debugging zk project in eclipse return "Source not found." Error -

I am new to zk. I am creating a new .zul file when I navigate to my new page in the browser, "Source not found". The error appears in the eclipse in fault mode, while the running application works right I am using APK Tomek 7.0 and Eclipse Juno with the Zuck Studio plugin.

The problem was in the Zul file that tags should be inserted from the tag!
