import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.jira.groovy.user.FieldBehaviours
import groovy.transform.BaseScript

@BaseScript FieldBehaviours fieldBehaviours

def clientName = getFieldById(getFieldChanged())
def maidID = getFieldByName("MAID Multi")
def clientNameVal = clientName.getValue().toString()

// Getting select field optionsdef selectCustomField = customFieldManager.customFieldObjects.findByName("MAID Multi")
def selectConfig = selectCustomField.getRelevantConfig(issueContext)
def selectOptions = ComponentAccessor.optionsManager.getOptions(selectConfig)

if(clientNameVal == "[aarkishpharma]"){
    maidID.setFormValue(selectOptions.findAll{it.value in ['900702']}*.optionId)
}else if(clientNameVal == "[acellapharma]"){
    maidID.setFormValue(selectOptions.findAll{it.value in ['900025']}*.optionId)
}else if(clientNameVal == "[aarkishpharma, acellapharma]"){
    maidID.setFormValue(selectOptions.findAll{it.value in ['900702','900025']}*.optionId)
}
