Error in Molecule String Input

KNIME Analytics Platform
1

When using the new Molecule String input node I get following error message:

ERROR Molecule String Input 2:54       Retrieving SVG from view failed: Error executing JavaScript: Can't find variable: org_knime_js_base_node_quickform_input_molecule

The node else works except the image output which also shows above error message.

How can I solve this issue?

Hi,

can you attach a sample workflow, where this problem occurs for you. I will have a look at it then.

Hi 

With the latest KNIME 3.4, I still get the error: org_knime_js_base_node_quickform_input_molecule

Attached is the workflow.  I saw the same exception in either KNIME client or KNIME server.

Hope you can help me to resolve this - my team wants to enable molecule drawing at the webportal and executing the workflow once done drawing.

 

Thanks a million!
