Hi Cathy,
>BeforeRender and AfterRender are not native methods of a reportlistener so that makes me ask ... where are you calling these methods? Maybe the problem is with the code that is meant to call these methods.
They're Doug's equivalent of DoBeforeRender and DoAfterRender in your
"Report Writer in Action" classes, called in the same places -- i.e., the
listener's Render(params) method consists basically of BeforeRender(params), then
ReportListener::Render(adjustedparams), then AfterRender(params). Their
defaults simply call the successor's method.
Should be straightforward -- BeforeRender sets the adjustment props,
AfterRender resets them to zero.
I just can't figure out what circumstance would cause the listener's
Render method not to fire (WAIT WINDOW immediately after Render's
LPARAMETERS line confirms this), but, since the object is being rendered
(albeit incorrectly) on the page, obviously a render from further up the hierarchy
is being performed.
My only guesses so far are a stretch:
(1) Somehow the Render for my initial Heading object and my initial ColumnData
object are getting a bad param. But that would not explain why they render correctly
when they are the only objects, rather than just the initial ones of two or more.
(2) All of the objects' EvaluateContents DO change the Text, and I set
Reload to .T., so I wonder if that's somehow initially affecting the engine as it
proceeds to the Render.
