indexing in tag 'iterate'
Hi
I need a form representing a two-dimensional array of input fields.
Can anybody tell me what the appropriate solution in Struts 1.0 looks like?
Despite numerous attempts to solve this with Struts, I did not succeed. My
attempted solution (in fact, one of them) looks like that
('account', 'amount' and 'remark' are indexed properties of the Bean
represented by 'report'):
...
table
tr
thAccount/ththAmount/ththRemark/th
/tr
bean:define id=report type=ReportForm toScope=session name=select
property=report scope=session/
html:form name=report type=ReportForm scope=session action=log.do
logic:iterate name=report property=entries id=entry indexId
=entryId
tr
tdhtml:text name=report property=account[entryId]//td
tdhtml:text name=report property=amount[entryId]//td
tdhtml:text name=report property=remark[entryId]//td
/tr
/logic:iterate
trtd colspan=3center
html:submit
bean:message key=button.submit/
/html:submit
/td/tr
/html:form
/table
This causes the exception:
java.lang.IllegalArgumentException: Invalid indexed property
'account[entryId]'

If I replace the index variable 'entryId' by a literal number (see below),
this works so far (though it is not 'meaningful', ); thus the environment
(beans etc.) seems to be OK.
...
table
tr
thAccount/ththAmount/ththRemark/th
/tr
bean:define id=report type=ReportForm toScope=session name=select
property=report scope=session/
html:form name=report type=ReportForm scope=session action=log.do
logic:iterate name=report property=entries id=entry indexId
=entryId
tr
tdhtml:text name=report property=account[2]//td
tdhtml:text name=report property=amount[2]//td
tdhtml:text name=report property=remark[2]//td
/tr
/logic:iterate
trtd colspan=3center
html:submit
bean:message key=button.submit/
/html:submit
/td/tr
/html:form
/table
I suppose there must be a solution in Struts for this standard problem. How
does it look like?
Thanks if you can bring me on the right track.

Re: indexing in tag 'iterate'
This is mostly a guess, but in the iterate tag's description, it states that
the indexID must be a pagescope bean. I think you must do something like:
%
int entryId=0;
pageContext.setAttribute(entryId, entryId, PageContext.PAGE_SCOPE);
%
And this will initialize an entryId int and place it into the page scope.
Hope this helps...

Re: indexing in tag 'iterate'
I got this completely working in a test, so if you need more help then to
put entryId as an Integer equalling 0, let me know. Oh, and if you couldn't
figure this out, when you use it as an index, it will come out as an Integer
value, and you'll need to say something like:
tdhtml:text name=report property=account[entryId.intValue()]//td
