SelectItem getValue type problem
--------------------------------
Key: MYFACES-1382
URL: http://issues.apache.org/jira/browse/MYFACES-1382
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 1.1.3
Environment: Tomcat 5.0.28
Reporter: Alois Vitasek
Priority: Minor
Sorry for my english please.
I am using list of SelectItem objects to fill data in listbox. Listbox is using
an converor.
SelectItem object has method getValue, which returns a type Object.
In my case is type of the value property an Integer.
In class
javax.faces.component._SelectItemsUtil
is method matchValue which is testing if value of the componet exists
in set of values in the listbox. Listbox contais "raw values", value in listbox
is converted.
The code is
Object itemValue = item.getValue();
if(converter != null && itemValue instanceof String)
{
itemValue = converter.getConvertedValue(context,
(String)itemValue);
}
if (value==itemValue || value.equals(itemValue))
....
If in listbox are values not in type String (for example Integer), convertor is
not
invoked and following test will fails and application will end with validation
error exception.
This problem can be solved if only Strings are used as value in listbox which
are using
convertors. (trap ?)
Or change this code to something like this:
Object itemValue = item.getValue();
if(converter != null)
{
itemValue = converter.getConvertedValue(context,
itemValue.toString());
}
Or not allow to use no String value in a SelectItem object.
