Has anybody experiences with spying Editfields in Java?

We are using Protoview V5.0. as Toolkit.

There are problems with recognising Editfield.
Winrunner (V7.01) doesn't support that normally (he recognise the text and the field, but doesn't give the value back when we are running the test). The text is visible but it is empty for the application.

Thanks for your help!
