Using findAll(): 'NoneType' object is not iterable? --- only one iteration possible!

Asked by Rhys

here is the message:
[profile] Finder.findAll START
[profile] Finder.findAll END: 497ms
[profile] Finder.findAll START
[profile] Finder.findAll END: 509ms
[profile] Finder.findAll START

and here is the code:
setFindFailedResponse(SKIP)
for x in findAll(img1 ):
 setFindFailedResponse(SKIP)
 click(x)
 wait(2)
 click(image2 )
 wait(2)
 while exists(image3 ):
  sleep(5)
for x in findAll(image1a):
 click(x)
 wait(2)
 click(image2 )
 wait(2)
 while exists(image3 ):
  sleep(5)

why is it that i am geting a 'NoneType' object is not iterable? error

If you want to iterate more than once thru your matches after findAll(), you have to save the matches into a list first.
An iterator can only be used once.

look: http://sikuli.org/docx/region.html#Region.findAll
and: http://sikuli.org/docx/finder.html#finder

I'm working in Jruby and have come across a similar problem. Basically I do a findAll e.g

myMatches = someRegion.findAll(somePattern)

If I call the "count" method on myMatches first then I cannot iterate through the matches later. It seems that the count method actually uses the iterator so I can't use it later!

Is this correct and how do I get the number of matches? Do I have to copy into an array first?

Thanks

Zubin

@Zubin
as mentioned in comment #1, every walk through the iterator makes it empty.
… count has to walk through, I guess.

Can you help with this problem?
