Hello,

I have a question about interactive reporting.  I am trying to modify the "Update Chart Axis via Dynamic Content Container" protocol so that the work protocol returns a flash chart (as opposed to a png).

I have previously got this to work by doing the following:

1)  Form protocol - create and read from a cache to generate and initial flash bar chart.  Enter parameters for a new chart

2)  Work protcol - write a new chart to a cache based on the parameters passed to it from the form protocol

3)  Form protocol - reads from the updated cache and updates the chart in the dynamic content container.

When I try to to do this now and i attempt to update the chart i get the error - "Protocol returned no HTML or image result files"

I'm a little lost as this has previously been possible (however the protocol got lost during an update to the server)

Does anyone know of a way to run a work protocol and have it not return any html/images, just update a cache which the form protocol can then read from?

Many thanks,

Sam
