SimpleLayout and widget set

[Nils (Nils Weinander)]

I’m trying out the SimpleLayout addon
https://vaadin.com/directory#addon/simplelayout
to see if it can improve rendering performance in a very complex page and run into widget set problems.

First I get

Widgetset does not contain implementation for org.vaadin.simplelayout.SimpleLayout. Check its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:

org.vaadin.simplelayout.SimpleLayout(NO CLIENT IMPLEMENTATION FOUND)

so, I follow the instructions from here:
https://vaadin.com/directory/help/using-vaadin-add-ons/maven
(I had to update the gwt maven plugin and gwt dependency to 2.3 as well as I recently switched from Vaadin 6.5 to 6.8.

So, that step done the application UI won’t load, I get the following message:

Failed to load the widgetset: /VAADIN/widgetsets/no.anastazia.web.component.CustomWidgetSet/no.anastazia.web.component.CustomWidgetSet.nocache.js?1324308833669

trying the URL as mention in this thread
https://vaadin.com/forum/-/message_boards/view_message/18685
I get a 404.

Changing the servlet mapping does not help: neither /* nor /VAADIN/* produces a viable result.

But, strangely, when I check the contents of my war file, there is a file /VAADIN/widgetsets/no.anastazia.web.component.CustomWidgetSet/no.anastazia.web.component.CustomWidgetSet.nocache.js.

So, what am I doing wrong?

I tried this

as well, but get the same result.

I finally found the reason why I couldn’t get it to work: a simple, stupid capitalization typo… I had in one place written …Widget
S
et instead of Widget
s
et.
