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

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, set value to true (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:
