In model project.scrum.us description_short always Null

[lesdekock]

I modified the src as follows:
FROM:
@api.one
def conv_html2text(self): # method that return a short text from description of user story
for d in self:
d.description_short = re.sub('<.>', ' ', d.description or '')
TO:
@api.one
@api.depends('description')
def conv_html2text(self): # method that return a short text from description of user story
for d in self:
#d.description_short = re.sub('<.>', ' ', d.description or '')
d.description_short = re.sub('<[a-zA-Z/][^>]*>', ' ', d.description or '')
