RE: poly item add column

yes properties need to be existing on each polysource. here is a sample method I have used when working with polyitems. It allows you to automaticaly push a new property from the polyitem to the polysource (also I realize I'm looping on an apply(), this could be enhanced)

// Get innovator ref
Innovator inn = this.getInnovator();

// retrieve the Poly-itemtype
Item polyItemType = inn.getItemById("ItemType", this.getProperty("source_id"));

// retrieve the added property name
String newPropertyName = this.getProperty("name");

// test if the itemtype is a polyitemtype
if (polyItemType.getProperty("implementation_type") == "polymorphic"){
    
    // get polysources
    polyItemType.fetchRelationships("Morphae");
    Item Morphaes = polyItemType.getRelationships("Morphae");
    
    // for each source - check if the property exists 
    for (int i = 0; i < Morphaes.getItemCount(); i++)
    {
        // get the morphae
        Item Morphae = Morphaes.getItemByIndex(i).getRelatedItem();
        Morphae.fetchRelationships("Property");
        
        // test if it has the added property (check just by name)
        if (Morphae.getRelationships("Property").getItemsByXPath("//Item[name='"+newPropertyName+"']").getItemCount() < 1){
            
            // Clone the property
            Item distributedProperty = this.clone(false);
            
            // Add the Property
            distributedProperty.setProperty("source_id",Morphae.getID());
            
            // Perform the query.
            Item results = distributedProperty.apply();
        }
        
    }

}

return this;
