[jira] Created: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"
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:
-------------------------------------------

[jira] Commented: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"
Posted by "David Brainard (JIRA)" <de...@myfaces.apache.org>.
[ https://issues.apache.org/jira/browse/MYFACES-1760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12540546 ]
David Brainard commented on MYFACES-1760:
-----------------------------------------
When we change the value binding from a list to an array this problem does not occur.ie in this value-expression "#{test_scope.targetPagePhysicals}" if targetPagePhysicals is an array this problem wont occur.
I checked the impl. The problem is that when the selected values are converted, the type of value binding is checked
valueType = vb.getType(facesContext);
and if it is an array the selected values are set in a array and if it is a list it is set to an arraylist.
so when getSelectedValues() method is called it just resolves the value and casts it to Object[] and we get the prob.
I have checked with the Sun RI. the prob is present there also.
I have checked the specs.this is wat it is stated in the specs.
"This property is a typesafe alias for the value property,so that the actual state to be used can be acquired via a value expression."
I think we have to check the type of the value returned by value binding before casting to Object[](Unless it has been implemented like that intentionally for some reason).
pls comment if there is any prob.

[jira] Commented: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"
Posted by "Simon Kitching (JIRA)" <de...@myfaces.apache.org>.

Simon Kitching commented on MYFACES-1760:
-----------------------------------------
The getSelectedValues method certainly assumes the value is an array:
public Object[] getSelectedValues()
{
return (Object[]) getValue();
}
Note that the spec for UISelectMany says: "Optionally, the component can be preconfigured with zero or more currently selected items, by storing them as an array in the value property of the component.". And the setSelectedValues method takes only an array as a parameter. This suggests that the value should always be an array (ie it would be an error to bind the value to an expression returning a list).
However currently methods compareValues and _createItemValuesIterator both try to handle values that are list types.
Guy, I presume that your value-expression "#{test_scope.targetPagePhysicals}" returns a List?

-------------------------------------
I am not familiar with JSF core code, but I don't think it is implemented like that intentionally, since it seems not reasonable accepting List as value, but failing when trying to get the selected values.

[jira] Commented: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"

-------------------------------------
Hi,
I think that the casting on the return is not mandatory:
return (Object[])((List)selectedValues).toArray(); ----> return ((List)selectedValues).toArray();

[jira] Commented: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"
Posted by "Simon Kitching (JIRA)" <de...@myfaces.apache.org>.
[ https://issues.apache.org/jira/browse/MYFACES-1760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12540802 ]
Simon Kitching commented on MYFACES-1760:
-----------------------------------------
Yes, but my point was that it is not clear whether the fix is to
(a) convert list to array in getSelectedValues, or
(b) report an error if the valueBinding points to a non-array. This error check would need to be done early (not just in getSelectedValues).
I agree the current setup is inconsistent.

David Brainard commented on MYFACES-1760:
-----------------------------------------
Sorry i missed a part:
the conversion logic according to the specs(docs in ri) and impl support only array or arraylist.
so the getSelectedValues() should support only those two " array and arraylist "(There wont be anything else coz they they are converted properly and set ;) . so any error will be thrown at that point itself so no need to wry)
so an else part should be added to the logic which will throw an error since we support only array or an arraylist .

[jira] Commented: (MYFACES-1760) Using "getSelectedValues" of
"UISelectMany" seems to be causing "ClassCastException"
Posted by "David Brainard (JIRA)" <de...@myfaces.apache.org>.
[ https://issues.apache.org/jira/browse/MYFACES-1760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12540814 ]
David Brainard commented on MYFACES-1760:
-----------------------------------------
this is wat the spec(jsf-1_2-spec) says about Selected values:
name :selected Values
Type : Object[] or array of primitives
Description : The selected item values of this component. This property is a typesafe alias for the value property, so that the actual state to be used can be acquired via a value expression."
according to this we have to just obtain the value from the value expression and return a primitive or an object[]
So according to me the logic should be as follows:
Obtain the value through value binding
if the value is an array
return the value casting it to Object[]
if the value is a ArrayList
convert the value to an array, return the array after casting it to Object[]
if this is acceptable pls comment i'l add a patch for this tom.
Regards,
David Brainard Sounthiraraj
