Thoughts and Learnings

Data transforms have 4 fields- Action, Target, Relation and Source which can be used as per the scenario. Data transforms can be used for the following: Set values for properties Update a page Remove a page Apply another data transform To check for conditions ( When, otherwise when and when) Looping through pages The usage is not limited to these. They can be used for adding comments and sorting though I have not worked on them. If you are trying to use an activity only for the above mentioned scenarios, it is best to use data transforms instead.

Things to do if you want to show a screen The first thing we need for showing a screen is a layout. Layout comes inside a section Section comes inside a harness Harness is shown through flow action Flow action is configured only from an assignment shape An assignment shape requires a flow A flow requires a start and end shape. Hence, to show a screen, start from a flow and proceed backwards from this list.
