Modifying the HTML Client Object Selection Page
To enable recognition of custom parts as a sub-class of WTPart and not just the supported type in the Creo Parametric HTML client object selection page’s default implementation, you must add support for the custom part in the configured wt.query.SearchAttributeListDelegate. (For more information see Customizing the HTML Client Object Selection Page .)
In addition you must modify the Creo Parametric HTML files that use the object selection page, and use the xconfmanager modify or override the type list ID entries in com\ptc\windchill\cadx\propfiles\picker.properties.

For wt.query.SearchAttributeList, which is the default configured search attribute list, the type ID is referred to as the query value. (For more information, see Customizing the HTML Client Object Selection Page ).
