Cannot edit saved forms

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a form that contains a spinner widget
2. Start a New Form and partially complete it (but don't mark as complete
3. Continue Saved Form and try to edit the previously saved form
4. Collect then crashes complaining that a Vector cannot be cast into a 
Selection

What is the expected output? What do you see instead?
Expected to be able to edit the saved form but the application crashed instead

What version of the product are you using? On what operating system?
1.1.7 Beta, 1.1.7RC1 and code in repository. This problem did not exist in 1.1.5

Please provide any additional information below.
After some debugging - I found that the application crashed in 
org/odk/collect/android/widgets/SpinnerWidget.java line 74 i.e.

71        // Fill in previous answer
72        String s = null;
73        if (prompt.getAnswerValue() != null) {
74            s = ((Selection) prompt.getAnswerValue().getValue()).getValue();
75        }

I managed to fix it with the following code (note - I don't understand the 
codebase at all so this should be considered to be a makeshift plug rather than 
a well though-out fix)

        // Fill in previous answer
        String s = null;
        if (prompt.getAnswerValue() != null) {
            Object o = prompt.getAnswerValue().getValue();
            if (o instanceof Vector)
                s = ((Selection)((Vector)o).get(0)).getValue();
            else if (o instanceof Selection)
                s = ((Selection)o).getValue();
        }

Closing this as it hasn't be reproduced.
