hi Juri
I did it the same way as you did and it worked fine. Even more : I
didn't even see lines in http header (???).
However, it doesn't fit my use case : I need to get the link to the
file to embed it in a javascript. Previously I did it this way :
PageParameters parameters = new PageParameters();
parameters.add(AMChartDataProviderPage.DATA_KEY, set.getDataId());
return RequestCycle.get().urlFor(AMChartDataProviderPage.class,
parameters).toString();
however I don't know how to do it with what you provided...
