an error when calling stored procedure

[jeun91]

hello, I'm using this great app thank to you.
recently, I got a problem when I tried to use the stored procedure.
error code is 1312 and error message is 'can't return a result set in the given context'.
I tried to use the procedure in another tools (ex. mysql workbench, heidiSQL, etc.) and it worked perfectly. the procedure is even simple one. is it bug? is there any solution to fix it?
