RegEx Filter Inaccuracy - Columns to process selected but still not processed

Feedback & Ideas
1

Hi,

this has been reported before but I cannot find the ticket. If a RegEx does match and is accurate enough but there is another column containing the string like “h1”, it causes the matches column to still be excluded.

Visually Knime tells the user everything is all right but it isn’t.

Bad
RegEx: WebDriver: Current URL|Domain|Request Path|Containers|h1|Row Index

Container H1 Column not processed

When enabling case sensitivity the filtered columns do not change but the result is as expected.

Correct
RegEx: ^(WebDriver: Current URL|Domain|Request Path|Containers|h1|Row Index)$
image

Container H1 Column properly processed

Thank you @mwiegand for reporting this.
Would you share a simple and minimal example workflow which reproduces the issue?

Hi @mwiegand,

Would you check and see if this is still an issue in the latest AP version? (5.4.0)
