Hi guys
I have another little Problem,
I want to add a modal login dialog. For a first test I have copied the code of the modal dialog from the ZK Component Explorer.
When I want to open the Dialog by clicking a test button the following error message appears:
"Event Processing Thread is disabled"
Where can I switch on this feature?
For further information have a lokk at the tomcat logs:

Do you have any hints for me. Thanks an lot and best wishes,

Check the zk.xml and comment the line:
<system-config>
<disable-event-thread />
</system-config>
hi,
my zk.xml is purely empty...
which event listener class do i have to register??
I want to execute the following code.
<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<zk>
<style src="style.css"/>
<zscript>
<![CDATA[//@IMPORT
]]><![CDATA[//@DECLARATION
public void doLogin(){
final Window win = (Window) Executions.createComponents(
"login.zul", null, null);
win.setMaximizable(true);
win.doModal();
}
]]></zscript>
<window title="Venta Administration Services" border="normal" height="100%" width="100%">
<button label="login" onClick="doLogin()">
</button>
</window>
</zk>Are you sure, you have WEB-INF/zk.xml file and it is empty? Because this really looks like you have event threads disabled with this config.
Btw. you can use modal-like dialogs even when event threads are disabled, just use win.doHighlighted(); method instead.
Maik, I ran your code with ZK 3.6 and no usage of zk.xml and works OK (Showing an error because I do not have a login.zul file).
As a suggestion check your web.xml or your ZK jar files...
Hi edudant and YamilBracho,
thanks for your posts.
So here is my zk.xml

Hi,
if you're using Spring, please try to add the following to your zk.xml:
<system-config>
<ui-factory-class>org.zkoss.spring.bean.ZkSpringUiFactory</ui-factory-class>
</system-config>
Does this help?
Cheers,
Another Maik...;-)
Hi Maik,
thanks a lot for your post. I will try that, when I am back home. Do I have to call the
win = (Window) Executions.createComponents("login.zul", null, null) - function or another one during I am using spring?
Thanks,
the other other Maik
Hi all. I had the same problem, but after adding mentioned code to the zk.xml i wasn't able to start any other xxx.zul file than the one designed for modal login.
The resulting error looks like this, but I'm not able to understand it:

Do you have any ideas?
Thanks in advance for your hints,

Hi all,
I have the same problem than dermaik81 (after having used ZK+Spring+Hibernate from Zeta).
I also use only these lines in my zk.xml :
<system-config>
<ui-factory-class>org.zkoss.spring.bean.ZkSpringUiFactory</ui-factory-class>
</system-config>
But, I get the same errors than Spanier...
Still no ideas?
Best regards.
