[jbosstools-dev] CDI/Seam security xml weirdness

[Max Rydahl Andersen]

I found this http://seamframework.org/166557.lace using impl in config too.

So sounds like docs bug. Weird.

The only case that seems an exception is 'Virtual Producer Fields', here an abstract type may be declared as a bean, but concrete bean instance must be set as its value by <s:value> child tag.

I would expect docs to say something explicitly about that, but nothing in docs supports it. I think such a feature would be not only great but also unpredictable. Suppose there are 10 implementations of Identity in classpath, each with its own set of qualifiers and each used in its own way. What node <security:Identity><s:modifies/></security:Identity> is supposed to do? Should it replace all 10 beans with one configured by this node? Which of 10 implementations should be selected for that?
