I have implemented the custom view scope for spring. The page was a redirect from another bean with prerenderView listener that loads a p:datatable. The datatable is loaded with the values and then there is a p:command button to submit the data to a backing bean that calls a service to use the dao implement to update a table. The daoImpl has none of the injected properties now. Datasource and jdbctemplate are now null. I believe I have everything configured to let Spring managed my beans but it seems to me a new instance of the bean is created and spring is not aware therefore doesn't inject the values. Code below has been simplified.
Page
<ui:define name="content">
<h:form id="form1" >

Adding this to web.xml and the datasource is getting injected everytime now. Not sure of the repercussions yet.

Although I didn't get this exception, I still had the break of injections that the answer describes.
