Unable to call show() Method with REST plugin

[Johannes Geppert]

I try to migrate a project from codebehind plugin to convention plugin together with the rest plugin.

The most things works fine, but when I try to use the show() Method I become following error message

The show() is not defined in action class com.opensymphony.xwork2.ActionSupport

I can't find any reasons for this error.
Does anybody know this message?

Best Regards
