Extending Case Management: how to implement validation in Create Case form?
The create button to actually create the case is not extendible, so the only other option is field validation. In this case, we need validation on a select-single, which does not support async-validators property. So the final option is to use custom-messages property. We are doing the validation in JS (because we cannot pass virtual fields to action chain..), so my question is how to update the custom-messages from JS, or is there a better way I missed?
