The line no 346 represents:

IWDConfirmationDialog dialog = wdComponentAPI.getWindowManager().createConfirmationWindow(dialogText,controllerInfo.findInEventHandlers("ok"),"ok");

Hi Amit,

Event handler name "ok" is case-sensitive. Check whether you are giving right name (and case) in both places in event handler's method signature and in method call controllerInfo.findInEventHandlers().

IWDControllerInfo controllerInfo = wdControllerAPI.getViewInfo().getViewController();

String dialogText = "The email was successfully sent!";

IWDConfirmationDialog dialog = wdComponentAPI.getWindowManager().createConfirmationWindow(

dialogText,controllerInfo.findInEventHandlers("ok"),"ok");

dialog.addChoice(controllerInfo.findInEventHandlers("newEmail"), "new email");

dialog.open();

i wrote this code but it's giving me "java.lang.NullPointerException " error.

have you created event handler with name "ok"..if not do that!!

similarly event handler "newEmail"

Hi,

You need to have events with names ok and newEmail. Remember it should be exactly same. And in these event methods you can put your code what you want to do on click of ok and new mail.

I think you have not defined these methods.

Change the first line of the code to:

IWDControllerInfo cont = wdControllerAPI.getControllerInfo();

May be your controllerInfo is null.

Hi,

Just assure that you have created the event handler with the same name under Methods tab (keep case sensitivity in mind).

Hi Amit,

IWDControllerInfo controllerInfo = wdControllerAPI.getViewInfo().getViewController();

String dialogText = "The email was successfully sent!";

IWDConfirmationDialog dialog = wdComponentAPI.getWindowManager().createConfirmationWindow(

dialogText,controllerInfo.findInEventHandlers("ok"),"ok");

dialog.addChoice(controllerInfo.findInEventHandlers("newEmail"), "new email");

dialog.open();

i wrote this code but it's giving me "java.lang.NullPointerException " error.

Have you created the event handlers for ok and newEmail

Hi,

1. Create 2 eventhandlers named "Yes" and "No" under Methods tab.

String dialogtext = "Are you sure you want to delete?";

IWDEventHanlderInfo eventhandler = wdControllerAPI.getViewInfo().getViewController().findInEventhandlers("Yes");

IWDConfirmationDialog dialog = wdComponentAPI.getWindowManager().createConfirmationWindow(dialogtext,eventhandler,"Yes");

eventhandler = wdControllerAPI.getViewInfo().getViewController().findInEventhandlers("No");

dialog.addChoice(eventhandler,"No");

dialog.show();

Hi,

Following is the usage

IWDConfirmationDialog dialog =wdComponentAPI.getWindowManager().createConfirmationWindow(confirmationText, action, label)

@param confirmationText - the text which is displayed inside of the dialog

@param action - the action which is fired, if the representing button is pressed in the dialog.

@param label - the label of the representing button
