Problem with calling Delphi RO server from .NET client after upgrading to RO 10.0.0.1621

Hi RemObjects

After having upgraded to RO 10.0.0.1621 I can no longer call operations with array of string parameters from .NET clients - However I am able to call the method from a Delphi client.

The problem occurs inside this routine: procedure TROSerializer.Read(const aName: string; aTypeInfo: PTypeInfo; var Ptr; ArrayElementId: Integer = -1; Attributes: TParamAttributes = [ ]); in “uROSerializer”.

I am running Delphi 12.2 and Visual Studio 2022 LTSC 17.8

I wrote a small server to isolate/demonstrate the problem the - i have inserted the rodl for that below.

Thanks in advance
Christian

Hi,

I can reproduce this issue.

as a temporary workaround, add {$DEFINE CODEGEN4_SKIPGENERICARRAYS} into RemObjects_user.inc, close Delphi IDE and launch install_DA.cmd (or install_RO.cmd) from C:\Program Files (x86)\RemObjects Software\Build folder with admin rights
