Register Application Level Converters
Available for ZK: EE
since 6.0.1
You can register application level converters1 by setting library-property(org.zkoss.bind.appConverters) in zk.xml.
<library-property>
<name>org.zkoss.bind.appConverters</name>
<value>foo=my.FooConverter,bar=my.BarConverter</value>
</library-property>
Then use them by converter name.
<label value="@load(vm.message) @converter('foo')"/>
<label value="@load(vm.message) @converter('bar')"/>
Register Application Level Validators
Available for ZK: EE
since 6.0.1
You can register application level validators1 by setting library-property(org.zkoss.bind.appValidators) in zk.xml.
<library-property>
<name>org.zkoss.bind.appValidators</name>
<value>foo=my.FooValidator,bar=my.BarValidator</value>
</library-property>
Then use them by validator name.
<textbox value="@bind(vm.name) @validator('foo')"/>
<textbox value="@bind(vm.value) @validator('bar')"/>
Print ZK Bind Debugging Information
since 6.5.2
Turn on printing ZK Bind debugging information will print lots of messages during run-time which may be helpful for dubugging. Please do not enable it in the production environment.
To enable it, add the configuration below (default is false) in zk.xml:
<library-property>
<name>org.zkoss.bind.DebuggerFactory.enable</name>
<value>true</value>
</library-property>
The printed message looks like:

Debugging Tool: ZK Binding Tracker
The above configuration will print messages on the server’s console, and it is system-wide, which means debugging information of all pages will be printed and it might become hard to read. We therefore hereby present you a tool: ZK Binding Tracker which is a Chrome extension that can be installed on your Chrome browser. It can display the debugging information for the current ZUL page in rich format.
For more details, please refer to Small_Talks/2013/June/ZK_Binding_Tracker_-_A_Chrome_Extension.
