Rusty,
I'd do this differently if I were you. You really should have a single
"startingOffset". Then, have the nextPage() and previousPage() event
methods increment or decrement the startingOffset variable by 20.
Something like this:
public void nextPage()
{
this.startingOffset += 20;
}
public void previousPage()
{
this.startingOffset -= 20;
if ( this.startingOffset < 0 ) this.startingOffset = 0;
}
That should work perfectly fine. Then, you can have a single hidden input
which looks like this:
<stripes:input name="startingOffset"/>
