Hi
Can someone tell me what is the wrong in the following code
demo1.zul
<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<zk>
<window id="AppRoles" title="Application Roles" border="normal"
apply="org.zkoss.bind.BindComposer"
viewModel="@id('role') @init('test.demo1VM')">
<checkbox label="Show only active"
checked="@bind(role.IS_ACTIVE)" />
<button id="submit" label="Submit" onClick="@command('save')" />
</window>
</zk>
demo1VM.java
package test;
public class demo1VM {
private Boolean IS_ACTIVE = true;
public Boolean IS_ACTIVE() {
return IS_ACTIVE;
}
public void setIS_ACTIVE(Boolean iS_ACTIVE) {
IS_ACTIVE = iS_ACTIVE;
}
}
When i run, the following error occurred
ype Exception report

Hey Senthil,
You're not using the java naming pattern. And then the EL resolver is attempting to access the private variable IS_ACTIVE, but as a private variable, it cannot be accessed from outside.
You should refactor your code using the java standarts, try this way:
demo.zul
<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<zk>
<window id="AppRoles" title="Application Roles" border="normal"
apply="org.zkoss.bind.BindComposer"
viewModel="@id('role') @init('test.demo1VM')">
<checkbox label="Show only active"
checked="@bind(role.active)" />
<button id="submit" label="Submit" onClick="@command('save')" />
</window>
</zk>
demo1VM.java
package test;
public class demo1VM {
private Boolean active = true;
// I do believe that EL can resolve this, but if don't work, you'll have to change the method name to getActive()
public Boolean isActive() {
return active;
}
public void setActive(Boolean active) {
this.active = active;
}
}
HTH,
Madruga
Hi
Thanks. But still gives the same problem
how did you define you checked bound property? You had:
checked="@bind(role.IS_ACTIVE)
with the new code it would be
checked="@bind(role.active)
Note like Madruga mentioned, you might need a getter for a wrapper Boolean (getActive()) instead of isActive()) isActive should work fine for the primitive boolean. I usually use primitives for my booleans so haven't tested with Boolean.
Note, I just had to implement this kind of thing myself just now in my VM and it's working just fine...
//VM
private boolean showShared;
public boolean isShowShared() {
return showShared;
}
@NotifyChange("productGroups")
public void setShowShared(boolean showShared) {
this.showShared = showShared;
}
//zul
<hbox> <checkbox label="Show Shared" checked="@bind(vm.showShared)" ></checkbox> </hbox> <listbox model="@bind(vm.productGroups)" selectedItem="@bind(vm.selectedProductGroup)">
I have the same problem too!
I use a boolean property name of "CommCheck1_1"
get error -> PropertyNotFoundException: Property 'CommCheck1_1'
when I change the property name to "commCheck1_1"
working fine , no problem now
Is it a bug? or some framework issue (spring)?
Seems no bug to me, because properties may not start with a capital in Java. ZK will not find the right getter/setter for the property.
The sample works well for me: MVVM test
Just copied your code and change 'public Boolean ISACTIVE()' to 'public Boolean getISACTIVE()'
To solve this issue you can use XJC plugin to generate getter for Boolean field, please refer to getter for boolean properties with JAXB
