Found it.. It appears to be called "Service"... It's just missing from the docs in 2.2b2.

That means I can't do my generic InputStreamLink type thing.. But a File specific one is probably better anyway. What is stumping me is that the documentation doesn't show a parameter in the ServiceLink that specifies the name of the Service.. is this an error in the documentation?

The service will download that data in a seperate request cycle. For example, the Chart service encodes the identify of a component that can provide the chart data. Assuming your data comes from a database, your token should include the primary key, perhaps the table, perhaps some extra authentication data. -- [EMAIL PROTECTED] http://tapestry.sf.net > Thanks for the suggestion. > Based on your suggestion, I decided to implement a generic > component/service/asset combination that I could use for handling any of > these "click to download" situations by providing an inputstream to a > "DataStreamLink" component.
