So you might come across some situation in which you want to repeat some part of your layout for each data item, but the number of items is unknown.
Fortunately for us, Adobe provided a component with Flex which we can use to achieve just what we want: repeating parts of the layout for every item in the data collection.
Let’s say we want to have an update page for our products in de database. On the update page we want to have 2 TextInput fields for each product: 1 for the name and one for the quantity in stock. Using the Repeater component I managed to do this in the following example (right click > view source) to see the sourcecode. The save button doesn’t do anything by the way, just decoration.
As you can see, i’m using the XMLList as the dataprovider for my Repeater. Inside the Repeater component, we can then use {repeaterID}.currentItem to get the attribute values for each of the products.
