Input Dialog Mass Processing

Modeled input dialogs can be used to create a multi-selection for mass processing actions. See Mass Processing Overview for more information. This requires the following setup:

• A file input parameter must be modeled.
  • The referenced file descriptor must be structured (table).
  • The UI Multi Selection attribute must be set to “true".
  • Only one structured file input parameter is allowed per input dialog.
• The tool descriptor must be referenced by an action descriptor with the attribute Mass Processing set to “true".

If executed, the dialog displays the referenced file as a table with checkboxes in the first column. See figure below:

The dialog behaves as follows:

• Depending on the UI Mandatory attribute, the dialog can only be confirmed if at least one line (checkbox) has been selected.
• On confirmation, the dialog overwrites the current multi-selection (mass processing context).
• All properties of the selected line(s) are stored in the “previous tool” property pool of the mass processing contexts.
  • Subsequent tools can read those values using input parameters of the type Mass Processing and the parameter from “Previous Tool”, referencing the desired property.

Rows in a dialog can be pre-selected by adding a Table Row Selection condition.

It is possible to define more than one Table Row Selection for an Open Modeled Dialog tool:

• Each Table Row Selection must refer to a file input parameter of the Open Modeled Dialog tool.

• Different Table Row Selections cannot refer to the same file input parameter from the Open Model Dialog tool.

• A Table Row Selection can contain either a complex or a simple condition:

  • A row is pre-selected when the condition is true.

  • If no condition is added to the Table Row Selection all rows are pre-selected.

• A complex condition can contain any number of complex or simple conditions.

• See Enabled/Visible Condition for more information on the evaluation of conditions.
