[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2100) Allow same parameter more than once in a single restriction

Diego Ballve commented on JBSEAM-2100:
--------------------------------------

I have not used components.xml for it but I think it would be something like this:

    <fwk:entity-query name="contracts">
        <fwk:ejbql>from Contract</fwk:ejbql>
        <fwk:restrictions>
            <value>contract.sellerId = #{currentUser.id} or contract.buyerId = #{currentUser.id}</value>
        </fwk:restrictions>
    </fwk:entity-query>

Current implementation would give you error message ('max 1 vb per restriction' or something like that). My point was that if vb repeats, it can be counted as 1 vb and restriction is still acceptable.

> Sometimes you need to compare a restriction parameter w/ many fields in the same restriction. In those cases, I feel that it makes more sense to have multiple comparisons than to write something like :param IN (select1, select2, ...).
> The attached patch allows that, registering the same value binding once per restriction but allowing it to appear multiple times.
