Does SelectItem value have to be a string?
I have the code pasted below, and I get the following error
javax.servlet.ServletException: Value is no String
(class=java.util.ArrayList, value=[[2820] three, [2821] emi, [2822]
emi_uk, [2823] itn, [2824] abc, [2825] ae, [2826] boomchicago, [2827]
chillitv, [2828] comedytime, [2829] criticalcontents, [2830] disney,

teamtalk, [2843] tvnewmedia, [2844] bbc, [2845] weatherchannel, [2846]
offthefence, [2847] zonemedia]) and component reportForm:cpvaluewith
path: {Component-Path : [Class:
javax.faces.component.UIViewRoot,ViewId:
/jsp/reports/reportGenerator.jsp][Class:
javax.faces.component.html.HtmlForm,Id: reportForm][Class:
org.apache.myfaces.component.html.ext.HtmlSelectOneListbox,Id:
cpvalue]} does not have a Converter
javax.faces.webapp.FacesServlet.service(FacesServlet.java:152)
org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:144)
rhythm.marketplace.filters.SessionFilter.doFilter(SessionFilter.java:69)
rhythm.marketplace.filters.AuthFilter.doFilter(AuthFilter.java:152)
So Is f:selectItems valid when I give it a List<SelectItem> when the
SelectItem is constructed with an Object and a String?
It takes in an object not a String, so I assumed this would be valid.
Thanks

Re: Does SelectItem value have to be a string?
Posted by Andrew Robinson <an...@gmail.com>.
Since the value is taken from HTML, it has to be represented as a
string on the client. To do this you must use a converter on your
listbox to convert to and from the object.
