This component renders fine when the page is first viewed. However on
first postback I get:
java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
at java.util.ArrayList.get(ArrayList.java:322)
Nevermind, I figured it out. As soon as I assigned an explicit id to the
child component created in the constructor the problem became obvious.
Just in case anyone is interested:
In the "restore view" phase, a new instance of each UIComponent is
created. Instances of the previous children are then created and added
to the UIComponent. So there are then two children of this component.
And trying to restore one serialized child for a component that now has
two children causes the array-out-of-bounds.
