"The special value zero (0) indicates no limit",I don't want this,because there is a change status in the page,I will list the uploaded attachment,if the number exceeds the limit,I will use this function setFileQueueLimit(0),in this case,users should not upload attachments,but we seem to not have such an interface.

In that case you should set the button to disabled.
But you are right. Upon reflection we see that we shouldn't have used special values.
