Issue with regular expression in String widget

KNIME Server
1

Hi,

I’m trying to use a regular expression in a string widget to control user’s input. It works in Knime analytics - I get the error message ‘Input does not match the expected pattern’ when I enter an invalid value, but when I publish the workflow on the web portal, this check does not work anymore. The workflow hangs up when I enter an invalid value.

My regular expression is ([0-9])(.)([05])? to enter value like x.y where y is either 0 or 5.

Could you help? Would you have a working example?

Thanks,
Regards,
Claire

Hi Claire,

it works for me.
What version of KNIME and KNIME Server do you currently use?

Best,
Julian
