How to make attachment field mandatory based on cascading select?

Question

In our JSD customer portal, we want to make attachment field mandatory based on cascading select field option, which is (parent2,child3) in create transition

We tried using add-ons like JSU and JWT, but no luck.

or at least hide Attachments field in create transition when the cascading field option is not equal to (parent2,child3) and show attachments when options is equal to (parent2,child3).

Can anyone please share your knowledge or solution to achieve this?

Thanks

Hi @KRC

your use case can be achieved pretty quickly in JWT. I guess you didn't come across the usage example Make attachment mandatory depending on the value of certain custom field?

The only difference in the setup is that you will validate on a cascading select custom field. So using the Boolean validator with math, date-time or text-string terms, validate %{nnnnn.1} where nnnnn is the field code of your cascading select custom field and 1 will return the value "child3". This means:

%{nnnn.1} = "child3" IMPLIES {00135} > 0, where {00135} is a virtual field for "Number of transition attachments"

in other words, your validating: "select list is NOT "child3" OR the number of attachments is > 0". So one of the options will always be true and the attachments only count when they have to. :)

Best, Max

Figured it out, but anyways plz share your knowledge. We might get a new perspective

I used JMWE, add-on.

* In create transition>validators> Fields required Validator(JMWE add-on)
* In fileds-  Choose Attachments
* Error Message - Add whatever u want to display
* Checked conditional validation and I used:  issue.getAsString("CascadeSelectCustomFieldName") == "Parent2,Child3"

Will update if anything changes.

Peace...
