Set options on select list based on chosen options

[aviv_eldad]

Hi,

I have a hierarchy on my project of Stage -> Team assignment, and when you create a team assignment you choose a team allocation (team and sub-team).

I wrote a script runner behavior. when I create a new "team assignment" issue on my project, the script takes all the values of team assignment allocation that have already been created under the stage.

What I want is that in the create screen, on the team allocation field, it will show only the options that were not selected. I managed to create a list of all the option that has been selected, but I don't know how to extract the values, and how to set the "new" option.

Now the list looks like this: [[null: value,1 :value], [null:value,1 :value], [null:value,1 :value]].

and here is the code:

import com.onresolve.jira.groovy.user.FormField
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.ModifiedValue





def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def issueManager = ComponentAccessor.getIssueManager()
def optionsManager = ComponentAccessor.getOptionsManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()

if (getActionName() in ["Create Issue", "Create"]) {
FormField parentKey = getFieldById("customfield_11200")//parent key field
def val = parentKey.getValue()
    MutableIssue parent = issueManager.getIssueObject(parentKey.getValue())
    def childern = []
    def childLinkId=10400
    issueLinkManager.getInwardLinks(parent.id)
        .each { link->          
    if(link.linkTypeId == childLinkId){
            childern.add(link.getSourceObject())
    }
    }
   
     def ta = []
    CustomField teamAssign = customFieldManager.getCustomFieldObject("customfield_10905")//team assign field
    childern.each{child ->
         MutableIssue childNew = child as MutableIssue;
        ta.add(childNew.getCustomFieldValue(teamAssign))

    }
    ta.unique()
log.warn("team assign: " + ta)



}

Thank you for your help!
