extend client side java bean

[maik huber]

I am not sure how to deal with the following:

I have a JavaBean on the server which I convert to a Javascript Object
on the Client using DWR.
On the Client I extend the JS-Object with additional methods and
properties. These fields are only needed on the client side.
Now when I send the Object backt to the Server I get this warning:
"Missing java bean property to match javascript property"

How can I suppress this warning or how do I correctly extend a JavaBean
on the client that can be sent back to the server without generating
this warning?

Thank you!

1) Mike's replies here should help (use class mapping):

Or ...

2) Remove the client side properties before sending the object.

Adding to David's post, since 3.0 RC2 there's actually a third
"undocumented" alternative that may come in handy if you are
adding the same properties to a lot of different kinds of objects:

3) dwr.engine._excludeObjectAttributes.myprop = true

The above will ignore the "myprop" attribute in *all* objects
sent to the server.
