Getting an error Cannot assign a TFieldList to a TStringList

rajeev_kumar · March 2022

Hi,
I am migarting my application from delphi 4 to 10.4. Currently I am using report builder 21.01.
In older version, delphi 4 when assigning datasorce to TppBDEPipeline its working fine. But after migartion in delphi 10.4 its giving an error "Cannot assign a TFieldList to a TStringList" on assigning datasource to TppBDEPipeline.

Code example:

var
FPipeLine : TppBDEPipeline;
begin
FPipeline.Datasource := DatasourceImprRapt;

Hi Rajeev,

I'm a bit unclear about where the error is occurring. Assigning a TDatasource object should not cause a TStringList error. As a test, set your library path to \RBuilder\Source\ and trace further into the RB source to see where this error is happening.

Hi nico,
As suggested we have added \RBuilder\Source\ path to our Delphi library path and after that we are facing issue which we have already discussed in the below link.

As per above link you have suggested us to install everything after cleanup. We did the same but still facing the issue while building our application. We have checked all the dependencies but could not found anything at our side. Please suggest us further on the same.

Thanks
Rajeev
