Property binding code doesn't like Map.Entry
--------------------------------------------
Key: STS-330
URL: http://mc4j.org/jira/browse/STS-330
Project: Stripes
Issue Type: Bug
Components: Validation
Affects Versions: Release 1.4.2
Reporter: Tim Fennell
Assigned To: Tim Fennell
Fix For: Release 1.5
The summary is merely an example. The actual case is that the code does not
deal well with the following scenario:
1. Stripes gets handed an instance of Foo
2. Foo implements a public interface, AnInterface which specifies public
getter/setter methods
3. Foo is actually a protected or private (inner) class
4. Stripes tries to get or set the property value of one of the properties
specified in the public interface AnInterface
The primary example is with Map.Entry, which is public and specifies accessors
for 'key' and 'value'. However, in the JDK all the implementations of
Map.Entry are non-accessible classes (usually private inner classes of their
respective Map implementations). The PropertyDescriptors handed back by the
JDK Introspector provide as accessor/mutator methods, the public methods of
these private classes which cannot be executed via reflection without an
IllegalAccessException!
I think there are two possible solutions:
1) if Introspector provides public methods that are not accessible, call
setAccessible(true) on them
2) Use the method names and parameter types and search up the hierarchy for a
public interface that specifies the method. Take the method from the public
interface and call invoke() on that.
I've verified that they both work. #2 is probably more correct, but is also a
lot more work (to code, and at runtime).
