Bug Description

Using SikuliX 1.0.1 or lastest SikuliX 2014 1.1.0 nightly build 2014-12-09 on Windows 8.1 x64 with Java 1.7.0_72.

If you have a test which imports another tests and uses its images (I call them shared images),
first of all it won't show a preview of the shared images until the test was run in the IDE.
After the test was executed you can preview the shared images by toggling with Ctrl + T (two times).
Now if you click on a shared image to view it in the Pattern Window it will cause an NullPointerException
and the Pattern Window won't open.

Here is the trace back:

Again I cannot reproduce on OS X 1.1.0 with latest nightly 1.1.0 (1.0.1 might have these problems).

# main
import testImportSub
find("icon.png").highlight(2) # no thumbnail ever

# testImportSub
from sikuli import *
"icon.png" # thumbnail is shown from beginning and opens Preview

... sure you are really using the latest sikulix.jar from nightly 1.1.0?

I did a fresh install yesterday, see setup log:

And here my test scripts:
# main.sikuli
import sys, os
sharedPath = os.path.abspath(os.path.join(getBundlePath(), ".."))
sys.path.insert(0, sharedPath)
import shared
from shared import *
wait(Pattern("shared_image.png").exact()) # shows up after run and toggle twice with Ctrl + T

# shared.sikuli
from sikuli import *

I have opened only the main script, if this matters.

ok, thanks and understood.

On Monday I can test on Windows.

Did you found time to reproduce the bug?

In the meantime I found a workaround, see attached patch.

This means it is Windows special. I will check and fix.
