Access Violation in reports with variables after upgrading to 21.02.

Hi,

I've upgraded to Report Builder 21.02 from 11.08. We're using it with Delphi 7. I'm trying to open and convert some template (rtm) file but get an Access Violation in rbRAP217.bpl when calling ppReport1.Template.LoadFromFile.

The error occurs in reports using variables. If I remove the variable the report opens ok. Any help would be appreciated.

  • To add to this, it seems to only error when you use a data field in the onCalc of the variable
  • Hi Alpesh,

    If possible, please send a template that causes this error to support@digital-metaphors.com and we'll take a look at what is happening.

  • Hi Nico,

    I've sent a couple of templates in. Let me know if you need any other information.

    Thanks
  • Hi Alpesh,

    I'm able to open the provided templates using RB 21.02 with D7 and also with the latest, D11.

    Perhaps you have a corrupt installation. Here's a link to an rbWiki article with detailed steps for cleaning up a corrupt installation. Give it try..

  • Hi Nard,

    I've done some more investigation. We're only experiencing this within our application. When I add a data field to a variable and compile it, we get the Access violation. It compiles ok if we use a function or add a report object. I haven't been able to replicate this in a test app to send you. It works fine in version 11.

    The call stack and exception we're getting are below. Any ideas or help on how I can get to the bottom of this would be much appreciated.

    Thanks

  • Hi Alpesh,

    To research, I need an example I build and run in the debugger.

    The call stack ends with TraProgramStatement. That does not provide a clue.

  • Hi Nard,

    We've found the AV is reported when using Mad Except and 'crash on buffer overrun' is turned on. I can send you a simple app build with Mad except if that would help.
