The events mouseover and mouseout are fired when the mouse enters/leaves the element where the event handlers are registered, and any nested elements which do not handle these events (because of event bubbling ). The events mouseenter and mouseleave are fired only when the mouse enters/leaves the specified element. Nested elements do not come into play. This following is a test page. You need Firebug to view the console output. Or use the JavaScript Executor bookmarklet. If none of these are available, an alert will popup (but you won't be able to fully test with alert.).

In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template.
Starting from the simple facelet example , make these additions:
Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...
Add a page for the about tab ( about.xhtml ):

<ui:comp...
Add a page for the partner tab ( partner.xhtml ):

Build and re-deploy the application. Launch the browser and load page http://localhost:8080/facelet-demo/about.jsf .

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

which can be easily dismissed as "input is invalid base64 encoded" or "partial input". But I know it's valid base64 encoded input!
The problem was, the input was base64 encoded on Windows! The error goes away after converting to Unix format with dos2unix .

To remove new line characters from a file:
with tr :
tr -d '\n' < the-file.txt or
cat the-file.txt | tr -d '\n'
with sed :
sed ':a;N;$!ba;s/\n//g' the-file.txt or
cat the-file.txt | sed ':a;N;$!ba;s/\n//g'
The sed version is a bunch of commands to manipulate the register etc. Regex replace " s/\n//g " does not work because sed regex works on a single line.

The PHP function file_get_contents reads the entire contents of a file into a string, while the function file reads a file into an array.
file_get_contents('filename') is equivalent to implode('', file('filename')) :
<?php
