[jira] Created: (MYFACES-1156) Model update uses empty string
instead of null. Custom String converter not possible.
Model update uses empty string instead of null. Custom String converter not possible.
--------------------------------------------------------------------------------------
Key: MYFACES-1156
URL: http://issues.apache.org/jira/browse/MYFACES-1156
Project: MyFaces Core
Type: Improvement
Versions: 1.1.2-SNAPSHOT
Environment: Windows XP SP2, Tomcat 5.5, Myfaces 1.1.2-SNAPSHOT, Hibernate 3.1.2, Facelets 0.8
Reporter: Veit Guna
I've encountered a problem using String values with myfaces. The default behavior of myfaces (probably jsf?) seems to be, that Input values of type String
get converted to an empty String (""). Instead I would like to have a null value updated in my model. This is because I don't want to have
empty Strings in my DB - but nulls.

----------------------------------------
Resolution: Won't Fix
Unfortunately, this can't change until the JSF spec changes since the spec disallows custom String converters.
You can add your own comments on this matter to the following JSF issue.

------------------------------------
Sorry, I forgot to mention, that using a custom String converter doesn't work.
--cut here--
Class valueType = vb.getType(facesContext);
if (valueType == null) return null;
if (String.class.equals(valueType)) return null; //No converter needed for String type
if (Object.class.equals(valueType)) return null; //There is no converter for Object class
