I’m trying to build report generation into my workflow.
I have a series of RDKit molecule images I want to print in an array.
When viewing in the “Table View” node and the component report view, the data is intact.
Once run through the “Report PDF Writer” node, some of the cells are blank where there should be a molecular structure.
I see a similar issue was reported for KNIME 5.3, and was wondering if any workaround has since been found for KNIME 5.4.4
Thank you for taking a look! I have reproduced the issue with a public dataset, and a subset of my workflow. It looks like my procedure is much the same as your workflow, however it seems this only becomes a problem after the forth page of the PDF, which your test set has been to small to see the issue.
The first 4 page render as expected (regardless of the number of molecules) and then renders blank cells afterwards.
I have uploaded the workflow, input data, and slightly varying output reports which highlight the issue. Do let me know if the issue is reproducible for you with this workflow. I also run this workflow on KAP 5.4.4 on Windows 11.
Thank you for the detailed information.
I was able to reproduce the issue in my environment.
I believe it’s a bug.
The location of the missing structure display changes with the Table View’s row height.
It appears that this problem does not occur when using Report HTML Writer.
The best approach might be to convert it to HTML and then PDF it using a web browser, even if it adds a step.
