I have written Order Repository queries, which were parse correctly when we have 2.00.
However, the same queries failed after we upgrade our server in 2.02.
After some trial and error, I believe it was caused by the fact that I encode my query parameters (though it was a good practice).
Not all encoded queries failed, some worked. But if I turn off the encoding, the failed ones is working again.
This failed (but was working in 2.00)
