X-Application 4.1.1 for environments without JavaScript

, ,

Hi,

Tamino X-Application uses JavaScript for actions like submitting the content of forms to the server and committing changes. In some environments JavaScript is disabled by default i.e. X-Application applications do not work as expected. Attached you find a workaround for building an X-Application application without JavaScript code, i.e. browsers without JavaScript will be able to use such an X-Application.

Hello,

thanks for this contribution. If there are no arguments against the solution Jan introduced, we will take over the code and make this solution available for a next version of X-Application.

Please give me feedback to this topic if anyone knows any reason why we should NOT adopt Jan’s idea.

Many thanks.

Bye,
Christian.
