WebApplication.ShowMessage blank

[newuser]

Hi,
When I call WebApplication.ShowMessage I get a blank box with an OK button.
So the tekst and the background are white.
When I add ,smNewWindow I get no box at all just the waiting signal…..

ShowMessage() expects a string as a parameter Are you passing a string?

smNewWindow is kept for compatibility with previous versions. It doesn't make any sense to use it in a modern web application.
