Hi, I want to put Objects (DTOs) in my SelectItems, to be able to submit it in the Save, but i always get the Error Value is no String error from the renderer.
java.lang.IllegalArgumentException: Value is no String and component userForm:groupListBox does not have a Converter at org.apache.myfaces.renderkit.RendererUtils.getConvertedStringValue(Rende rerUtils.java:670) at org.apache.myfaces.renderkit.RendererUtils.getConvertedStringValue(Rende rerUtils.java:688) at org.apache.myfaces.renderkit.html.HtmlRendererUtils.renderSelectOptions( HtmlRendererUtils.java:459) <SNIP LONG TRACE> javax.faces.FacesException: Value is no String and component userForm:groupListBox does not have a Converter Does anybody have any idea what could be wrong here? I thought I could put any type of object in my SelectItem... Thanks, Greg
