Well i got rid of Integer usage with this variable itemsPerPage within the page 
and component as well as any initializations and modeled initialization in the 
setuprender
Gallery.JAVA
    @SetupRender
    public void setupRender()
    {
        itemsPerPage = 50;
        try
        {
            collection = loadCollection(collectionType);
        } catch (Exception e)
        {
            logger.error("error loading data on collection gallery");
        }
    }

and the NPE still occurs

I added @Persist to the page

Home.JAVA
    @Persist
    @Property
    private int itemsPerPage;

and the NPE still occurs

any event centric referencing of this variable induces an NPE

?

Any help is appreciated.

:(
