As I have grid of checkboxes I am currently trying to use embedded
maps as arguments in Struts 2, for example using

@Element( value = HashMap.class )
public Map<Integer, Map<Integer, Boolean>> getTestMap() {
return testMap;
}
Using
/testAction.action?testMap[1][2]=true
Although it places the value in the right place, it is always
ognl.noConversionPossible
Hi Matt,
I haven't tried this myself, but I'd take the following steps to try
to isolate it:
1. instantiate the empty map of maps yourself prior to the params
getting set. Erasure may be preventing OGNL from instantiating the
inner map because it can't determine the type.
2. I'd try quoting those numbers so it's unambiguous that it's
addressing an entry and not an index. Shouldn't matter though, but I
don't trust it.
