Summary: string-binding NPE
Initial Comment:
I have a ValidField with the binding:
<string-binding name="displayName"
key="investigationListFilter-investigationName"/>
When the page loads I get:
java.lang.NullPointerException Stack Trace:

I think this is because AbstractComponent.getString()
uses the engine of the current page to find the i18n
strings, and the page does not get attach()ed until
after its properties have been bound.
This could probably be fixed by moving the attach()
into PageLoader.loadPage()
