Second JITPipeline doesn't fire?

rbuser

I have two JITPipelines with separate GetFieldValue routines. Both are
sub reports on the same detail band but are not related. The second
GetFieldEvent doesn't get called when the report prints. Is there
anything I should be looking for? Thanks, Madt M.

Hi,

Be sure the second pipeline is properly connected to the second subreport.
From the design of the subreport, select the Report | Data option in the
main menu and select the second pipeline. Next, be sure there are fields
defined for the JITPipeline.

Nico -

Thanks for the response. I've been wrestling with this for a couple of days
now.

Everything you suggested was already in place. When I call ppReport1.print
the ppJITPipeline1GetFieldValue Event fires, but the
ppJITPipeline2GetFieldValue is never called. (I've put breakpoints on each
routine.)

As I mentioned:
- There is no MasterDataPipeline relationship between the two JITPiplines

As you suggested:
- Report / Data points at the correct pipeline
- The pipeline has fields
- The report fields all have the correct DataPipeline and DataFields
selected

Why won't th report call ppJITPipeline2GetFieldValue?

Stumped in St. Louis,

Hi Madt,

Using RB 10.04 and Delphi 7.

As a test, I created a simple report with two child subreports in the detail
band. I connected each subreport to a separate JITPipeline on my form each
of which were set to contain 10 records and a single integer field. I
implemented each OnGetFieldValue and assigned the values to the record
index. The report displays the data for both subreports correctly and the
OnGetFieldValue of each JITPipeline fires as expected. Are you able to get
the same results with a similar simple application?

OK. I figured out the problem: During the construction process I caused an
AV with the second JITPipeline. After the AV, the GetFieldValue function
call was severed and was never again called (even though the it appeared to
compile with the unit - blue dot on the left margin). I deleted the
original event from the JITPipeline and reentered the event with the
original code and it worked fine.

I caused the problem by overstating the number of records to be traversed.
Sigh. Even though I adjusted the record count and recompied the project,
that didn't correct the functionality of the program.

Thank you for your suggestions. BTW, I'm using Delphi 5 for this project.

Hi Madt,


I'm a bit unclear about the problem now. Are you still unable to get the
GetFieldValue event to fire? Is there another problem I can help with?

No, it works fine. To correct the problem I had to delete the event
(GetFieldValue) and re-enter it. After that, the program could be complied
and run. All good now. . .

Thanks, - Madt M.
