Hi,
I'm quite new to zk, so I probably overlook something.
I've created a composite component that implements AfterCompose
This source throws a "java.util.ConcurrentModificationException" at the point where I try to insertBefore.
oklbl is autowired.
public class MD extends Window implements AfterCompose {
private Label oklbl;
@Override
public void afterCompose() {
Executions.createComponents("/composites/MasterDetail.zul", this, null);
Components.wireVariables(this, this); // auto wire variables
Components.addForwards(this, this); // auto forward
for(Component c: (List<Component>)this.getChildren())
if(c instanceof Button) {
this.insertBefore(oklbl, c)
}
}
}
How can I insert a control before another in afterCompose?
jaan
I think this is basic java ConcurrentModificationException when modify a List in it's element iteration.
I don't know what you are doing, however, regard to your code, you can try this
Button t = null;
for(Component c: (List<Component>)this.getChildren()){
if(c instanceof Button) {
t = (Button)c;
break;
}
}
if(t!=null){
this.insertBefore(oklbl, t)
}
