Extension v1.0 NAV 2017

mcoscas

Hi everybody,

Is it possible to add a customized codeunit in an extension that contains the follow line of code:
PagLServiceOrder.WebClient.PAGE.GetRecords(Rec) where PagLServiceOrder is a page variable with SubType "Service Order" and
WebClient is a page part (under FactboxArea) of the "Service Order" page (5900).
With this line of code I get an error during the installation of the extension (dotnet error about reference null)
When I remove this line it works fine.

Thanks,
Michael
