Hi

I have a text field in the configuration section of my plugin. The expected values are numbers separated by ‘,’ eg 1,5,10.&nbsp;User should not be able to set this value to 0. How I can validate the field?

AFAIK its not possible due to bugs in extjs version used by shopware.

unless you can write your rule with something else than regular expression.
