Like chuck said, you need to use AjaxHyperLink, AjaxUpdateLink or
AjaxSubmitButton for Ajax stuff.
Link the actions to your code, launchAlertDialog seems already OK.
If you want to replace the current page with a component inside an Ajax action,
you need to return an ERXRedirect with the desired new page specified like this:
ERXRedirect redirect = pageWithName(ERXRedirect.class);
redirect.setComponent(newPageToDisplay);
return redirect;
Often, you only want to update an AjaxUpdateContainer (or more than one) with:
AjaxUpdateContainer.updateContainerWithID(containerID, context());
AjaxUpdateContainer.updateContainerWithID(container2ID, context());
