What steps will reproduce the problem?
1.run script :
  print self.current_element
  action_chains.drag_and_drop_by_offset(self.current_element, 330.5, 280).perform()

Please provide any additional information below. A sample reduced test
case, or a public URL that demonstrates the problem will intrigue our merry

more likely to look at your problem if you make it easy for them!

Hi!

I can not reproduce it for my Win7, selenium 2.35, chromedriver 2.3, chrome 29.
Could you recheck it with the latest chromedriver?

Also please provide exception for example from #c5

Hi!

The error "at least an element or offset should be set" is raised when 
chromedriver receives no "xoffset" or "yoffset" JSON parameter.

Could you check what question.location contains before executing of line:

action_chains.drag_and_drop_by_offset(answer, question.location['x'], 
question.location['y']).perform()

?

Also it'd be good if you investigate what JSON string python binding sends to 
chromedriver.

hi about what  contains in question.location from #c5:
print answer
print question
print question.location['x'] 
print question.location['y']
print type(question.location['x'])
print type(question.location['y'])

outputs:
<selenium.webdriver.remote.webelement.WebElement object at 0x02AAAEF0>
<selenium.webdriver.remote.webelement.WebElement object at 0x02AAAFB0>

Reproduced.

The problem is with float coordinate - chromedriver accepts only integers now.
Force converting was enabled in Python and Ruby bindings at rfc395f18551d

Original comment by a.u.savchuk on 12 Sep 2013 at 12:04

GoogleCodeExporter commented 9 years ago 
You could make force converting manually by:

question.location['x'] = int(question.location['x'])

as workaround.
