var addressTxt = new sap.uimons.Label({
                id : 'addressTxt',
                text : {
                    parts : [
                             {path : 'Street'},
                             {path : 'PostalCode'},
                             ],
                    formatter : function(Street,PostalCode){
                        var text = "";
                        if(Street)  text = Street+ ",";
                        if(PostalCode) text += PostalCode +","

                        return text;
                    }        
                }
                        });

I am using the the formatter function to concatenate two elements in to a text field here, how ever the values for the parameters are always null. What am I doing wrong?

• 1 The coding looks OK. Can you also share, how you set the model and the model structure? – cevou Commented Nov 13, 2013 at 15:05
• 1 the binding was indeed wrong! changed it to {path : '/details/Street'} and it works! My bad, Thanks a lot! – Themasterhimself Commented Nov 14, 2013 at 12:35
• 1 Btw: variable names should be lower case in JS. – cschuff Commented Jan 23, 2014 at 22:20

Here you go: http://jsbin./openui5-HTML-templates/82/edit?html,output

Think your main mistake was the parts array that is build without additional objects and 'path'. It directly takes the paths. Furthermore as long as the path is absolute inside of your model it needs to start with '/':

text : { 
    parts : [ '/street', '/postalCode' ],
    formatter : function(street, postalCode) {
        var text = "";
        if (street) text = street +",";
        if (postalCode) text += postalCode;
        return text;
    }
}
