Description

The fix for TAPESTRY-2636 results in a NullPointerException when my form is posted. If I revert back to the previous version of Grid.java (http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/main/java/org/apache/tapestry5/corelib/components/Grid.java?view=markup&pathrev=690060) everything works fine again.
