Hi @all, i have a major problem using the jsf component
<h:selectOneMenu> with <f:selectItems>. I get the following error
message: javax.servlet.ServletException: Collection referenced
by UISelectItems with binding '#{formParameter.value}' and Component-Path :
{Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId:
/task.jsp][Class: javax.faces.component.html.HtmlForm,Id: taskform][Class:
javax.faces.component.html.HtmlDataTable,Id: _id2][Class: javax.faces.component.UIColumn,Id:
_id7][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: _id11][Class:
javax.faces.component.UISelectItems,Id: _id12]} does not contain Objects of
type SelectItem
It is the last part of the sentence that lets me get
confused: I have constructed an ArrayList with elements of SelectItem. If i
immediately test if the components in the ArrayList are instanceof SelectItem,
i get for all elements „true“. If i use the same ArrayList with the
<h:selectOneMenu> and <f:selectItems> jsf tag i get the error
above. I managed to put some System.outs in the myfaces impl api, so that i get
the items to standard out that cause the Exception above. The interesting thing
is, if i call (in the class SelectItemsIterator) item.getClass().getName() it
results in javax.faces.model.SelectItem on standard out. The class
SelectItemsIterator also tests instanceof with javax.faces.model.SelectItem,
but it results in false, so the Exception is thrown. Maybe someone can help - we are stuck in development
process. Many thanks, bye, Ingo ----------------------------------------------------------- Dipl.-Wirtsch.-Inf. Ingo Ott University of Mannheim IT Center | Chair of Information Systems III L15, 16 D-68131 Mannheim @Office +49 (0) 621 181 3162 Mobile +49 (0) 176 241 26216 Fax +49 (0) 1212
