Fact: Any window.open() call will be caught by the popup blocker which has been made without user interaction or executed by eval().

• OutputResource and DataExporter component difference:
  Both components use window.open(), but the difference is that the outputResource pre-renderes the resource path to the onclick attribute of the commandButton , so when user clicks on the button it directly makes the window.open() call which invokes a servlet and JSF Lifecycle never gets executed. While the dataExporter download link causes a JSF life cycle to be begin, during the lifecycle component creates appropriate file makes window.open() call using JavaScript context API, which obviously uses eval() that is why dataExporter caught by the popup blocker.

Seems like there isn't any javascript solution or technique.

New attribute added named as "popupBlockerLabel".

Tested on 1.8.2 build 6 + tomcat 6 using component showcase facelets-enh.

1. In Opera 10, Safari 4, and FF3.5, if the pop up blocker is on, the message "Popup Blocker detected - click here to resume download..." will show and resume the downloading successfully

2. in IE6, downloading will proceed regardless of the status of the pop up blocker

3. In IE7, downloading would not start unless the Ctrl key is held down at the same time. This happens regardless of the status of the pop up blocker as well.

Tld doc is verified having been updated in 1.8.2 build 6

Applied Ken's suggestion to handle IE6 and IE7.
