[Xdoclet-user] Re: Problem generating DataObject with aggregatedfields

Marcus Brito Tue, 26 Feb 2002 04:34:57 -0800

I gave up tryin to figure up the correct order to generate everything in
my project and changed the dataobject.j template so it no longer user
XDtDataObject:dataObjectClassNameFromInterface. Instead of it, I
required @ejb:aggregate to have a type parameter informing the
DataObject class name. All references to
<XDtDataObject:dataObjectClassNameFromInterface/> in the template were
substituted for <XDtMethod:methodTagValue tagName="ejb:aggregate"
paramName="type"/>


Now it requires a bit more information from me (and is somewhat prone to
errors, as I need to type the full class name for the data object) but
at least works. Anyone who is facing problems similar to mine can
benefit from this modified template.

Please note that I'm *not* saying that this is better than the current
template. Just needed something to solve a specific problem of mine and
maybe someone else may also need it.
