Empty Dependency

[Martin Haase]

Hi,

I am faced with an ERROR in the Velocity filter template of an LDAP
DataConnector. The connector looks like this:

    <DataConnector id="myLDAP2" ...>
        <Dependency ref="someAttributeXYZ" />
	<FilterTemplate>
            <![CDATA[
                (member=uid=$someAttributeXYZ.get(0),dc=some,dc=domain)
            ]]>
        </FilterTemplate>

The error the templating engine spits out approximately says that there
is no value for "someAttributeXYZ", so it cannot dereference its first
element (ArrayIndexOutOfBoundsException). This is IdP v3.3.x.

Now I am baffled: I was under the assumption that if an
attributeDefinition returns no value for an attribute, the dependent
attributeDefinitions or dataConnectors would not fire in the first
place. Obviously this does not seem to be the case.

I now do have a workaround that checks on $someAttributeXYZ.size() using
a Velocity #if, but it is ugly because there needs to be some bogus
filter string in the #else branch as well for the DataConnector to not fail.

I feel there should be something like a <Dependency
ref="someAttributeXYZ" *emptyisok**="false"* />. Am I missing something,
or can this be reached via other means?

Regards,

Martin
