Migrating extension to 10.1

[GhassanKarwchan]

I am migrating 9.3 Desktop extension to 10.1

I am getting this bug when I am trying to update a row in the geodatabase

"Cannot call Store on a recycled row while editing"

And seems the reason is, I am doing recyclable search like this

eatCursor = featLayer.Search(spatialFilter, true);

So, I changed it to false recyclable.
And it worked.

But my question is why 10.1 is not able to update recycled row, where 9.3 was able to?
what the reason of this change?
Is there any reason 10.1 disabled this feature?

It's because ESRI fixed a bug.  Editing a row from a recycling cursor may not have thrown an exception at 9.3 but it was never something you should have been doing.
