Is it possible to do more than just simple loop index evaluation with
html-el tags?
I iterate over 2 loops:
<c:forEach var="outerMapEntry" items="${outerMap}"
varStatus="outerLoop">
<tr><td><c:out value="${outerMapEntry.key}"/></td>
<c:forEach var="innerMapEntry" items="${outerMapEntry.value}"
varStatus="innerLoop">
<td><html-el:text
property="myIndexedProperty[${innerLoop.index}]"/></td>
</c:forEach>
</tr>
</c:forEach>
However, within my inner loop, I want to calculate the index as follows:
outerLoop.Index * innerLoop.size + innerLoop.index
My questions are:
1) The following works for me,
<td><html-el:text
property="myIndexedProperty[${innerLoop.index}]"/></td>,
But if I try to do any calculations like so,
<td><html-el:text property="myIndexedProperty[${outerLoop.index} *
${innerLoop.index}]"/></td>
I get errors, saying that there is no such getter defined.
2) Surely, it should be possible to use html-el to access map entries
directly? The form I have has a Map of Maps. I need to access the inner
map values, put them in a table, allow editing / submission of those
values. It seems to be excessively convoluted to put the map values in
an arraylist, just so I can access them using indexed properties.
Thanks,
