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#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.
