can anybody help me to correctly catch errors when loading internal data?
So far, I took care about the internal data by 'loadInternals' and 'saveInternal' in the node model. But how would it look like if the loading of internal data fails (due to corrupted files e.g.)?
I tried to throw a 'CanceledExecutionException' in 'loadInternals', which throws an error, but the node is still executed after loading the workflow.
Instead, I would like the node to be reset; but looking into the code KNIME-nodes like 'Linear Correlation' did not help as it does not use the 'loadInternals' (I did not get the mechanism this node uses to load its internal data).
What would I have to do to get the node reset to 'CONFIGURED'?
