SelectItems Rendering problem

[ldr <ch...@niro-it.dk>]

I dont know what Im doing wrong, but when I want to show my created
selectitems the rendering fails - nullpointer. There is nothing wrong with
the creation, that is there are no error and the structure and data looks
fine. I have below added my code and errors and hope that there are someone
who can see what Im doing wrong...

Creation code:
phoneBrands = local.getPhoneBrands();
// Create group items
supportedPhonemodelsMenuItems = new SelectItem[phoneBrands.size()];
Iterator iterBrands = phoneBrands.iterator();

for(int i = 0;iterBrands.hasNext();i++)
{
PhoneBrand tmpBrand = (PhoneBrand)iterBrands.next();
List tmpPhoneModelsBrand = local.getPhoneModels(tmpBrand);
Iterator iterPhones = tmpPhoneModelsBrand.iterator();

SelectItem[] brandPhones = new SelectItem[phoneModels.size()];

for(int j = 0; iterPhones.hasNext(); j++)
{
PhoneModel phone = (PhoneModel)iterPhones.next();
Integer id = ((Long)phone.getId()).intValue();
brandPhones[j] = new SelectItem(id, phone.getName());
}

supportedPhonemodelsMenuItems = new
SelectItemGroup(tmpBrand.getBrandName(),"desc",false,brandPhones);
}
