Usage considerations

Offline mobile

While the process task link component is partially compatible with offline mobile, using the component to link to tasks assigned to groups and social tasks is not supported for offline mobile. However, if a user accepts a group-assigned task while online, they will be able to access it offline.

Retrieving task IDs

To retrieve task IDs, use the Execute Process Report Smart Service and pull from the column that returns the list of IDs.

Using process tasks links with other components

To display a single link or array of links, use the process task link inside of the link field component.
To display a link in a grid, use the process task link inside of a grid text column.
To add a link to an image, use the process task link inside of a document image or web image.
To add a link to a chart series, use the process task link inside of the chart series component.

Examples

To experiment with examples, copy and paste the expression into an interface object.
