Guys,
I need to evaluate an EL expression that contains variables of variable
names. From the archives, it seems the way to do this is by accessing them
through the implicit objects pageScope, requestScope etc.
http://marc.theaimsgroup.com/?l=taglibs-user&m=105730468108706&w=2
However, I couldn't really get this to work. I want the value of:
<c:out value="${pageResults.sortHistory.roles.sortColumn}"/>
Which works fine, pageResults is in the request scope. So I try:
<c:set var='OBJ' value='roles'/>
<c:out value='${requestScope["pageResults.sortHistory." + OBJ +
".sortColumn"]}'/>
This gives an error "An exception occured trying to convert String
"pageResults.sortHistory." to type "java.lang.Double" (null)". So I guess my
syntax here is wrong? Strangely, even when I try:
<c:out value='${requestScope["pageResults.sortHistory.roles.sortColumn"]}'/>
This doesn't actually return anything? What am I doing wrong?
Thanks for your help!
Cheers
Mark C
