And i tried to debug the related program (.org.libero.form.WOrderReceiptIssue.java)
After it run "result = Messagebox.show(Msg.getMsg(Env.getCtx(), "Update"),"",Messagebox.OK|Messagebox.CANCEL,Messagebox.QUESTION);"
but the message box was not showed to us to choose option and the value of results was set to 1 directly!
And it have the same error for message box "Is close document".
So when we tried to goods receipt, the order will always update and close manufacturing order.
As message box was not showed us to choose before it get value.
