This page provides an overview of configuration concepts. Refer to the Reference section for complete property documentation.

​
What is the difference between widget parameters and administration properties?

Nextedy GANTT uses two levels of configuration. Widget parameters are set per-widget instance on the Polarion page and control the behavior of that specific Gantt chart. Administration properties are set globally in the Polarion administration panel and apply to all Gantt widgets across the project or server. Widget parameters take precedence over administration properties when both define the same setting.

How do I set up field mappings for the Gantt chart?

Field mappings tell the Gantt which Polarion work item fields to use for task start dates, end dates, duration, and progress. You need at least two of the three date fields configured: startField + endField, startField + durationField, or endField + durationField. The Gantt validates these mappings at render time and displays an error message if the combination is invalid.
You must configure at least two of startField, endField, and durationField. The Gantt widget will not render without a valid field mapping combination.
Set the dependsRoles widget parameter to specify which Polarion link role IDs represent finish-to-start dependencies between tasks. Work items connected with these link roles appear as dependency arrows in the Gantt chart. Similarly, use parentRoles to define which link roles represent parent-child hierarchical relationships displayed in the Gantt tree structure.

​
How do I configure the Gantt to show a specific work item type?

Use the mainDataType widget parameter to specify the primary Polarion work item type that the Gantt chart displays. For example, set it to task, workpackage, or feature depending on which work item type your project uses for scheduled items.
The exact work item type IDs available depend on your Polarion project configuration. Check your project’s work item type definitions.

​
Can I make the Gantt chart read-only?

Yes, set the readonly widget parameter to true to disable all editing capabilities. This hides the Edit button and prevents drag, resize, and add-task operations. Conversely, set alwaysedit to true if you want the Gantt to always be in edit mode without requiring users to click an Edit button first.

​
How do I configure the resource field for task assignment?

The resourceField widget parameter specifies which Polarion work item field is used as the assigned resource. This drives both the resource view display and the resource filter functionality. The field can be set to the assignee field, a category field, or a custom field depending on your resource management model. For full setup instructions, see Set Up a Basic Gantt Chart and the Reference documentation.
