After using openassets issue_asset() , the asset quantity is 0 I am using openassets protocol issue_asset() function. After using the function, i call list_unspent(). The asset quantity field is all zero (see below). It means the issue_asset() function does not generate any assets. I have checked the return value of issue_asset(). It returns a valid transaction. Is there a reason why assets are not created?

The list_unspent() output is copied below:

I also called get_balance(). The output is listed below. The is no assets too.


Balance [{"address"=>"n3hqP9u5kQydyqGcPy3NHcEWnzBKJnv3aX", "oa_address"=>"bXDfidKiRDtsKr5RySb9YwU968bMVMnf8Zr", "value"=>"0.00433888", "assets"=>[], "account"=>""}]
The problem is after issue_asset(), if the min_confirmation is 1, we have to mine the bitcoin block for one time. Then only after that, the asset can be seen in get_balance.
