Ok, I think I figured out my problem. I'll summarize here in the hopes that this helps someone. I initially got the solution half right, by implementing a Converter to convert between the String representation of an Employee and an Employee object. However, I was still failing during the validation phase even though I had implemented a "null" validator that always returned. The problem is that the UISelectOne class has a "validateValue" method that attempts to validate that the selected item is in fact contained within the UISelectItems list. It does this by essentially calling java.lang.Object.equals() on the selected object to compare it against items in the list. Even though all the data fields within the Employee object instances were the same, they had different object references, and therefore were deemed to be different. This ultimately led to a failure during validation. In order to solve this, I had to implement an equals method of my own in the Employee class that overrides the default java.lang.Object.equals method. This equals method compared the data fields within two Employee objects and declared them equal if all fields were equal.
To summarize, if you want to populate a UISelectOne control with a list of objects that are not simple Strings, you need to do two things; implement a Converter to go back and forth between String and Object, and override java.lang.Object.equals with your own equals implementation that compares the Object's data fields. Hope this helps someone out there. Good luck finding this documented somewhere. -- View this message in context: http://www.nabble.com/JSF-Newbie-needs-help-with-selectOneMenu-and-valueChangeListener-tf4341404.html#a12484864 Sent from the MyFaces - Users mailing list archive at Nabble.com.
