Table Editor Input Validation

[d3n1s]

Hi Knimers,

is there a way to perform an input validation in the Table Editor at the moment of the user input:

I understand that the validation can be done afterwards, but in my case adding a few extra nodes after the Table Editor would slow down the component (not desired by the application users ).

Could we attach some JS in the Table Editor in the same way we do with CSS?

Any recommendations are welcomed.

Thanks & regards,
Denis

Hi Denis,
I’m afraid at the moment the verification can only happen in the workflow after the table editor. I suggest wrapping the component it is in in a recursive loop that shows the same component as long as there are errors. In the first iteration, you just pass an empty “error” column into the loop and when the validation yields an error, you pass that from the recursive loop end back to the loop start (now the “error” column not empty). The error you can then show in a Text Output Widget (maybe with some HTML and CSS making it red). I know it is not what you have asked for, but probably the next best solution to your problem
Kind regards,
Alexander

Hi Alexander,

that’s actually a good idea. I will give it a try.

Thanks a lot,
Denis
