Simple query related to Java and WDTextViewSemanticColor

[Former Member]

Hi Experts,

I have created WD screen which fetches data from R/3 using RFC. The code is like as below.

public com.sap.tc.webdynpro.clientserver.uielib.standard.api.WDTextViewSemanticColor getMyOpenTripsColor(IPrivateList_trips_appView.IMyOpenTripsElement element)
  {
    //@@begin getMyOpenTripsColor(IPrivateList_trips_appView.IMyOpenTripsElement)
	for(int x=0; x<wdContext.nodeMyOpenTrips().size(); x++){
	  if(wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel().equalsIgnoreCase("Change Travel Request")){
		  wdComponentAPI.getMessageManager().reportSuccess("i "+ wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel()+ "  trpno "+ wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getTripNumber() );
		
		 return WDTextViewSemanticColor.CRITICAL;
		 
		}
	   if(wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel().equalsIgnoreCase("***Request Cancellation***")){
		  wdComponentAPI.getMessageManager().reportSuccess("j");
		return WDTextViewSemanticColor.MARKED1;
		}
	 }
	return null;

My problem is that there are 47 records in the table (wdContext.nodeMyOpenTrips().size() is 47). When I am executing the following code, only first record is being displayed. The wdComponentAPI.getMessageManager.reportSuccess statements return following records. There are many trip nos in addition to 1427. Why only first record is getting displayed?

hi1 47 
 i Change Travel Request  trpno 1427 
 
 hi1 47 
 i Change Travel Request  trpno 1427 
 
 hi1 47 
 i Change Travel Request  trpno 1427 
 
 hi1 47 
 i Change Travel Request  trpno 1427 

..many more rows (19 rows)

Please help.

Gary

Looks like you have a context structure

MyOpenTrips (node)
+ color (TextViewSemanticColor, calculated=true)
+ recommendedActionsTravel (string)

To implement the calculated attribute get-method you don't have to loop over the node. Just write

String value = element.getRecommendedActionsTravel();
if ( "Change Travel Request".equalsIgnoreCase(value) )
  return WDTextViewSemanticColor.CRITICAL;
if ( "***Request Cancellation***".equalsIgnoreCase(value) )
  return WDTextViewSemanticColor.MARKED1;
return null;

Dear Armin,

You are right. My context is like as follows:

MyOpenTrips (node)
+ color (TextViewSemanticColor, calculated=true)
+ recommendedActionsTravel (string)

Many Thanks. The issue got resolved using your code.

Hi Experts,

I have modified code like as below. However the issue still persists.

public com.sap.tc.webdynpro.clientserver.uielib.standard.api.WDTextViewSemanticColor getMyOpenTripsColor(IPrivateList_trips_appView.IMyOpenTripsElement element)
  {
    //@@begin getMyOpenTripsColor(IPrivateList_trips_appView.IMyOpenTripsElement)
	Collection openTrips = new ArrayList();
	for(int x=0; x<wdContext.nodeMyOpenTrips().size(); x++){
		IPrivateList_trips_appView.IAllMyTripsElement i = wdContext.createAllMyTripsElement();
	  if(wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel().equalsIgnoreCase("Change Travel Request")){
		  wdComponentAPI.getMessageManager().reportSuccess("i "+ wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel()+ "  trpno "+ wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getTripNumber() );
		openTrips.add(i);
		 return WDTextViewSemanticColor.CRITICAL;

		}
	   if(wdContext.nodeMyOpenTrips().getMyOpenTripsElementAt(x).getRecommendedActionsTravel().equalsIgnoreCase("***Request Cancellation***")){
		  wdComponentAPI.getMessageManager().reportSuccess("j");
		openTrips.add(i);
		return WDTextViewSemanticColor.MARKED1;
		}
	 }
	return null;

wdComponentAPI.getMessageManager().reportSuccess returns:

i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427 
 i Change Travel Request  trpno 1427

When I am removing "return null; " the code does not get compiled. I am getting following message "This method must return a result of type WDTextViewSemanticColor"
