Hi,

Write this code in the "wdDoModifyView()" method:

//let's say the first button ID is btn1

IWDButton buttonOne = (IWDButton) view.getElement("btn1");

buttonOne.mappingOfOnAction().addParameter("commandID","btn1");

//let's say the second button ID is btn2

IWDButton buttonTwo = (IWDButton) view.getElement("btn2");

buttonTwo.mappingOfOnAction().addParameter("commandID","btn2");

Add the parameter "commandID" to the event handler of ur buttons and it should be of type "String". That will look like:

public void onActionTest(IWDCustomEvent wdEvent, String commandID){

//here commandID contains the ID of the button which was clicked

 wdComponentAPI.getMessageManager().reportSuccess(commandID);
}

A small correction - Put wdDoModifyView() code in

if(firstTime) { ...}

hi Suresh,

in your case no need to get id of buttons , you can open a window using

id but it will be a long process.

you just create a value attribute of type string

*let you have created value attribute named "myButton" *

now on every button click you set the value in myButton. like

wdContext.currentContextElement().setMyButton("your value");

now check value of button and write your desired code .

Hi,

Create a parameter to the action lets say id of type string

Do a source mapping as follows

IWDButton b1 = (IWDButton)view.createElement(IWDButton.class);
	  //In older verion use addParameter
	  b1.mappingOfOnAction().addParameter("id","Button1");
	  b1.mappingOfOnAction().setString("id","Button1");

//Do the same for rest of the buttons

This code is not correct: You create a button with an automatically assigned ID, but you pass "Button1" to the action handler. The correct code would be

IWDButton b1 = (IWDButton) view.createElement(IWDButton.class, "Button1");
b1.mappingOfOnAction().addParameter("id", b1.getId() );

wdDoModifyView(...)
{
  if (firstTime)
  {
    for (int i = 1; i <=5; ++i)
    {
      IWDButton button = (IWDButton) view.getElement("btn" + i);
      button.mappingOfOnAction().addParameter("id", button.getId());
    } 
  }
}

Or better: If you have an IDE that contains the parameter mapping editor, use it and don't write code.
