For some time now, I have been experiencing an issue in the designer. When I work on views, run them, and confirm, sometimes the parameter configuration disappears. This happens occasionally. Has anyone encountered this problem?
I've experienced a very similar issue with session variables. They would disappear. I would add them back in, save project and close the Designer, but they would disappear again. I remedied this by doing an export of the project from the gateway, deleting the project and then re-importing. Then I created the variables again and saved the project and they stayed. It appeared to be some sort of corruption within the project somewhere.
