I will focus in different new parts. See what they do and how I think they are now and how I imagine they can be in the future. . If you’re looking for more in depth information; Karol already wrote an impressive amount of information that you can find here : Design Studio 1.5: What’s New in? A (technical) View
The first and second blog you can find :
This blog on 1.5 new features is about data binding. It deserves a lot of attention, more than it is currently given I think, as it is a game changer in how you can manipulate components. This is the third part in a blog series about new features in DS version 1.5.
On Data binding
A lot of properties of basic components have now the ability to use a data binding function to set the value of the property. This property potentially saves a lot of scripting as a lot of properties can be automatically updated when the bound data source changes. You will find the data binding option by pressing the yellow left- and right arrow icon on top of the properties pane after you’ve selected a property.

Additionally you can do an output bind with list items where the choice of one of the members automatically triggers an action. Currently that is a filter action on a datasource.

The fun part is however that it seems that all the components can get bound this way. This opens room for a lot of master data driven options. For example. Create a datasource with in rows, component names and 2 key figures: left margin and top margin:
The data binding looks like this :
The value that you get can get passed along to a formatter. You can review the formatter in your Central functions in the outline view.
- The one thing what would be really nice here is that I would be able to pass the name of the component to the data binding JSON. Then I can just copy the component with data binding and the binding function would refer to the new component name J
(By the way : I do not say you should go this far with master data driven: It is an example in how far you can go).

What could be better?
What I notice is that once the data is populated the items aren’t refreshed if you filter the underlying Data Source. For the future I would like an option to make the binding either dynamic (update at each data source change) or static (stays the same). Now if I want something cascading I still have to fall back to scripting and as this is a common feature a lot of scripting has to be kept around, even after this feature is introduced.
Data binding will decrease scripting… a lot. Already this what we have can save us a lot of scripting. When the binding options get expanded even more you will be able to create large applications that can be managed for a large part by data sources.
The more I looked at it the more I thought that this could be actually the biggest feature for designers. Especially as I noticed in the SAP Insider Q&A today that a lot of people want to avoid scripting.
