Hi all
Currently got a support ticket on-going with ESRI but slow/no progress so throwing it open to the floor ??? any input greatly
appreciated! Bear with me, it is a weird one???
Running: Cognos 10.2.1 FP2, EM4C 4.3.2 (+ 10.2 compatibility fix), ArcGis 10.2.1
Current reporting structure:
1. Entry Report ??? Cognos report (no ESRI content) with prompt page and summary totals output page, with several Cognos drill-throughs defined (passing required/optional parameters) to all of the following???
2. Report A ??? Geo Level 1 (Shape Layer): Cognos report with list and ESRI map (no parameter page) ??? EM4C drill-through on map to Report B, Cognos drill-throughs back to Entry Report and Cognos Excel List Report
3. Report B ??? Geo Level 2 (Shape Layer): Cognos report with list and ESRI map (no parameter page) - EM4C drill-through on map to Report C, Cognos drill-throughs back to Entry Report and Cognos Excel List Report
4. Report C ??? Geo Level 3 (Shape Layer): Cognos report with list and ESRI map (no parameter page) - EM4C drill-through on map to Report D, Cognos drill-throughs back to Entry Report and Cognos Excel List Report
5. Report D ???Geo Level 4 (XY Layer): Cognos report with list and ESRI map (no parameter page), Cognos drill-throughs back to Entry Report and Cognos Excel List Report
This reporting suite works just fine in IE8, IE10 and Chrome. However, client then changed requirements and wanted to enter the
suite at Report A ie display map report for all available areas. Attempted this in two ways:
a) Report view to Report A with necessary parameters defined and report view not to prompt user for parameters
b) Duplicate report but with no parameters required
With both reports I immediately encountered a major issue. The Cognos report would run in IE, the list populate with data, but the map would not render; IE8 displayed a black block in place of the map, IE10 nothing at all. Yet the either report would still run fine
in Chrome.
So then I tried running Report A directly. As expected, Cognos automatically created a parameter page, but after specifying
required values (or leaving blank - all prompts at this level are optional) the same results were encountered ??? IE8 black block, IE10 white block, Chrome OK.
Numerous attempts to rebuild the report resulted, all with the same outcome. However, on several occasions I thought it was
resolved as the rebuilt report would run for a period of time, but then ultimately the same results were experienced. Could this be
some sort of caching issue? Regularly clear IE browsing history etc so would have to be something server-side.
During the rebuild process the cause of the issue became evident; adding the drill-through broadcast action from Report A to
Report B in ESRI Maps Designer killed the map functionality. Up to this point the map would render fine in all browsers, but the new drill-through code would kill IE functionality (still working in Chrome!). Why would this bit of code kill the map ??? is it something to do with null or optional parameters being handled incorrectly?
Also, all these rebuilt reports would still run in IE if accessed via a drill-through from another Cognos report, just as we experienced originally.
And this is where we are at some two months after the issue was originally encountered. Has anyone else experienced similar
issues with EM4C drill-throughs, or encountered the black/white screen in place of a map in IE? Appreciate IE8 is no longer
supported, but I need to handle all browsers as user base could be using any of these, and issue is in all IE10 as well.
All view/opinions welcomed.
Many thanks
Gary
