Cannot evaluate expression on Banner page

[Jedidiah]

Same thing couldn't get JDF #2 to work.

[JavierM-Xerox]

Send me the workflow and the exact JDF you are using (Once something launches I am generally done with it so it would help to get the released JDF).

[Jedidiah]

Sent you a message

[JavierM-Xerox]

Thanks - I just tried it and sure enough it seems there's a bug with that variable (although other variables seems to be working ok).

Two things: Please submit to the hotline.

Also - as a workaround, Create the JDF with the stock name in both the ProductID and the DescriptiveName attributes.

Use the $FFwfJob.mediaDescription$ variable to add the stock name to the banner page.

[Jedidiah]

Alright I'd try this. Does a similar workaround exist for $FFwfDoc.color$? You can test with  JDF 3 or JDF 5 and should see the same issue.

JDF 3 for reference:

Color is working ok for me using the following text:

Name: $FFwfJob.mediaDescription$
Width: $FFwfJob.mediaWidth$
Height: $FFwfJob.mediaHeight$
Weight: $FFwfJob.mediaWeightMetric$
Thickness: $FFwfJob.mediaThickness$
Color: $FFwfJob.mediaColor$

[Jedidiah]

That would be why... Colour is shown as $FFwfDoc.color$ in the Xerox_Freeflow_Core_4_0_Help.pdf and not $FFwfJob.mediaColor$ as you have it. Thanks I'd try this instead

[JavierM-Xerox]

That explains it, $FFwfDoc.color$ is for the printing color mode (aka CMYK vs K Only printing). It is not related to the media.

[Jedidiah]

Thank you. Is there somewhere where the media variables are listed?

I'm able to get colour and media info now, I also found that I can't retrieve the variable values if the media elements are referenced in a nested LPP or DPP element like uStore does

E.G.
<LayoutPreparationParams ID="LPP1" PartIDKeys="RunIndex" Status="Available" Class="Parameter" Sides="TwoSidedFlipY">
<LayoutPreparationParams ID="LPP4942" RunIndex="0~6 " Sides="OneSideFront">
<MediaRef rRef="M4942" />
</LayoutPreparationParams>
</LayoutPreparationParams>

It has to be added as a direct child of the main LPP element I.E.
<LayoutPreparationParams ID="LPP1" PartIDKeys="RunIndex" Status="Available" Class="Parameter" Sides="TwoSidedFlipY">
...
...
<MediaRef rRef="M4942" />
</LayoutPreparationParams>

Also via uStore multiple stocks could be provided per job, is there a way to list all of these? Currently only the last one referenced would be displayed.

[JavierM-Xerox]

One last thing - it seems this varaible was changed to $FFwfJob.mainStockName$

I missed that when I updated the documentation... (taking a note for the SP3 documentation)
