While trying to access a dashboard after Siteminder SSO, the following error is thrown by mapviewer. However, its not coming when Siteminder is bypassed.
"Unable to download resource files from Oracle Fusion Middleware MapViewer. Please contact your administrator if this problem persists"
I don't know how SSO works so can't suggest a solution.
However the cause is that the oraclemaps.js is not accessible.
i.e. the BI dashboard page (with a map view) is requesting the file
/mapviewer/fsmc/jslib/oraclemaps.js and that is not accessible.
I have no clue why this happens with SSO but not without SSO.
Someone in the OBIEE forum might however.
