Hi, I'm building a warhammer online library for users. When i want to save a new model, i needed to select a race, modeltype and section from comboboxes. I do this lik this: <h:outputLabel value="Select a race for your model:"></h:outputLabel> <h:selectOneMenu value="#{saveModel.race}"> <f:selectItems value="#{saveModel.races}"></f:selectItems> </h:selectOneMenu> i have a field race in my session bean with a setter and getter and i filled the selectOneMenu by adding selectitems to them with a object of race in it. Now when i want to save it i'm doing this: <h:commandButton value="create model" action="#{saveModel.saveCurrentModel}" /> the problem is that he's not going in to that method and i get this output: sourceId=j_id4:j_id11[severity=(ERROR 2), summary=(Conversion Error setting value 'friesjes' for 'null Converter'. ), detail=(Conversion Error setting value 'friesjes' for 'null Converter'. )] sourceId=j_id4:j_id21[severity=(ERROR 2), summary=(Conversion Error setting value 'type1' for 'null Converter'. ), detail=(Conversion Error setting value 'type1' for 'null Converter'. )] sourceId=j_id4:j_id16[severity=(ERROR 2), summary=(Conversion Error setting value 'section1' for 'null Converter'. ), detail=(Conversion Error setting value 'section1' for 'null Converter'. )] ;|WARNING: FacesMessage(s) have been enqueued, but may not have been displayed. I can't figure out what i'm doing wrong... Any help? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197438#...
