browser support

[claudiobosticco]

Hello, I was wondering which old versions of Internet Explorer SmartClient still supports, and how the new skins are degrading on them.

I've got an old machine with IE8 at hand, so I tried to access the showcase, but the page remains blank with errors.
This is the stacktrace from the developer console while trying to open https://www-demos.smartclient.com/sm...test/showcase/
SmartClient Version: SNAPSHOT_v12.0d_2018-02-16/AllModules Development Only (built 2018-02-16)

and this while trying to open https://www-demos.smartclient.com/sm...ease/showcase/

We've made changes that will be in tomorrow's nightly builds (dated 2018-02-22) to address your inability to load those pages in IE8. However, note that lesser problems, such as glitches in how some widgets may be drawn, likely won't be fixed due to IE8 being out of support by Microsoft for quite a while now.

Just a further note - the only actual problem here was that these pages now use the Tahoe skin by default, which doesn't support IE8.

Thanks, now I see that the pages are loaded. There's still that error

'Object doesn't support this action'
    in https://www-demos.smartclient.com/googleAnalytics.jsp

but I don't know if it does matter.

Actually the showcase now loads even if I switch to Tahoe skin, only with a warning in the developer console, but then the showcase becomes so slow that's unusable (ie: a minute to open nodes in the featureExplorer_exampleTree).

if it's not supported maybe an explicit isc.warn() or a redirect page would be better?

We've updated the Showcases to issue a warning and refuse to load any flat skin if the browser doesn't support it - such as IE8.
