Alan Gardner updated TAPESTRY-1858:
-----------------------------------
Description:
Receive a null pointer exception when using paging in the grid component. The
grid component works fine until you try to go to another page (besides the
first page). It doesn't seem to matter what the paging size is, I even tried
the default paging size of 25.
An unexpected application exception has occurred.
