Calling custom business service in named method user prop

 Hello,

I have created a custom business service MyTestBS, that has 2 methods

1. TestNoArg - that has no arguments

2. TestArg - that has one input argument of type string

I want to call this on named method user property on bc/applet.

TestNoArg works.

But when i try TestArg and put also argument in named method value, then the call fails.

Any idea how to call a custom method that also has argument(s)?

thanks
