Hello All,

I am new to JSF and am having an issue with a selectonemenu component always being null. I have form that is is populated with backing bean list that has the states. On the form the list displays properly. However when I attempt to write the value to the database, I get a null value.


Backing bean with list:



jsp view page:


selectedState method:

Hello Omar,
it seems that states_ isn't null, maybe you instatiated it and it is empty? Check for (states_!= && states_.size() < 1)

What I noticed in my code is that I initialized state_ to null. So I corrected that and am now getting another error. The error I am getting is Caused by: java.lang.NoSuchMethodError:

Here is a copy of the class I am using:

When I am calling the getSelectedState method from the bean I am getting
Caused by: java.lang.NoSuchMethodError: stateBean.getState()Ljava/lang/String;

I was able to get my code to run partially correct. However I am still having an issue binding the selectonemenu item that is selected from the jsp view to the information in the bean. Again, forgive my ignorance as I am new to JSF, 1st project btw, but I thought if used the value element in the selectonemenu component tag, then the value the user selects would be bound by the get and set methods of the underlying bean.
