Using @Strategy in Queries not working properly
-----------------------------------------------
Key: OPENJPA-1577
URL: https://issues.apache.org/jira/browse/OPENJPA-1577
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.0.0-beta2
Environment: Ubuntu 9.10, Maven 2.2.1, Spring 3.0.1
Reporter: Oliver Ringel
I try to use a field that is annotated with @Strategy in a Query.
I expected that everytime the query is executed the toDataStoreValue method of
the ValueHandler is called to prepare the correct values for the SQL query.
This is only happens once. The next time the Query is executed the ValueHandler
is not called.
Here is the interesting part of the logging
1st call:
[DEBUG,Query,main] Executing query: [select s from SimpleEntity s where s.base
= :base and s.name = :name] with parameters: {name=james, base=1}
toDataStoreValue: 1
[DEBUG,SQL,main] <t 805562662, conn 2071272094> executing prepstmnt 1531692262
SELECT t0.id, t0.version, t0.base, t0.street, t0.my_name FROM some_objects t0
WHERE (t0.base = ? AND t0.my_name = ?) [params=(String) base1, (String) james]
2nd call:
[DEBUG,Query,main] Executing query: [select s from SimpleEntity s where s.base
= :base and s.name = :name] with parameters: {0=2, 1=henry}
[DEBUG,SQL,main] <t 805562662, conn 2071272094> executing prepstmnt 106030716
SELECT t0.id, t0.version, t0.base, t0.street, t0.my_name FROM some_objects t0
WHERE (t0.base = ? AND t0.my_name = ?) [params=(String) 2, (String) henry]
You can see that the parameter list has changed after the first call. Some kind
of transformation (caching?) prevents calling the ValueHandler again.
This is only a vague presumption.
