New Functionality and Changes Introduced with FICO Xpress Insight Help 4.8

This section describes the new features and changes introduced with FICO^® Xpress Insight DMP Component Help 4.8

Summary

FICO® Optimization Modeler. has been renamed to FICO® Xpress Insight Web Client.
VDL and the JavaScript API have moved up to version 4.0.
The server encryption key is now located in a file named .xpress-insight-key. If you are upgrading from a previous version your encryption key will be moved to a file with the new name.

VDL 4.0

<vdl-chart> has been added, allowing an alternative means to insert simple charts in VDL views.
Added support for arrays with repeated index sets to be used in a <vdl-table>, by adding optional set-position attribute (to disambiguate occurrences of the same index set) to <vdl-table-column> and <vdl-index-filter> elements.
The <vdl-table> row-filter attribute has changed. The scope variables position and tableData are no longer passed in to the expression or callback.
Table columns can be hidden using the vdl-visible attribute, which must be an expression. This method of hiding columns should be used in place of any CSS styles or classes applied to columns.

JavaScript API 4.0

Upgraded to jQuery 3.1.1 which has removed previously deprecated APIs.
Removed the Chart component and the RGraph library. These have been replaced with vdl-chart.
Added support for AutoTables to use arrays that have repeated index sets. The following properties can now be an array (a non-array value is still valid, as before, and is treated as a singleton array):
- AutoTable~Config#indicesOptions
- AutoTable~Config#columnOptions#filter
- ScenarioObserver~BindAutoTableOptions#columnOptions#filter
- ScenarioObserver~BindAutoTableOptions#indicesOptions
Added onError callback to ScenarioObserver~BindAutoTableOptions, which will be called in event of invalid AutoTable configuration.
AutoTable#EditorValidateCallback arguments have changed. The cell element is no longer passed in. The new call signature is: new cell value, row data and row key (value, row, key).
AutoTable#editorOptionsSet and AutoTable#editorOptions are no longer used to render cells.
The AutoTable~RowFilterCallback signature has changed. The rowNumber and tableData arguments have been removed.
AutoTable and Table columns can be hidden with a new visible property.
