Seems to me like D2W integration of long response pages is your issue here and the d2wcontext is getting lost. CCAjaxLongResponsePage knows nothing about D2W for a start, neither the nextpage controllers being used there. The jasper task is a background Callable task that returns a File result. The Jasper example project is not a D2W project. So, at this stage I have to defer to the D2W experts on the list for advice on integrating a background task with a File (to be downloaded result) into a D2W scenario.
The iReport MUST match the JasperReports version in this project. You have been warned.
Look in Libraries directory of this project for the jar named something like jasperreports-X.X.X.jar.
That file has the current version number.
Currently Wonder version is at 3.7.4. It will probably stay that way for a while. Jasper has many other dependencies and those dependencies are used across other Wonder projects .... iText for example. So it is not just a case of drop the latest jasper and all its dependencies into Libraries.
