Master/Detail not being honored

Hi,

I am using RB 7.02 with Delphi 7. I have a report with two groups on the
main report: group[0] is by rep_id and group [1] is by state. The main
report is connected to a clientdataset In the state group footer I have a
subreport that has a crosstab in its summary section. The data for the
crosstab is a clientdataset whose MasterSource is set to the main report's
clientdataset's datasource. MasterFields are set to 'REP_ID;STATE'. I print
my report for a case where there are two rep_ids and two states per rep_id.
When scrolling forward in my report, everything looks good. When I get to
the end of the report and I start to scroll backwards page by page, I get to
the page that shows the crosstab it shows the data for the wrong state (it
shows the state from page 4 on page 3, etc.). What am I missing here?

Natalie,

Try setting the Report.CachePages property to True. If this does not help,
please send a working example demonstrating the problem in .zip format to
support@digital-metaphors.com and we'll take a look.

Natalie,

Exactly how big is your report going to be? The CachePages property does
have the potential of causing memory issues but this is machine dependant.
If your report mainly going to be text and lines, you should not have a
problem. If it contains numerous large images, we may have to look at an
alternative approach.

It is not the expected behavior. We support proper TDataset descendents and
have no problem using well behaved datasets. The only issue that can arise
is if the client dataset is not a proper TDataset descendent. This means
that it must support bookmarks on the dataset. Can you reproduce the error
with our demo reports? What client dataset class are you using? If you test
using the BDE or ADO (I don't know what database you are using) does the
problem go away?

Try using the MasterFields and MasterSource properties to link the client
datasets. Make sure that you do NOT use the datapipeline properties when
using delphi linking, ie. do not assign DataPipeline.MasterDatapipeline and
MasterFieldLinks. That may be one cause.
