Primefaces BlockUI not working

StackOverflow https://stackoverflow.com/questions/21774413

Question

In my JSF form, I am using BlockUI to show the busy status while processing. It worked fine until I add javascript to the header. With the script tag, the BlockUI is not showing at all. How can I work around this? Following is my form with the javascripts in which blockUI is not working. I am using JSF 2.2, Primefaces 3.4.2 in Glassfish 3.2.2 and firefox browser.

Solution

In your XHTML 

<script src="js/jquery.min.js"></script>

PrimeFaces already ships with jQuery bundled, yet you've downloaded and installed another one which would only conflict with PrimeFaces bundled jQuery.

Remove above line i.e <script src="js/jquery.min.js"></script>

Try above and see if that helps.
