BadValueError: Property title is required

Hello,

I'm trying to create simple method to create category. I set the model
category:

class Category(db.Model):
title = db.StringProperty(required=True)
clashes_count = db.IntegerProperty(default=0)

And the class New Category as well :

class NewCategoryPage(webapp.RequestHandler):
def get(self):
categories = Category.all().order('-title')

template_values = { }
path = os.path.join(os.path.dirname(__file__), 'templates',
'category_new.html')
self.response.out.write(template.render(path, template_values))

def post(self):
category = Category()
category.title = self.request.get('title')
category.put()
self.redirect('/')

Here is the template:

{%extends "base.html"%}
{%block body%}

<h2>Add New Category</h2>

<form action="" method="post">
<div>Title: <input type="text" name="title" size="100" /></div>
<div><input type="submit" value="Publish"></div>
</form>

{%endblock%}

The problem is that I'm getting an error BadValueError: Property title
is required. Can you help me with that ? Thanks
