might the url encoding within t:jshowurl incorrect?
Example:
<t:beanprocessing>
<t:jshowurl trigger="#{d.EditorTestUI.showUrlTrigger}" url="http://www.greenfield-solutions.de/#!4711" />
</t:beanprocessing>
The "#" is encoded to "%23", which make the URL invalid for Vaadin-use.
For RFC 3986 this should be a valid character:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~:/?#[]@!$&'()*+,;=
...have to admit: what I said was OK, but only for the query parameter part of the URL. You were talking about the URL-address-part - and there "#" has a meaning...
So: the transformation is not done any longer for "#" in the URL. Available with next update.
