New issue 192 by geoff.ba...@gmail.com: "Select From List" keyword fails in
the presence of a horizontal scroll bar
http://code.google.com/p/robotframework-swinglibrary/issues/detail?id=192

Run the attached script on the program provided. It gets stuck in a loop
constantly trying to scroll leftwards, eventually failing with an exception:

$ env CLASSPATH=swinglibrary-1.1.3.jar jython ./testscript.py
Using org.netbeans.jemmy.drivers.DefaultDriverInstaller driver installer
Traceback (most recent call last):

java.lang.RuntimeException: java.lang.RuntimeException: Scrolling

The reason appears to be a bug in Jemmy, which is apparently trying to
scroll outside of the event dispatch thread. If I explicitly run the
keyword in the EDT (see commented code in testscript.py) it works, but for
most purposes I don't have to explicitly run keywords in the EDT.

I am using RHEL5 linux, SwingLibrary 1.1.3 and JVM 1.6.0.26

Since the root cause is a bug in Jemmy, I wonder could we upgrade the
bundled Jemmy version to the latest one and see is the bug fixed. If the
bug still exists, it should be reported to Jemmy's tracker.

Good news related to this is that Jemmy project seems to be more active
than when I looked last time. Its home isn't under netbeans.org anymore but
instead at http://java.net/projects/jemmy

Bad news related to upgrading the bundled Jemmy is that the version we
currently use is, AFAIK, pretty old compared to the latest Jemmy version
and there may be API changes.

The Jemmy project appears to have produced something called JemmyV2 now,
which certainly sounds like it might have API changes...

Are you sure the Jemmy people will actually fix bugs? They appear to be
replying on their mailing list now, but activity in the bug tracker shows
no bug being fixed or even acknowledged since 2009 although several have
been reported since then. That timescale isn't very useful to us, or to you
I suspect :)

Note that of the 6 issues my colleague Daniel and I just reported, I would
guess probably 5 of them are actually Jemmy issues, so this decision
impacts all of them.

keyword fails in the presence of a horizontal scroll bar

I fixed this by explicitly running ListOperator.selectItems in EDT, as
suggested in the testscript by Geoff.
