More info.
i´ve added BREEZE to the zkspringboot-demo-jar project and i got the same problem.
Just add the breeze dependency in the pom.xml and setup the theme in the the zk.xml and the problem appears during the app start up.
I´m using eclipse STS.
Thanks in advance.
Hi there,
How do you add dependencies to your project? Are you adding the jars manually, or using a dependency management tool such as maven or gradle?
I can see in the error that you are adding breeze-9.6.0.1.jar to your project. If you are using the default ZK spring boot starter, the default ZK version of the starter is 9.6.0.
It is possible that the theme fails to register if the versions are not matching.
If you are using maven / gradle, I recommend building once from command line, just to make sure there is no exception when resolving the dependencies. Sometime Eclipse will hide stuff from you, which can cause projects not to work as expected.
The error showed here indicates that the config parser failed to parse the breeze theme jar config (which explains why the theme is not loaded). However, there should be a "caused by" clause further below that error stack. If you don't see that error in your log, you can try putting a breakpoint at org.zkoss.zk.ui.sys.ConfigParser.parseListener(Configuration, Element)
on the line:
log.error("Unable to load a listener, " + el.getLocator(), ex);
and check the content of the exception object ex to find out the root cause of that failure to parse.
FYI since there is at least two reported issues with similar error stacks / messages, I have created a ticket to centralize this debugging: https://tracker.zkoss.org/browse/ZK-5245
