PDA Scale Filipped Attribute Error

[rberger]

I'm using the VControl slider in the LV8 PocketPC PDA module.  I want to use the scale.flipped attribute node.  However, when I try building the app, I get an error stating kScale_Flipped is missing a VI or C file.  Whats going on?  Attached is the VI.

Is this property supported in 8.0 PDA?

I haven't had a chance to see 8.0 PDA yet, so I don't know how it works with unsupported properties - does it break your VI? Does it alert you at build time? Does it simply remove the unsupported ones from the selection list?

Is flipping the scale the only thing you are doing in your example?

Unsupported attribute (property) nodes break the VI.  This Flipped attribute does not break anything.  This just gives me that error when compiling

And is this the only thing in the example? I have seen cases in the past where seemingly unrelated code caused such errors. If it is the only thing, then this is probably a bug, at least in the sense that the node should break the VI. You will need someone else with 8.0 to check that. Are other scale properties supported?

BTW, they haven't been "attribute" node for several versions already.

You are right.  I get teh same error.  I even chopped out everything but the slider and the property node and get the same error.  I would say it is a bug that it does not break the run arrow or that it does not work.  I would expect it to break the run arrow on the next version of the PDA module, especially if it is a bug-fix release.

Hope that this helps,

Thank you all for helping with this.  I have reported this issue to R&D to investigate (CAR #3U6F043A).  I suspect that this is just one of the properties that is not supported on the PDA, so you might want to consider an alternative.  If you had any questions on this please let us know!

Thanks for posting, and have a great day!

To add more fuel to the fire, say you compile the attached VI in message 1 with out the scale flipped property node (formaly attribute node ).  Make sure the vertical slider has an INVERTED scale and a fill option of FILL TO MINIMUM.  While running the VI, press  the OK button to fire off the property nodes.  The vertical scale fill option reverts to FILL TO MAXIMUM at run-time!!!!  This is another bug!  Hopefully a patch will come out soon.

This was reported to R&D (# 3U6FO43A), but was determined to be expected behavior because the only slider scale properties that are supported on the PDA are scale.visible, scale.range.maximum, scale.range.minimum and scale.range.increment.

As for the documentation on this property...  This was reported to R&D (# 3WDICL00).

Thanks for the feedback!

For the documentation "bug"...

This was reported to R&D (# 3WDICL00) and was fixed in LabVIEW 8.2 PDA. Here is a link to the current evaluation software download for LabVIEW.

Thanks!
