Problem with remote panel and Visible property node -Gives GPIB error?

[Nacree]

I have a problem with my VI when controlling with a remote panel.  The VI works fine until the remote user releases control of the VI, at which point I get this error:

"Error 1 Occurred at Property Node In 020107.VI

Possible Reason(s):

An input parameter is invalid.

NI-488 Command Requires GPIB Controller to be Controller in Charge.

I am not using GPIB anywhere in the VI. 

Anyone have any ideas?

Thanks,

Nathan

With error code 1, you have two possible causes of the error. The first possibility is the invalid invalid parameter and the second possiblilty is the GPIB error. Since you are not using GPIB and the error occured at a property node, my guess is that you have an invalid parameter for the property node.

What is the property node and what are are the values you are using?

I am using the Visible property node to selectively display and hide clusters of contols and indicators.  I actually get an error for every property node that changed since control of the vi was released.

The VI works fine until the user released control or closes the web browser in which case the errors show up on the host machine.

This is a VI that is running on the host machine and not a built application running on the host machine.

If I have to re-do my whole program to not use any property nodes It will be a lot of work and some of the user-friendliness will be lost.

Thanks for any insights,

We are having the same issue with the Remote Panels.  Occasionally when a user using remote panels releases

control of the panel the LabView program crashes with an Error 1 code at some of the property nodes.

Some of the property nodes are writes and some are reads.  Which one it errors on differs each time.

We are currently using Labview 8.2.1.  The program was originally written in Labview 7.0.  We did not

have this problem in 7.0.

I have been progressively removing some of the "offending" property nodes, but LabView just errors out with a

code of 1 on a different property node.

I believe there is a bug in the NI code for the remote panel somewhere.

If anyone knows a good workaround I would appreciate it.

Thanks in advance for any help,

Hi Steve,

Is there any error text that accompanies this error 1?

Also, which property nodes are you using where this occurs?

Best regards,
