Error when printing worksheets

#1

Dear community,
when hitting the “print” button from a created worksheet that has 4 samples assigned, the following error occurs:

WS-001 - Unable to load the template ‘ar_by_column.pt’:

The file “ar_by_column.pt” resides in the folder

/home/senaite/buildout-cache/eggs/senaite.core-1.3.1-py2.7.egg/bika/lims/browser/worksheet/templates/print

Selecting “ar_by_row.pt” gives a similar error.

Is this the expected behaviour?
What can be done to cure this?

Thanks,
Andreas

Maybe wrong file permissions?
In my installation they look like this:

senaite :: ~ » ll /home/senaite/senaitelims/src/senaite.core/bika/lims/browser/worksheet/templates/print/
total 44K
drwxrwxr-x 2 senaite senaite 4.0K Mar 18 2019 .

I don’t know, what caused this issue.
A reinstall, however cured the problem and printing worksheets is possible now.

Thanks.

After entry of a measuring device, supplier, reference definition and reference sample (QC sample) the error is back again:

And as stated above: The template is obviously there.
So I don’t know why the server can’t find it.

Any clues anyone?

Thanks.

To nail it down a little bit more:
I can print a worksheet with samples/analyses assigned:

But as soon as I add a reference sample (QC sample), I get the error again:

It would have saved me some time, if someone told me that this was a known bug:
https://github.com/senaite/senaite.core/issues/1431

However, is there a Senaite Version, that does not suffer from this bug?

Thanks.
