Hi,
I'm trying out the newly released ZK 6.0.0-RC with my current installation of ZK Studio 1.0.1 (in SpringSource Tool Suite 2.8.1). I've noticed a couple of problems:

1) Trying to use the Visual Editor gives me this error:

An internal error occurred during: "Visual Editor hosting project...".
org/zkforge/apache/commons/el/ExpressionEvaluatorImpl
2) Binding to a command causes the IDE to give me the error "Invalid character constant". For example, that error is given if I add this line to my .zul file:

<button label="New" onClick="@bind('newOrder')"/>
As a workaround to #1, I can go in the project properties and tell the visual editor to use ZK 5. But if I do that, the visual editor fails when I try to use any new ZK 6 features in my .zul files. For example:

Fail to render : Method setViewModel not found for class org.zkoss.zul.Window
Is there a version of ZK Studio publicly available that works with ZK 6.0.0-RC? Maybe just a nightly build or something?
