Component - Under Cover Agent

                                Under Cover Agent         

Invoking UCA can create new instance of process. In general, UCA's are associated to external services. Creation of new instance through UCA provide lots of flexibility.

Consume Message - If it is checked, then subsequent process will not be able to pick message. In case of unchecked all successive processes will be able to create new instance.

Durable Subscription - In normal process, token will wait for message. As soon as, message will reach at token. It will create process instance.

But what if, message has been send and token has not been reached at implementation. In that case if durable subscription is checked, token will not wait at implementation. It will directly execute.

Coach View - Display error message at Table's Component row level

Display error message at Table's Component row level -

To achieve :
  

Validation Code : (Text Box)

for(var iCount=0; iCount<tw.local.testBO.listLength-1; iCount++){

      if(tw.local.testBO[iCount].userName == null || tw.local.testBO[iCount].userName == "" ){

         var componentName = "tw.local.testBO[" + iCount + "].userName";
         tw.system.addCoachValidationError(tw.system.coachValidation, componentName, "Please provide user details...");
    }                                                   
}    


Validation Code : (Combo Box)

For combo box, it could not be achieved with binding because binding is having list.  It can be done through selected item.

Configuration -- Selected Item -- Assign a Name Value Pair variable. Suppose variable name is "userNameNV".

for(var iCount=0; iCount<tw.local.testBO.listLength-1; iCount++){

      if(tw.local.testBO[iCount].userNameNV == null ||
                                tw.local.testBO[iCount].userNameNV == "" ){

         var componentName = "tw.local.testBO[" + iCount + "].userNameNV";
         tw.system.addCoachValidationError(tw.system.coachValidation,
                                                                  componentName, "Please provide user details...");
    }                                                   
}
