Description

I was trying to clip dem by watersheds.
It was same process as below.

http://docs.qgis.org/2.2/ja/docs/training_manual/processing/iterative.html

But it doesn't work when it iterates.
Without iteration, I could clip my data.
I made sure that polygon(watersheds) and raster(dem) have same CRS.

I think this function is very useful for everyone.
Please give me some idea to fix this problem.
