Crash on addition of new to many object about coredatalibrary

[GoogleCodeExporter]

Is this in the project as downloaded from the site or did you make any changes? 
 If you made changes, could you 
ZIP up your project/code and send to me?

thanks!

No, this is as is from the website. The file CoreDataSampleFor436 project, as 
well as a project I tried to start has 
this same problem. I am comparing your code with a similar project I am using 
to see if I can help.

I took that attached file and opened the XCode project just to make sure and 
followed these steps:

1) Clean all targets
2) Reset simulator
3) Build and Run in 3.1.3 iPhone Simulator
4) Click on the first row "Widgets"
5) Click on widget C
6) Click on Edit 
7) Click on Add Process
8) Select 1 process (also tested with > 1)
9) Press save

I don't get a crash.  I didn't try this on device right now, but I have in the 
past with success.  Are you following 
these steps and getting a crash or is there a different procedure you are 
following?  I attached a screenshot of 
the detailView.plist I am using - it is unmodified from the code you attached 
above.

What OS / XCode versions?

Weird. I did the same thing and I get a crash both in the simulator and on my 
device. 

OS 10.6.3
XCode 3.2.3

I'd love to get other people to try this, because we shouldn't be getting such 
different results.

can you enable the breakpoint objc_exception_throw and give me the backtrace?

aha... I noticed the crash occurs when you click on the green "add" button. 
When you tap the cell itself, the add 
function works just fine.

Found the problem - I forgot to check the type of editingStyle in the 
commitEditingStyle... method, so when you 
clicked the plus it was running the delete logic - just released .11 that fixes 
so that when you click the plus icon, 
its the same as selecting the row.

Thank you for the report.

Changed files are attached or in downloads.
