Summary0005969: Reading a readonly property raises an exception
DescriptionWhen reading a readonly property from a TJvPropertyStorage, an access violation occurs. This AV does not surface because the reading code is surrounded with a try ... except which swallows it, but it should be avoided nonetheless.

I think the problem can be solved by changing the method as follows:

procedure TJvPropertyStorage.LoadAnyProperty(PropInfo: PPropInfo);
    if (PropInfo <> nil) and (PropInfo.SetProc <> nil) then
      ReadProperty (AppStoragePath, GetItemName(PropInfo.Name), TPersistent(FObject), PropInfo.Name);
    { ignore any exception }

(The check PropInfo <> nil is new.)

I could have checked in the change myself, but I am not 100% sure whether it is correct, so I'd like somebody else have a look first.
TagsNo tags attached.
