Now that the SOURCE feature is implemented, do you know if it can be used to add Javascript and Java/JSP snippets in the source so they stick around the HTML source? This allows us to use the source generated by the editor in a JSP documents that are then interpreted when rendered in our web app.
We have lots of things like this in our current HTML (from ckeditor 4 under vaadin 8) editors that we use to generate JSPs for runtime:
<% _put your custom java code here_ %>
or
<% if ( esf.isEditMode() ) { %> _put the optional HTML here to show only if the document is being filled out and/or signed_ <% } else if ( esf.isReviewMode() ) { %> _put the optional HTML here to show only if the document is being reviewed before submitting_ <% } %>
