Hi.
It should be possible to modify any RAP version to work without VML,
assuming the "classic" theme is used (as it doesn't use
gradients/rounded borders) and no Canvas widgets are used.
The ProgressBar widget is also problematic, but could be modified to
work without VML.
However, these changes aren't trivial and I can not give you some
easy-to-follow tutorial to implement them. I would have to do it myself
and probably need at least few days for that.
Greetings,
Tim

Hello,
we are using RAP 1.5.2 for about 7 applications among 400 customers.
Most of them still stick to Windows XP and therefore to IE 8 (because
our customers are mostly bank institutes who depend on external IT
service provider).
Recently a security vulnerability in the Microsoft VML-Library came up
which was fixed by an out-of-band patch
(http://support.microsoft.com/kb/2964358relating to
https://technet.microsoft.com/de-de/library/security/ms14-021).
Instead of using this patch the service provider of our customers
suggested disabling the VML-capabilities of IE by unregistering the
dll "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll". This makes
every RAP-application non-functional on IE < 9, because it tries to
initialize an org.eclipse.rwt.VML in org.eclipse.rwt.GraphicsUtil, if
the engine reports to support VML [1].
As far as we can see, IE up to version 8 reports as engine name
"mshtml", which in org.eclipse.rwt.Client leads to returning true in
function supportsVml. [2]
So the question is: Is it possible to get around this with
a) not having the customers upgrade to IE >= 9
b) not having the customers use a different browser
c) not having the customers to re-enable the vgx.dll
?
Best regards
