Using a data version gadget
Data version gadgets display available versions of BIRT data object store files for a user to view. The developer adds a data version gadget to a dashboard and selects a data object store file. All available versions of that data store file are displayed in the data version gadget. The developer then displays data from the same data object store file in data visualization gadgets, such as a chart and a table, on the dashboard. When the user selects a version of the data store, those gadgets update to display data from the selected version.
Selecting a data object
The data version gadget displays the version number and, if available, the version name of the each version of the selected BIRT data store file. For example, if the dashboard developer wants to display the Sales.data file in a data version gadget, all versions of the Sales.data file are displayed in the data version gadget.
Choosing a selector type
You can display data version gadgets in a combo box, list, or radio types. Use the Data Selector Gadget Wizard—Type options to change how the data version gadget is displayed, as shown in
