[dairav123]

<pe:layoutpane> closbale attribute not working. Am using primeface extensions version 6.2.4.

Getting below error in browser console,

TypeError: b is undefined layout.source.js:6710:17

Can you provide a fully working sample using the following Test project: https://github.com/primefaces/primefaces-test

Simply clone that project and create the smallest working example.
