Request for @In: Don't inject null

[newlukai]

Hi,

I've a request for the @In annotation.
In my component I've two fields which are injected. Because I use the component for additional requests, which don't have values for those two fields, I would appreciate a parameter to tell Seam to not inject the fields if there isn't a request parameter.
If I use @In without parameters Seam tolds me, that there has to be a value. And if I use @In(required=false), Seam injects null. If there was a @In(dontNullify=true) or sth. my component would receive the initial values for those two fields which then are kept over several requests.
Is that possible?

Regards

OK. Maybe I didn't explain it understandable.

I want a parameter to tell Seam not to overwrite existing fields. If I've a field in my component, which is not null and Seam doesn't find a value in its context for this field, I don't want Seam to overwrite my field with null. Seam should do nothing.

Don't use injection. Use an ordinary lookup Contexts.getXXXContext().get("name") or Component.getInstance("name", true).
