I was trying to add a row to a business object in add case page by using javascript and come across following code. 

collectionController.beginChangeSet();

/* Build the values for the business object members. */
/* Assume all members will contain data for all rows. */
/* In the view, output two rows like the following rows: */
/* 10, Baker Street, Costa Mesa, Oasis, California, USA*/
/* 20, Ebay Street, Costa Mesa, Lotus, California, USA */
var propValues = {};
propValues["PPA_ProjectOwnerType"]= ["Test 1","Test 2"];
propValues["PPA_ProjectOwnerName"]= ["Baker Street","Ebay Street"];

/* Get the property controller of the business object. For instance, SAT_Residence: */
var residenceController = collectionController.getPropertyController(solutionPrefix + "_ProjectOwnersBOProp");

/* Get the members of the business object: */
var children = residenceController.getAttribute("boChildren").get();

/* Set the individual value arrays to the child controllers: */
/* This helps in displaying the changes on Add Case: */
var num_values = propValues["PPA_ProjectOwnerType"].length;
for(var j=0;j < num_values; j++) {
var childController = collectionController.getPropertyController(children[j]);
var propname = solutionPrefix + "_" + childController.getAttribute("name").get();
var prpN = propname.replace(/\s+/g, '');
childController.set("value",propValues[prpN]);
}

/* Loop through the values and set them to the business object controller: */
var values = [];
for(var i=0;i < num_values; i++) {
var updateJson = {};
updateJson.id = null;
var props = [];
updateJson.properties = props;
for(var j=0;j < children.length; j++) {
var prop = {};
var childController = collectionController.getPropertyController(children[j]);
prop.name = solutionPrefix + "_" + childController.getAttribute("name").get();
prop.dataType = childController.type;
prop.cardinality = childController.cardinality;
var prpN = prop.name.replace(/\s+/g, '');
prop.value = propValues[prpN][i] ;
props.push(prop);
}
values.push(updateJson);
}

residenceController.set("value", values);

/* Complete a batch of changes. This tells all subscribed widgets to refresh. */
collectionController.endChangeSet();​

And my business object was created as 

This code is working when I called it inside beforeloadwidget event action. (without using ChangeSet())

But when I tried this inside button action, I am getting no response.

in both ways when I tried to click the add button, I am getting following error.

CaseMgmtException: FNRPA0087E An unexpected error occurred.

I am using BAW 20.0.0.1

I am looking a way to fix this. I just need to add a row to the business object with javascript in add case.

Many thanks in advance.
