Dead OutPoint encountered when sending transaction

[lostpg]

I am deploying a contract on the dev chain using the go sdk, with Go code here.

But when I was trying to raise a transaction, it failed with a log

2020/05/13 17:52:03 send transaction error: OutPoint: Dead(OutPoint(0x120803ff0f9891c2278f26d605f4e67e1b462a1a3ebbf0444ed17e74198920f000000000))
exit status 1

Maybe I made this error by using CellCollector wrongly. How can I get all live cells correctly?

It seems that this problem is caused by code here.

The JSON rpc get_cells_by_lock_hash returns live cells in block range [from, to], which means the cells in the block at height to are counted in.

While the code below will count in some cells twice as the for loop goes.

func (c *CellCollector) collectFromBlocks(lockHash types.Hash) (*CollectResult, error) {
        // omitted snippets 
	for {
		end := start + 100
                // omitted snippets 
		start += 100
	}
	return &result, nil
}

As for the solution, a slight change may work.

start += 100 // -> start += 101

@lostpg thanks, v0.2.2 already fixed this bug.
