Groovy expression to see if there are any subtasks?

[Cole]

I am trying to use the transition issue post function and want it to only occur if there are no subtasks for that issue. 

I have checked the box "Only if condition is true", but I am unsure what my expression would be to look for subtasks?

Basically I would want it to say something like:

If no subtask for current issue {

Return true

}

Try this?

def subTasksList = issue.getSubTaskObjects()

if (subTasksList.size() < 1) {
 return true
}

I see this error:

No signature of method: com.innovalog.jmwe.IssueProxy.getSubTaskObjects() is applicable for argument types: () values: []
groovy.lang.MissingMethodException: No signature of method: com.innovalog.jmwe.IssueProxy.getSubTaskObjects() is applicable for argument types: () values: []

Are you using Cloud or Server? The above script worked for me using JIRA Server 7.x with the following post function configuration.

I am using JIRA Server 7. Does there not need to be some kind of reference to a class at the top or something?

Try adding these two lines to the top of the script.

import com.atlassian.jira.component.ComponentAccessor
def issueManager = ComponentAccessor.getIssueManager()

Perhaps also 

import com.atlassian.jira.issue.Issue

I ended up using a built in script to fast-track a transition. For the condition I used "issue.getSubTaskObjects().size() < 1" and it worked.
