Master detail problem

I am having a problem with master detail reports that I dont understand - basically they dont work

I have two tables and I have set up a master detail relationship between them such that if i click on an entry in table1 just the linked entries in table 2 are displayed. OK so that bit works fine.

If I add a masterdata band to FR conect to table 1 and place a field on it from table1 and run my report, then I just see the field displayed on each band as I would expect.

I then add a Detaildata band and connect to table 2 and add a field from table 2 to the report. If I now re run the report (or preview) I get a blank report. If I delete the table 2 field (i.e. the detail field has no data on it, I get the same i.e. a blank report

Any ideas?

    Anyone else having an issue here?

    Sorry GPI - I should have said thanks, but no that made no difference.

    I am making progress - master band now prints, but detail is always empty. (fields in detail table are populated)

    Sorted - I had two data sources that connected to the same table, I used one for the master band and the other as my mastersource in the detail table.

    I have the same problem. New Version Fastreport 4.13.1 and XE3 Architect. Masterdetail prints not any information. Same with Detaildata. All other bands are working.

    Generated a new report with the wizard and connected database. I use tfrxdatabase and unidac components with C++ Builder.

    I have made several tests. In some case if masterdetail is not assign a database, then detaildata works. But get my report not workable.

    I get it now work. Use more masterbands with one overlay at the report. I must remove all assign datasets from any masterband. At first i had used 2 tfrxdatabase for master- and detailband. Now i use only one tfrxdatabase for masterband, but did not assign to any band. Then put the tfrxunidactable inside frxreport assigned to the detailband and connect with master and masterfields.

    If i print the first time this report then there is no output at the detailband. After that it works. I have solved it by calling PrepareReport at starttime.
