So I've finally found out how it can be done. Through action context I can get
value stack and find any possible value being already there.
ActionContext.getContext().getValueStack().findValue("valuename");
Not exactly nice as the parameter is not pushed to the action by the caller
but the action must dig on the value stack for it, but at least it works...
