JSF Primefaces selectonemenu prints object hash in list

Question

I am having a problem with selectonemenu, it seems to be all working fine but the component returns object value hashes instead of the actual values themselves. The below i provide a screen shot and backing bean with xhtml code

Thanks for your help in advance!

you should change f:selectItems like below:

<f:selectItems value="#{categorycontroller.categoryList}"
    var="category" itemLabel="#{category.name}" itemValue="#{category.id}" />

Thanks for your comment I went for your solution. How about I want to get the selected items id number? – Tugrul ASLAN Sep 18 '14 at 07:03
well, that's a different question. you should use a converter for that. take a look at here please: http://www.mkyong.com/jsf2/custom-converter-in-jsf-2-0/ – tt_emrah Sep 18 '14 at 07:05
Thanks! I have found out a different way, when I use categoryName i can get acquire the value, I've already set it in xhtml file – Tugrul ASLAN Sep 18 '14 at 08:32

<f:selectItems value="#{categorycontroller.categoryList}" />

The above line returns each category object

Category class might have holding variable like categoryName and categoryValue.

You have to loop through using <ui:repeat>

<ui:repeat var="categoryVariable" value="#{categorycontroller.categoryList}" varStatus="status">
  <f:selectItem itemLabel="#{categoryVariable.categoryName}" 
                 itemValue="#{categoryVariable.categoryValue}"/>
   </ui:repeat>

As long as you can't answer workable code off top of head, please test code first before doing off as an answer. This code ain't gonna work. – BalusC Sep 18 '14 at 07:04
