Ok this seems weird....
There is a map with some keys named field.0.type, field.1.type etc (don't ask reasoning, I was given this:)
There is also fieldCount as a map property so I know how many of the annoying field.X.type keys there are.
What I need to do now is loop over the count and get out the value of the keys (field.1.type, etc). So what I intially have is:
<c:forEach begin="0" end="${fieldCount - 1}" var="fieldNum">
<c:set var='theField'
value='${metaProps["field."+fieldNum+".type"]}'/>
...When doing the above I get the error...
javax.servlet.jsp.JspException: ServletException in '/WEB-INF/jsp/associateProfile.jsp': An exception occured
trying to convert String "field." to type "java.lang.Double"
I even tried using the fn:trim tag which is supposed to return a String thinking that should work:
<c:set var='theField' value='${metaProps["field."+fn:trim(fieldNum)+".type"]}'/>
and yet same error!
I know I can get around this by setting the value in a temporary var, but there must be a way to display this in one expression?
Ideas what could be going wrong? Stupid Human Error? Thanks.
