BIRT Report issues on Webportal

Hi,

I’ve created a workflow that works fine in the Analytics Platform and the associated report also looks fin on the BIRT Report Viewer. However the Report does not show on the WebPortal, returning an error.

When checking the 'ViewReport->In Web Viewer the following error is shown (See below):

Does anyone have an idea of what’s going wrong?

Thanks in advance!
Mike

Hi, Is it possible to share via DM or email to support, a minimal workflow that reproduces the issue?

Hi Jon,

Thanks for your reply. Wasted ages trying to fix this but still no joy. By addressing the 'Element ID’s which were returning errors in BIRT I managed to generate a workflow that returns no errors (I think the errors were referring to cases when missing values were returned to the dynamic data in the BIRT report).

However. Eeven though no error is being returned in BIRT and all looks well it still fails to execute in the WebPortal. When I save the executed job again I can find no issue… I’m not sure how I could share a minimal workflow with you that still has the same issues (The full workflow extracts DB from our DBs which I wouldn’t be able to share). Any ideas…?
Thanks again for any help!

I’d probably try to add a row filter after the DB extract that focuses just on the problematic rows. Then if possible I’d use the Table Creator to create a table that causes the same issue, but is filled with dummy data.

Hi Jon,

After much trial and error I’ve got something that seems to work now based on the following points:

• The report returns dynamic text which is sometimes missing data – BIRT doesn’t seem to like this so I’ve changed missing data to a text stating ‘Missing data’ before sending it to BIRT
• Since I created the workflow by copying and modifying a previous (successful) workflow, BIRT seems to remember the old data binding for each table despite the fact that I deleted the old data binding and reassigned it to new data. At the end I deleted the old report completely and started from scratch
• Similar to the missing data issue in BIRT, I send an image using the Image to Report KNIME node. Sometimes this image is blank due to missing underlying data, this seems to work OK in BIRT with blank images from the ‘GroupBy Bar Charts (JFreeChart)’ node but not for images from the ‘Line Chart (JFreeChart)’ node. So I converted the latter line chart to a bar chart…

After making all these changes the workflow seems to work OK on the Webportal at the moment…

Thanks for all your help.

Cheers,

Mike
