Bug report: Integer Input node (legacy, deprecated) works in 4.5, not in 4.6

[Aswin]

Dear Knimers,

I have a workflow that loads and runs without problems in 4.5…

…but not in 4.6:

Knime then offers to install the missing nodes:

But, strangely, it offers to install the R scripting package, which has nothing to do with the Integer Input node. Moreover, this package is already installed:

Console output:

ERROR LoadWorkflowRunnable Errors during load: Status: Error: tmpflow3 3 loaded with errors
ERROR LoadWorkflowRunnable Status: Error: tmpflow3 3
ERROR LoadWorkflowRunnable Status: Error: Node “Integer Input (legacy) (deprecated)” not available from extension “KNIME Interactive R Statistics Integration” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.quickform.nodes.legacy” is not installed)

Attached are the workflow (exported from Knime 4.5) and the log when trying to load the workflow in 4.6 and following the prompts for installing missing extensions.

There was a bug in KNIME 4.5 where the R extension illegally claimed ownership of those legacy quickform nodes. This issue is fixed in 4.6 but “old” workflows (created < 4.6) will still have that association.

To fix it just install the KNIME Quick Forms (legacy) extension from the KNIME Labs category.
