Charts are randomly blank in Nprinting May 2023

[cedric_loch]

Dear Qlik Support Team,

After upgrading to the last version of Qlikview and Nprinting (May 2023), we noticed that charts set to be displayed as images in Excel reports are randomly blank.

See screenshots below: same report template with different renders.

In the Designer, images appear correctly in preview mode.

What we tried so far with no success : open/save the report and update the metadata

Any idea what happens ?

Regards,

Cédric.

Hello ,

1. Please review the following article link below for unsupported items.
2. If none of those items work to resolve the issue open a support case and provide a full set of Nprinting logs, a copy of the Nprinting report and QlikView qvw used to create it.

@cedric_loch there are many potential causes of images randomly missing...

as a test if you re-create your report template is the issue still there?

Hello Ray,

Thanks for the quick reply. 

We have dozens of templates and every one was correctly generated before the update.

We come from NPrinting 22.15.11 May 2022 SR3 and considered upgrading to May 2022 SR4 until we saw the May 2023 versionn which we finally installed.

I definetly will follow your link and read it carrefully.

Hi David,

We plan to test with a complete from-scratch new template, but I don't consider this as a real solution...

As advised I ran 2 tests:

#1: from an existing template, I deleted the charts from the sheet, saved, reopened and added them again -> charts are correctly displayed in the previewed reports, but images are still randomly blank when the publication task is executed.

# 2: I created a new template, defined a dimension as cycle, added charts as images -> the images are correctly displayed in the previewed and the final reports, in other words it works fine.

My guess is that all my reports have been somehow corrupted when we made the upgrade...

Have any other Nprinting users encountered such behaviour ?

Cédric.

Hi @cedric_loch 

I dont think your reports got corrupted. I think it is a case of QlikView vs NPrinting compatibility and it seems like there is only 1 combination of 2023 May QlikView and NPrinting which is supported at the moment so not much we can test or do. 

I would say - open support ticket ASAP and let Qlikkies have a look at it. @Ruggero_Piccoli - what is your opinion? 

Thanks

Hi @Lech_Miszkiewicz 

Thanks for your message, ticket is on his way to Qlik.

In the meantime, I will try a last shot by creating a new report based on an existing template.

I keep you posted.

Regards,

Cédric.

Hi,

Are you connecting to QlikView or Qlik Sense? Which version?

Do you have filters applied on the report with the issue? With the same filters, do you randomly have black charts? I mean if you run the same task multiple times do you always have the same result?

Try also to apply the same filters in the source app and export the same objects that are blank without using Qlik NPrinting and check the result.

Best Regards,

Ruggero

Hi @Ruggero_Piccoli ,

based on description of the post it is QlikView latest version with latest NPrinting - that should be QV May 2023 an NP May 2023 - @cedric_loch  - can you confirm that?
