Hi,
I have developed a vaadin application that runs fine, however now I also would like to integrate it into a rich-client application that supports
displaying web pages inside the rich client in a subwindow
. To achieve this the application uses the
Microsoft IE browser activex control
(see https://msdn.microsoft.com/library/aa752040(v=vs.85).aspx ).
The problem is now:
The vaddin application is not fully working when used within the webbrowsesr activex control.
Initially it was even worse, but then I found out that a webbrowser control by default runs with enabled webbrowser compatibility mode and by default it identifies as IE7 - very bad for vaadin, I know. Then I found an option to disable that and make the webbrowser control use (or at least behave like) the IE version installed on the client (see https://blogs.msdn.microsoft.com/patricka/2015/01/12/controlling-webbrowser-control-compatibility/ )
After changing the registry accordingly (set the value proposed in the link above) in the beginning everything seemed ok as vaadin application was loading correctly and first page was displayed correctly and working. But then I found some issues.
Currently biggest issue is that
autocomplete in combobox widgets is not working
(and even pressing cursor/arrow-down-key does not popup with the combobox entry list). However, the data is there - if I click on the arrow right beside the text input field the list comes up and I can choose a value.
Anybody who has experience with this or can give me a hint what I could try to solve the problem?
Best regards and thanks in advance, Martin.
