Hi Tim, yersterday we tried this one by removing all gradients, animations, rounded corners, but then the events were no longer propagated, so we could see some sort of button (very ugly though) but were not able to click them. As we understood the code in [1] when the engine says that VML is supported, a renderClass of VML-type would always be instantiated which in our opinion leads to javascript errors that kill something in the application. But we're no javascript experts (that's why we use RAP).
Would it be possible in your opinion, when we use IE 8 without enabled vgx.dll but with installed VMLViewer-Plugin? Maybe the service provider of our customers could implement this, assuming there's no known security issue.

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 Am 09.05.2014 08:24, schrieb [email protected]: 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/2964358 relating 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 ?
