Bubble Event and System Forms

Question

Hi together,
I have a problem with using the BubbleEvent in combination with System-Form-Events:
Target:
If someone CLICK on the OK-Button in Systemform "134"
(Business-Partners-Form), I want to stop the Form being closed.
Concept:
using the Item-Event "et_ITEM_PRESSED" and set the BubbleEvent-Flag to false.
Sample-Code:
If (pVal.EventType = SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED) And _
           (pVal.FormMode = SAPbouiCOM.BoFormMode.fm_OK_MODE) And _
           (pVal.FormTypeEx.Equals("134") = True) And _
           (pVal.ItemUID.Equals("1") = True) And _
           (pVal.BeforeAction = True) Then
            Try
                BubbleEvent = False
            Catch ex As Exception
                'check Errors
            End Try
        End If
Problem and Test:
Nevertheless the form is being closed. The BubbleEvent-Flag has no effect. As I read in other topics, the 2005 Environment only accept the Bubble-Event in BeforeAction.
Three Events will be fired (Click on OK-Button):
et_Click | beforeAction = true
et_Click | beforeAction = false
et_Item_pressed | beforeAction = true
I have used the last Event (Item_pressed). Using the et_Click with beforeAction = true has also no effect.
The events will always be used individually at the test, not combined.
Maybe someone can resolve this problem...
Best regards
Jochen

Answer 1

Strange. I implemented a very simple add-on with B1DE
and added this listener:
    public class Button__134__1 : B1Item {
        public Button__134__1() {
            FormType = "134";
            ItemUID = "1";
        [B1Listener(BoEventTypes.et_ITEM_PRESSED, true)]
        public virtual bool OnBeforeItemPressed(ItemEvent pVal) {
            Form form = B1Connections.theAppl.Forms.Item(pVal.FormUID);
            Item item = form.Items.Item("1");
            Button button = ((Button)(item.Specific));
            // ADD YOUR ACTION CODE HERE ...
            return false;
As you can read this listener set the bubble event to
false for the button 1 in Form 134. The form cannot be
closed, the event is handled correctly by the add-on. I am
using 2005 SP1 but I guess it should be working the same
for your release too.
