Problems with {{ form.my_field.errors }} in oTree Lite

[Daniel Frey]

Hello everybody

I found a problem with the formfields using IntegerFields with choices.

I created a survey-question with 10 different options in  as follows: 

class Player(BasePlayer):
  risk = models.IntegerField(widget=widgets.RadioSelect,
    label="Please indicate your answer on the following scale: 1 means: not at all willing to take risks, 10 means: very willing to take risks.",
    choices=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10])

I want to present the choices in a html-table, like this:

If I test it, a message on the Debug info appears:

The form field risk has errors, but its error message is not being displayed, possibly because you did not include the field in the page. There are 2 ways to fix this:

1. Include the field with the formfield tag, e.g. {% formfield "risk" %}
2. If you are not using formfield but are instead writing the raw HTML for the form input, remember to include {{ form.risk.errors }} somewhere in your page's HTML.

As I'm not using the {% formfield 'risk' %}-tag, I included {{ form.risk.errors }} in the html-page.

Then, something very weird happens: At the place I included the error (right at the end, after </table>), two brackets appear on the html-page: 

I believe this is a bug in the latest oTree version, right?
