How to validate if a zip file is attached in the transition

[Chow King Tak]

I am using Scriptrunner to validate if a zip file is attached in the transition and find the code from  https://scriptrunner.adaptavist.com/5.0.3/jira/recipes/workflow/validators/validate-attachments-links-in-transition.html#_validating_attachments_added_this_transition  and set the code in the transition validator.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.IssueFieldConstants
import com.atlassian.jira.issue.attachment.TemporaryWebAttachment
import com.atlassian.jira.issue.attachment.TemporaryWebAttachmentManager
import webwork.action.ActionContext

def temporaryAttachmentUtil = ComponentAccessor.getComponent(TemporaryWebAttachmentManager)
def formToken = ActionContext.getRequest()?.getParameter(IssueFieldConstants.FORM_TOKEN)

if (formToken) {
def tempWebAttachments = temporaryAttachmentUtil.getTemporaryWebAttachmentsByFormToken(formToken)
tempWebAttachments.each { TemporaryWebAttachment it ->
log.debug "Uploaded attachment name: ${it.filename}"
}
}

I upload the attachment in the transition form but it doesn't work in my JIRA 6.4.  It is checked that the "formToken" is null so it cannot flow in to "if" clause. Do I miss something or is there another way to do that?

Thanks in advanced.

Hi, Chow,

you can try reading transient parameters map that is passed into your main Validator#validate method. 

User data that is updated in the transition dialog is usually kept there.

HI, Mikhail Kopylov,

Thanks. Is there any codes or link I can reference since I am not familiar with script?

Thanks.

I'm not familiar enough with script runner, I usually write my own plugin in Java.
