Disappearance of Event

[Former Member]

Hi,

I have a Table with 5 static columns and a few dynamic columns lets say A, B and C. When a user clicks a particular row of the table and clicks a button, I want to show a dialog box, the following values as a radiobutton group:

(RB1) A

(RB2) B

(RB3) C

In order to do this, I created an event in Component Controller <b>ButtonSelectedEvent</b>, a method <b>fireButtonSelectedEvent</b> and event handler in dialog box <b>handleButtonSelectedEvent</b>. When the button is clicked, the action method fired is <b>onActionButton</b>.

I want to pass multiple values from method onActionButton to handleButtonSelectedEvent; therefore, I used ArrayList as a parameter for the event ButtonSelectedEvent, method fireButtonSelectedEvent and event method handleButtonSelectedEvent. However, the method fireButtonSelectedEvent is not visible in the method onActionButton. If I make the parameter as string(or for that matter any simple dictionary type), I am able to see the <b>fireButtonSelectedEvent</b> in the method <b>OnActionButton</b>.

When I say, I am able to see, this is what I mean..

wdContext.wdGetMyCompController.fireButtonSelectedEvent();

does not give an error as the method is visible.

I am on WAS 6.40 SP12.

Any light on this , is highly appreciated.

If you have not understood any part or any part that is not clear, do let me know, I will do the needful.

Hi,

Let me put my understanding first...

1) You have a button with action name onActionButton.

Inside the button action u r giving ur confirmation dialog.

2) For this confirmation dialog u r having an event handler by name handleButtonSelectedEvent.

<i>why do u want to have ur eventhandler in the controller instead in view?</i>

Now u want to pass the parameters to this event.<i><b> If the eventhandler is in the same view then it is possible to send set of parameters in an array or a bean, provided declare ur array or bean inside ur global declaration area.</b></i>

//@begin

//@end

Set the values to the array or bean inside the button action itself.

I think u cannot pass the parameters directly to the event handler.If u pass also u get null values.

Try giving globally and then check if it works.

Hi Nagarajan,

Thank you for immediately replying to my query.

The eventhandler handleButtonSelectedEvent is in the dialog box as mentioned in my earlier post. When I mean dialog box, I meant the view of the dialog box.

I am also referring to tutorial <b>Dialog Boxes in Web Dynpro Applications</b>.
