When the creationComplete event is fired on a TitleWindow

[powers]

I have a title window that I'm creating and passing data to.  I want to create children of the title window based on this data and I don't want to show the title window until the children have been created and added to the title window.  

titleWindow = new SomeComponent();
titleWindow.data = someData
titleWindow.createSubChildren();
                               
PopUpManager.addPopUp(titleWindow, this);
titleWindow.center();

When I call the createSubChildren method, I get errors because it doesn't seem that any of the titleWindow's sub containers have been created. I thought using the new operator to create the component would create all of the children but it doesn't seem to happen until it is actually added using the PopupManager.  Any ideas?

Children are created in addPopUp (when added to a parent).  creationComplete may be fired in there as well.

titleWindow = new SomeComponent();

PopUpManager.addPopUp(titleWindow, this);
titleWindow.center();

Components don't get initialized until added to a container and createChildren is called as part of the initialization process.

Since this is your own subclassed component you can override createChildren and call createSubChildren from there though you should check whether your data has been set before you try creating anything.

Additionally in the setter for your data you can check to see if the component is already initialized and if so directly call createSubChildren otherwise wait for initialization.

The TitleWindow by default is not made visible until after intialization so that should be ok.

We do something similar to this to load modules at runtime, passing in the Url or Class as the 'data'.
