In IM form, there is a link called send mail. That is an HTML Viewer. Because of that print page option is not working. So we are changing it to Link Label. In display option, we are using rad function "us.external.search". we are storing mailto in local variable under RAD expressions. That Functionality is fine. But when we are trying in Web Client, we are getting below mentioned text in POP uP.
"function not available through web browser interface".
How to resolve this?
