This example describes how to create a form that lets users remove an asset from a project. The active project ID is passed to the form handler. The asset name appears next to a checkbox with the label: Discard this asset? When the checkbox is selected, the asset is saved to the form handler asset property. By setting assetAction to the value of the DISCARD_ASSET_ACTION property, you indicate that the specified asset is removed from the specified project. A button at the bottom of the form invokes the handlerDiscardAssets method.
