JSP expression not resolving correctly in <html:textarea> tag

I have an iterate process set up to loop through the values in an ArrayList.

I then want the value of the loop index (specified by the "indexId" attribute) to be used to get an indexed parameter from my ActionForm.

Here's a snippet:

CODE

<logic:iterate id="field" name="Template0Form" property="questions" indexId="idx">
   <div id="q<%=idx+1%>" class="showMe">
      Question <%= idx+1 %>:<br/>
      <html:textarea style="margin-left:10px;" property="questionsIndexed[<%= idx %>]" rows="3" cols="50"></html:textarea>
   </div>
</logic:iterate>

Here's the problem:

the "<html:textarea>" tag resolves before the jsp expression "<%= idx %>" which results in an error stating that I don't have a property in my ActionForm called "questionsIndexed[<%= idx %>]"

What I want is for the <%= idx %> to resolve to it's integer value before the <html:textarea> tag is resolved.

The two lines above the <html:textarea> tag have the <%= idx+1 %> resolve correctly.

Any Idea where I'm going wrong?

How is the the questionsIndexed defined in your ActionForm?

CODE


String questionsIndexed[];  //Like this?

typedef map<GiantX,gold, less<std::shortestpathtogold> > AwesomeMap;

It's coded as

CODE

String [] questions;

public String[] getQuestionsIndexed(int index) {
   return questions[index];
}

The getter method matches the property field in the <html:textarea> tag.  That is done so that I can change the underlying collection without having to change to contract with the JSP.

But the problem is not with the ActionForm, it is with the JSP not resolving the expression within the <%=  %> tags at all.

It's as if the <html:textarea... tag is being handled first and that code takes "<%=...%> as a literal instead of a JSP expression.
