please help me i am stucking with problem last 15 days....

Please UseCodeTags--without them it's much harder to read code and configs.

15 days? That's amazing. I think I would have asked sooner.

You're providing a "name" for the combobox. S2 is trying to use that value to pre-populate the combobox. Your action doesn't have a fruitNames property, so it throws an exception. Create a fruitNames property.
