Ameera Akmalia 0 Posted January 7, 2019 Hello.  I created a datasnap client-server application. Whenever I re-open the project or make changes in ServerMethods unit, the error occurred when I try to activate the clientdataset in the ClientModule unit. Anyone knows how to solve this issue? Thanks in advance.  I have attached the screenshot of the error occurred. Share this post Link to post
