RE: Disabling field in relationship

Hi philn,

I faced the same challenge as you in the following scenario:

We have a custom item type Part Request with a relationship to a Manufacturer Part. Unless the Part Request is in the LC state 'Awaiting AML Approval' the field is_approved on the relationship cannot be edited.

I looked to the Programmer's Guide pp. 63-64 and found inspiration for the following:

This client method needs to be placed on the Property is_approved. Pro tip: This item type can only be locked when the parent item type (Part Request in my scenario) is locked first. Once the Property is locked, add a new client method with the Event OnEditStart with the following content:

var inn = this.Innovator();

var relationship = inn.newItem('PartRequest ManufacturerPart', 'get');
relationship.setProperty('id', relationshipID);
relationship = relationship.apply();

var prq = inn.newItem('Kam_PartRequest', 'get');
prq.setProperty('id', relationship.getProperty('source_id'));
prq = prq.apply();

var prqState = prq.getProperty('state');

if(prqState === 'Awaiting AML Approval') {
return;
}

var cellValue = gridApplet.GetCellValue(relationshipID, colNumber);
if(cellValue !== '') {
return false;
}

Hope this helps;

Small note:

The magic arguments relationshipID and colNumber along with gridApplet is given by the anonymous method containing your method code, like so

(function anonymous(relationshipID,relatedID,propertyName,colNumber,gridApplet
) {
debugger;
var inn = this.Innovator();

var relationship = inn.newItem('PartRequest ManufacturerPart', 'get');
