you may provide the annotation @SuppressWarnings("unchecked")
this will probably remove the warning in your IDE.

the warning occurs, because of the performQuery returns just a List-Object wich is not typesafe.

Betreff: Java5: the expression of type list needs unchecked conversion

Hi all,

I'm using Eclipse and Java6 now. Whenever I do anything with
performQuery() the IDE complains that
the expression of type list needs unchecked conversion.
I'm sure I could turn that off in the IDE but is there a way to
write it so that the warning goes away? I tried casting.

    Squashing consequences of one Java 5 feature with another... nice :-)

    I wonder how we can address this at the framework level, without
    having to support two separate jdk-specific builds of Cayenne? Wonder
    how other frameworks handle that (I suspect they don't)?

    Ignore the warnings :)

    In intellij you can turn off the warnings in the "errors" preferences
    pane. There are also compiler options to make the complier not
    whine, but I don't know what the options are.
