stan_sfdc Passing Input Text Values from VF Page in Wrapper
I have two problems here -
1. When invoking Save, the value of Input Text of "Broadcast Number" is not getting sent to the controller, without removing the <apex:selectList>
2. When click on Next / Previous Page (in pagination); the values are getting reset

Also, because of the standardsetcontroller, your wrappered results are getting cached. So when you hit previous / next, it's loading the old state of the record. You'll either need to requery (and reset) the standardsetcontroller or use a different approach in order to get the most current value of your records.
