LabVIEW 8.2 - Custom Probe mystery behavior

[DonRoth]

Hi:

I recently updated code built in v7.1 to v8.2.  In one section, I have a simple wire that contains I16 data array.  When I put a probe on the wire, the probe shows the data as it should.  When I select a custom probe via 'custom probe,' 'controls,' 'waveform graph.', the waveform graph probe remains grayed and does not show the data.  Had no problem with this in v7.1.

Interesting...

I can confirm that it does not work for integer probes (tried I16, I32, U32). It  works if the data is set to DBL.

(Downconverted, all data types work fine in LabVIEW 8.0.)

My vote is that this is a bug, and a pretty annoying one.

Hi Don,

I hope you're doing well.  This was reported to R&D (# 40THMI99) for further investigation.  It looks like the waveform graph custom probe does not have the same behavior with the DBL data type.  A couple of work-arounds may be to create a subVI to behave as a probe instead, or you can add another waveform graph to your VIs front panel.  We definitely appreciate the feedback.  Have a great day!

Did this get fixed in LabVIEW 8.2.1 and if not, why?

Still not working in 8.2.1. Just tried it.
