your own tags you have to handle it
yourself and set <rtexprvalue> to false. See the following for an example:

Guys - Thanks for the response but in the below
example,
<c:set var="aux"><thevaluetag/></c:set>
<othertag attibute="${aux}"/>
the othertag is literally taking the String "${aux}"
instead of its value. I do have
<rtexprvalue>true</rtexprvalue> for that particular
attribute set. Any thoughts?
Thanks

Yes. In that case, "aux" will be a page-scoped variable whose value is the
result of trimming the string produced by the <thevaluetag/> tag.

Would it work?
<c:set var="aux"><thevaluetag/></c:set>
<othertag attibute="${aux}"/>

You can't use one tag as an attribute value for another tag...
