Using "getSelectedValues" of "UISelectMany" seems to be causing
"ClassCastException"
------------------------------------------------------------------------------------
Key: MYFACES-1760
URL: https://issues.apache.org/jira/browse/MYFACES-1760
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 1.1.5
Reporter: Guy Bashan
It seems like calling getSelectedValues method of selectBooleanCheckbox causes
exception.
This is an example for a fregment of code:
---------------------------------------------------------
<t:selectManyCheckbox
value="#{test_scope.targetPagePhysicals}" layout="pageDirection"
converter="PagePhysicalConverter" binding="#{test_scope.htmlSelect}">
<f:selectItems
value="#{test_scope.pagePhysicals}" />
</t:selectManyCheckbox>
<t:commandButton value="submitTargetPages"
style="width:100px" immediate="true" onclick="submit()" forceId="true"
actionListener="#{test_scope.targetPagesSelectedAction}" />
In the bean:
----------------
public void targetPagesSelectedAction(ActionEvent event)
{
Object[] xx = htmlSelect.getSelectedValues();
FacesContext.getCurrentInstance().renderResponse();
}
Causes the following exception:
-------------------------------------------
