ISSUES
1. [New comment] UnboundName on invoking member for DynamicObject
http://ironpython.codeplex.com/workitem/35679
User MarkusSchaber has commented on the issue:
"<p>As far as I know, IronPython always uses TryGetMember, and then tries to
invoke what it gets there. This is according to the python semantics, where
member access and calling are two separate steps.</p><p>Maybe you can
appropriately override TryGetMember to support your use
case?</p>"-----------------
2. [New comment] Fail to display WPF window containing TreeView by Python script
http://ironpython.codeplex.com/workitem/35681
User MarkusSchaber has commented on the issue:
"<p>As far as I know, not at all.</p><p>In other words, the script executes
just in the thread which is calling ScriptSource.Execute(). (At least, as long
as the script itsself does not spawn other threads...)</p><p>But as this is an
user question and not a bug report, you should better ask it on the mailing
list instead of here.</p>"-----------------
3. [New comment] Fail to display WPF window containing TreeView by Python script
http://ironpython.codeplex.com/workitem/35681
User syang has commented on the issue:
"<p>Thank you MarkusSchaber for your response. ScriptSource.Execute() does not
try to access UI even though the Python script could creates a window and
display it to the user. Is there anyway to display a WPF window safely and
reliably? As the previous message stated, my case could display the window
correctly once. </p>"-----------------
4. [New issue] ValueError: Index was out of range. Must be non-negative and
less than the size of the collection.
http://ironpython.codeplex.com/workitem/35682
User s3e3 has proposed the issue:
"After installing IronPython 2.7.5b2 and later 2.7.5b3 we started getting
following exception very frequently while running our IronPython build scripts:
ValueError: Index was out of range. Must be non-negative and less than the size
of the collection.
Parameter name: index
Running some of our scripts multiple times with identical input parameters
gives very unpredictable results - sometime exception is raised (but almost
always in different places in code), sometime script run passes without
exception.
Prior to version 2.7.5b3, we used IronPython 2.7.3 and never had exception such
as "ValueError: Index was out of range..." running the same code that with
v2.7.5 throws this type of exception.
I am afraid it would be not very useful to provide any more details (code
samples, etc), because exception is thrown in various, seemingly totally
unrelated, places while running the same piece of code with identical input
parameters for every code run.
Exception message " Index was out of range. Must be non-negative and less than
the size of the collection." indicates that it is thrown from underlying .NET
platform, it is not native standard Python exception message.
Can someone please take a look at this issue - it is showstopper for IronPython
use in our company, as was some other bug in IP 2.7.4 that prevented us to
upgrade from version 2.7.3 that we still must use (due to regressions in newer
versions)."
