Hey all, I've got a 2-layer hierarchy of data to put in through a
form, and it's getting messy. I've got a set of groups, each with a
set of questions within. Each are indexed with simple integers.
I"ve been using
<input type="radio" name="<s:property value='group' />_<s:property
value='question' />" value="1" />
And wanted to pull the values out of the request, but suddenly I've
got this bad boy:
ParametersInterceptor - [setParameters]: Unexpected Exception catched:
Error setting expression '0_0' with value '[Ljava.lang.String;@a572fc'
That should go away if you set devMode to false. Just ignore it.
How do I get ParametersInterceptor to leave it alone, or put in the
mechanics to let OGNL set the property correctly? My groups are an
ArrayList<ResponseGroup>, each with a member responses, which is an
ArrayList<Response>.
Maybe something like this (untested):
<s:iterator var='group' value='groupList' status='gs'>
<s:iterator var='question' value='#group.questionList' status='qs'>
<s:textfield name='%{#groupList[#gs.index]
.questionList[#qs.index]}'/>
(without the linebreak in the QGNL expression).
