Set Single Select Value to "Story" Scripted Behavior - Script Runner

[Jason_Galea]

Hi,

During a transition screen, i would like to set a field called "BRP Action Type" to "Story" and set as 'Read Only"' when another custom value called "Project Category" has "Agile selected"

For some reason, I do get the field set as 'Read Only' but the value is not changing to "Story"

Here is the script below:

import com.atlassian.jira.component.ComponentAccessor

def ProjectCategory = getFieldById(getFieldChanged())
def Selection = ProjectCategory.getValue()
def TechnicalContributor = getFieldById("customfield_13408")
def brpactiontype = getFieldById("customfield_13740")

TechnicalContributor.setHidden(true)


if (Selection == "AGILE") {
TechnicalContributor.setHidden(false)
TechnicalContributor.setRequired(true)

brpactiontype.setFormValue("Story")
brpactiontype.setReadOnly(true)
}

Any suggestions?
