Uploading a File using LazyDynaBean causes ClassCastException
-------------------------------------------------------------
Key: STR-3081
URL: https://issues.apache.org/struts/browse/STR-3081
Project: Struts 1
Issue Type: Bug
Components: Core
Affects Versions: 1.3.9
Reporter: Niall Pemberton
Assignee: Niall Pemberton
The changes to RequestUtils associated with STR-487 cause my application to
throw "java.lang.ClassCastException: java.util.ArrayList"
http://svn.apache.org/viewvc?view=rev&revision=524895
I use LazyDynaBean which returns Object.class as the property type of any
property which is not defined (since null would indicate no property and one of
the "lazy" features is to add properties automatically on "set"). Theres a bug
in the changes for r524895 which is using the Class's isAssignableFrom() method
the wrong way round:
propertyType.isAssignableFrom(List.class)
The above will return "true" when propertyType is "Object.class" - and so a
List is created which my application is not expecting (it expects a FormFile).
I believe the above will also fail if the property type is an ArrayList which
is also not desirable - correct code should be:
List.class.isAssignableFrom(propertyType)
