Hi,
I have a fragment from which I would like to read multiple sap.ui.layout.form values.
Since i had used .clone() functionality to add the rows dynamically, i would like to read all the form values at a single shot instead of accessing byId() for each row.
Any advice is deeply appreciated
Thanks,
Natarajan

Hi ,
incase of getting form field values, you shall loop the form and get cells and its values as below
var oFromFields = sap.ui.getCore().byId("formId")).getFormContainers()[0].getAggregation( "formElements");
loop the elements to get its values

You could use the json model to do this for you. As the form has the form containers aggregation binding and form container has form elements aggregation binding, you can bind the model to this and generate the new rows without cloning just by adding a new row in the json model data, which will automatically add the row to the aggregation. This is a better approach as getting the data byId is very unreliable.
1. Create a json model with initially one row
2. Use the factory functionality to generate the item template dynamically for your form items, as you are generating different controls dynamically for different rows.
3. When the add button is clicked, add another row to the json model, which will automatically trigger your factory function and you will pass the template back to the form.
Also you can do the same using the odata model, but you need to get the template and use the element binding and trigger submit changes at the end, but this will trigger the post call.
BR,
Mahesh
