Hello

Congratulatios for this cool framework.

I'm new with the zk framework. I need more performance in the zul files.

I have been mapping zk with Hibernate ussing the OpenSessionInViewListener in the zk.xml and i need to show the message exception from the db to the client via javascript (no Messagebox) because i loose performance using Messagebox.show()

This is my code:

in the index.zul:
---------------
<window id="winIndex" use="com.xxx.mw.rol.controlador.IndexWindow" width="300px">


in the com.xxx.mw.rol.controlador.IndexWindow.java:
--------------------------------------------------

public void ingresar() throws Throwable{
try{

//excluded code here

}catch(Throwable ex) {
Clients.evalJavaScript("alert('STATIC MESSAGE')");
}
}

I use the Clients.evalJavaScript to show a STATIC message but i need to show the hibernate exception message.

Actual message:
Clients.evalJavaScript("alert('STATIC MESSAGE')");

Needed message:
Clients.evalJavaScript("alert(' ? ')");

where

? = ex.toString() // Exception message from hibernate java in the SERVER SIDE.

How pass the ex.toString() java message to the Clients.evalJavaScript() function as javascript code for evaluation in the CLIENT SIDE?

Thanks for your help.

Best regards.
