Re: OCM:Supporting nested properties for the FilterImpl
At present, this not possible but I think it should be nice to implement
it.
See the issue http://issues.apache.org/jira/browse/JCR-878 (see the latest
point in this issue). We can split this issue into smaller ones .

a node or a property.
Eg.
Foo{
String id;
ListBar myBar;
}
Bar{
String id;
String name;
}
Filter(Foo.class); [Not exactly but you get the idea!]
Filter.addEqualsTo(myBar[].name, CA's Pub Pub);
Ocm.getObjects(Filter) , fetches all the Foos with a nested property
name=CA's Pub
Any thoughts? Is it possible with the current API?,

RE: OCM:Supporting nested properties for the FilterImpl
The Mapping file gives a good handle on guessing what the equivalent
node or property name is. I think the current mapping file has all the
information needed to do an OGNL like traversing of the Nodes. Will try
out a testcase to understand the challenges.
