Specifying Datautility for Columns
Data utilities allow developers to post-process and/or augment the data returned by the low-level data acquisition API. The additional information can be returned by an additional query, a call to a service, or whatever else you can get at via Java code. To specify the data utility for a column can be done by using setDataUtilityId() in table config.
ComponentConfigFactory factory = getComponentConfigFactory();
TableConfig table = factory.newTableConfig();
ColumnConfig col = factory.newColumnConfig("iconType", true);
col.setDataUtilityId("typePicker.iconType");
table.addComponent(col);
To register the dataUtility, you need to put in *service.properties. An example entry is:
<Service name="com.ptc.core.components.descriptor.DataUtility">
<Option serviceClass="com.ptc.windchill.enterprise.picker.type.
dataUtilities.IconTypeDataUtility"
requestor="java.lang.Object"
selector="typePicker.iconType"
cardinality="duplicate"/>
</Service>
