Hiding a Database custom field based on sub-task issue type

[jmodi1982]

Hi,

I am trying to hide a database custom field based on sub-task issue type using behavior plugin but it is not working. I have tried below script in behaviours plugin - 

public void setPriorityJustification() {

    FormField priField = getFieldById ("issuetype")

    FormField priJustField = getFieldByName ("CustomField_1234")

    String priority = (String) priField.getFormValue()

    if (priority == "10007") { // 10007 is 1 of the issue type

        priJustField.setHidden(false)

    }

    else {

        priJustField.setHidden(true)

    }

}
