Value Help on Adobe Forms

Question

Hi,
I'm trying to implement one search help (F4 on sap) on adobe forms. I just do this process
For standard value help in Adobe forms:
1) In layout chose UI element 'Value Help Drop-down List' from WebDynpro Native Controls of Library Palette.
2) In Object pallete ->Binding tab, update Default binding with corresponding field .
For ex: You have context like below
-NODE
-FIELD(type LAND1)
In Default binding, $record.NODE.FIELD
since LAND1 is a standard type, you will get all the values in value table T005 in the F4 help
3) Make sure the 'Type' of the field in Object pallete ->Field tab is drop-down list.
But i can't see any action on adobe. May the properties of the the attribute field on context are wrong.
Anyone can help please.
Thank you.

This is the code that the program create:
                var processingValueHelp = ContainerFoundation_JS.getGlobalValue(event.target, "processingValueHelp");
                   if(processingValueHelp == false) {
                       ContainerFoundation_JS.setGlobalValue(event.target, "processingValueHelp", true);
                       this.rawValue = "";
                       this.clearItems();
                       ContainerFoundation_JS.SendMessageToContainer(event.target,
                                                                     "valueHelp",
                                                                     this.dataNode.somExpression.replace(/(xfa.?\.)(datasets.?\.)(data.*?\.)/, ""),
                                                                     this.rawValue,
                                                                     event.target.mouseX,
                                                                  event.target.mouseY);
What is suppose to change ?
Thank you
