Register Application Level Converters

  • Available for ZK:
  • http://www.zkoss.org/product/zkhttp://www.zkoss.org/whyzk/zkeeVersion ee.png
Since 6.0.1


You can register application level converters[1] 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')"/>
  1. ↑ Application level converter only has one instance and is shared between all binders.


Register Application Level Validators

  • Available for ZK:
  • http://www.zkoss.org/product/zkhttp://www.zkoss.org/whyzk/zkeeVersion ee.png
Since 6.0.1

You can register application level validators[1] 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')"/>
  1. ↑ Application level validator only has one instance and is shared between all binders.


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.
