How do i pass parameters or set fields of Managed Beans to get the proper side effects from the addAction?
My ManagedBean listaEntrada has a property that is reference, however I need to use the ProductController Bean to get the Description from the Entity Manager. Then I need to call the addAction of the listaEntrada Bean to add that product to the list of products.
My problem is how do I pass the Values that I get from the productController and set my listaEntrada controler fields
Is it possible/correct to do value=”#{listaEntrada.referencia}=#{productController.referencia}” ?
BalusC et all thanks for your replies, the project is shaping up thanks to your replies, and research on my part.
Note: I am currently using JSF but I will use Primefaces on the end product, hence the primefaces namespace.
