Documentation: how to set a default parameter for all components of same type

1) Environment

• PrimeFaces version: 8.0
• Application server + version: jetty (primefaces-test project)

2) Expected behavior

If I select 23/04/2020, that should be the date submitted.

3) Actual behavior

However, the value submitted is 23/04/0020.

4) Steps to reproduce

Set locale to pt_BR, create a LocalDate variable and use it in a Calendar or DatePicker component.

…

5) Patch to reproduce the error with https://github.com/primefaces/primefaces-test:

[tandraschko]

we had a issue for creating a mechanism to allow default values, configured globbaly in the application for each attribute for each component thats a better way to go

[melloware]

@hfluz that is not a bad idea. Somthing like…

	<context-param>  
		<param-name>primefaces.DEFAULT_DATE_PATTERN</param-name>  
		<param-value>dd/MM/yy</param-value>  
	</context-param>
