Groovy script doesn't update insight attribute

[Lilia Sobchuk]

Hi,
we have a groovy script- postfunction which should get a value from a custom field (quantity) and subtract this value from available quantity (insight attribute) and add it to reserved quantity ( also insight attribute). But when I run it - nothing is updated, the test script result return "true". 
I've checked all the id present in the script - all are right.
Please help me to understand what is wrong with the script

Here is the script;

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.MutableIssue;
import org.apache.log4j.Logger;
import org.apache.log4j.Level;

def AddIntegerToInsightAttribute (Issue issue, int jiraFieldId, int insightFieldId, int attributeID, Boolean addInt = true) {

def log = Logger.getLogger("com.onresolve.jira.groovy");

/* Get Insight Object Attribute Facade from plugin accessor */
Class objectTypeAttributeFacadeClass = ComponentAccessor.getPluginAccessor().getClassLoader().findClass("com.riadalabs.jira.plugins.insight.channel.external.api.facade.ObjectTypeAttributeFacade");
def objectTypeAttributeFacade = ComponentAccessor.getOSGiComponentInstanceOfType(objectTypeAttributeFacadeClass);

/* This is the custom field with the value you want to add to an object attribute */
CustomField jiraCustomField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject(jiraFieldId); // Quantity Delivered (Integer) custom field

/* This is the custom field where the object/s you want to set the value */
CustomField insightCustomField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject(insightFieldId); // Stock Item (Insight Object single select) custom field
def insightObjects = issue.getCustomFieldValue(insightCustomField); // "issue" variable is always accessible in post function scripts.

/* This is the priority object type attribute and the one we want to modify */
def origValue = 0; // Default to an original value if attribute is empty

if (insightObjects != null) {
insightObjects.each{insightObject ->
/* Load the attribute bean for reserved quantity */
def objAttrBean = objectFacade.loadObjectAttributeBean(insightObject.getId(), attributeID)
if (objAttrBean == null) {
/* If no value, throw error */

return false;
} else {
/* If value was defined, store it */
origValue = objAttrBean.getObjectAttributeValueBeans().first().getIntegerValue();
}

/* Set the new values to the object attributes */
if (issue.getCustomFieldValue(jiraCustomField) == null ) {
log.info("InsightAttributeAndCustomFieldManipulation:AddIntegerToInsightAttribute - Integer parsing failed: custom field has no value - Issue: " + issue + ", jiraFieldId: " + jiraFieldId);
return false;
}
def jiraQuantity = issue.getCustomFieldValue(jiraCustomField).toInteger();

/* Clean the list of values */
def values = objAttrBean.getObjectAttributeValueBeans();
values.clear();

/* Create a new unsaved value */
def newObjAttrValBean = objAttrBean.createObjectAttributeValueBean();

if (addInt) {
newObjAttrValBean.setIntegerValue(origValue + jiraQuantity); // Set the Quantities in Insight Object
} else {
newObjAttrValBean.setIntegerValue(origValue - jiraQuantity); // Set the Quantities in Insight Object
}

/* Add the new value to the attribute */
values.add(newObjAttrValBean); // Add the value to the object attribute
objAttrBean.setObjectAttributeValueBeans(values);

/* Store the object attribute into Insight. */
try {
objAttrBean = objectFacade.storeObjectAttributeBean(objAttrBean);
} catch (Exception vie) {
log.error("InsightAttributeAndCustomFieldManipulation:AddIntegerToInsightAttribute - Insight object update failed: Could not update object attribute due to validation exception:" + vie.getMessage() + " - Issue: " + issue + ", jiraFieldId: " + jiraFieldId + ", insightFieldId: " + insightFieldId + ", insightAttributeName: "+ insightAttributeName + ", addInt = " + addInt);
}
}
}
