I'm using Hibernate 3.2.2 and jBPM 3.1.4 in a Seam 1.2.1GA environment.

I have a problem with a query that should return VariableInstance entities
based on a particular name and value. The variable instance is actually an
instance of org.jbpm.context.exe.variableinstance.LongInstance.

The following query returns lots of rows and one of these results shows the
value as 1654.

| SELECT
| vi
| FROM
| org.jbpm.context.exe.VariableInstance vi
| WHERE
| vi.name = 'memberId'
|
However, when I then run the following query, no results are returned.

| SELECT
| vi
| FROM
| org.jbpm.context.exe.VariableInstance vi
| WHERE
| vi.name = 'memberId'
| AND
| vi.value = 1654
|

How can I select a variable instance based on a long value? Any hints or
suggestions would be greatly appreciated, as I really have run out of ideas!

Thanks in advance, Pete.
