Dear reader,
We have a problem with the SSRS 2012 map chart when viewed in the browser as a subreport.
When the report is directly viewed (not as a subreport) everything works fine. The map chart gets displayed.
When the report is viewed as a subreport within a other report the map isn't visible anymore (you only see the borders around the map and a red cross at the left top using IE9).To make this issue even better: In the subreport we have 2 maps; the first doesn't get displayed in each case; the second however is being displayed fine. The second map chart in the subreport is a copy of the first (i compared the underlying XML of both maps; it's exactly the same except for another data field that it's being shown). Exporting the map in the report as PDF or MHTML (when viewed as a subreport) goes well in all occasions; the only problem we have is when its viewed after rendering in the browser as a subreport!!
The reportserver logs don't show anything; it also doesn't seem te be a browser problem (get the same results on Firefox). Any advice is welcome!
On request I can send more information about this issue.
Kind regards,
Ron Verhoeven
