[ovirt-users] WebUI error with nightly 4.0.7

Hi, since a few days, after the upgrade my dev machine to the nightly repo of 4.0.7, I'm getting these kind of errors from the WebUI after a few minutes the ovirt-engine is up: Error while executing action: A Request to the Server failed: java.lang.reflect.InvocationTargetException The errors go away if I restart the engine service, but after about 15 minutes they show up again. These errors are very annoying as I cannot use the UI unless I restart the engine. When I use my Mac I also get other errors like this: ERROR: Possible problem with your *.gwt.xml module file. The compile time user.agent (gecko1_8) does not match the runtime user.agent value (safari). Expect more errors. Does anyone knows if those errors will be corrected in a future release? Thanks, Alessandro
