Olha sua mensagem de erro, você teve um NullPointer Exception.

O que tem nessa linha? at com.wave.erp.cadastro.controller.cadastro.ManterERPCliente.popularCliente(ManterERPCliente.java:360)

#3 
Long vendedorId =  hdCliVendedorId.getValue();
		if (vendedorId == null){
			cliente.setVendedor(null);
		}else{
			Vendedor vendedor = cliente.getVendedor();
			if (vendedor == null || !vendedor.getCdEmpresa().equals(vendedorId) ){
				try{
					vendedor = vendedorFinder.buscarVendedorById(vendedorId);
					cliente.setVendedor(vendedor);
				}catch(ObjectNotFoundException e){
					if (!screenSaver)
						throw new UserException(e.getMessage());
				}
			}
		}

Está na linha:
vendedor = vendedorFinder.buscarVendedorById(vendedorId);

#4

Seu vendedorFinder não está null? Você o instancia onde?

#5

Estava trabalhando com STS (Spring), e usando injeção de persistência, logo, havia esquecido de apontar a classe IVendedorFinder dentro do Objeto.
Por isso: NullPointerException .

Abraços.
