I have a requirement where I need to populate the drop down content after user interaction. I'm populating the drop down using a4j, but again when I submit this form, for some reason, it seems it cannot read the or identity the data present inside the drop down....
<h:form>
.......
<h:selectOneMenu value="#{coreServices.selectSomething}" id="list" rendered="true">
<f:selectItems value="#{coreServices.selectListOfValues}" />
</h:selectOneMenu>
<a4j:commandButton action="#{coreServices.ListOfValues}" value="Get Values" reRender="list"/>
.....
</h:form>
The above code it working as expected, like when I click on action "Get Values" it is populating the drop down menu.
But again, when I select one of the values from the drop down and submit the page, I get following error. Can someone suggest, what I'm missing or doing wrong ?
java.util.NoSuchElementException
