Andy Jefferson commented on JDO-652:
------------------------------------
If you get problems then you need to look in the LOG. It will tell you what the
equivalent JDOQL string form is for a JDOQLTyped query, and it will also have a
block about "QueryCompilation". That should be the same as the equivalent JDOQL
string based query. That is where your debug starts
> Provision of a typesafe refactor-friendly query capability for JDOQL

> There are various querying capabilities of this type around. JPA2 has its
> Criteria query API. Third party solutions like QueryDSL also exist, in its
> case providing a JDOQL implementation (as well as JPQL, and HQL). We should
> seriously consider introducing something along these lines in the JDO2.4
> timeframe.
> There is a comparison of JPA Criteria with QueryDSL over at
