Disclaimer: school project.
Hello,
I'm having a strange issue which has hold me back for days.
The project im working on is a car tracking and paying system.
I'm trying to add a web page to my project which adds a region with roads, or edits an existing region.
When adding only a region everything goes fine, The variables are taken from the form and the region is saved to the database. But when i add the code for selecting and adding the roads the buttons are not working anymore.
I found out that when i only remove the SelectOneMenu the page loads, and submits the region (withouth roads), but i couldn't find a mistake in the SelectOneMenu
I did research and found out that the problem is caused by a validation error when the button validates the form. Source 1: link
I tried to fix this problem by checking if i did anything wrong as said in source 2 but with no success:

Here the body code of the AddRegion.xhtml :
<body>
<ui:composition template="./Templates/AdministrationTemplate.xhtml">
<!-- side menu -->
<ui:define name="menu">
<ui:include src="./Templates/RegionMenu.xhtml"/>
</ui:define>

<!-- Region id for editing an existing region -->

So my exact question is: What am i doing wrong with the SelectOneMenu that makes the buttons in the form to stop working?
I'm sorry it is so much to read, Please ask if you require some extra explanation on the system.
I am using:
Netbeans 7.2.1
Glassfish 3.1.2
Primefaces 3.5
Any help/suggestion is very much appreciated :)
