remote control release cause property node error?

[RogerLu]

After using the web publishing tool to publish a VI, I can remotely view and control by another PC by a web brower. For the remote control, there's an icon on the right-top , I can request control of VI by right click the icon, also, release control of VI.

The problem is that when I release the control, there is an error 1 occured on the server. The error is:

Error 1 occurred at Property Node in Main.vi

Possible reason(s):

LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.

I noticed that this error occurred on the property node no matter is value or color, and this error only happens when the remote control user release the control or close the web brower.

Anyone have the same problem?

what is the property node used for?  what property is it trying to change?

[RogerLu]

Any property node, no matter is read or write.

For example in the attachment, I have a ring control, and creat a value property node for it, connect to a indicator.  Run this VI, I select "a" for the ring control, the indicator shows "a", I select "b", the indicator shows "b". Publish this by using Web publishing tool, request control of VI, make some changes of the ring, everything is OK, release contro, error occurred on the server.

I am using LabVIEW8.5
