How to solve the Problem?
Hi all,
Ive got the following error:
Widgetset does not contain implementation for org.vaadin.teemu.wizards.WizardProgressBar. 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:
-Unrendered UIDL
-org.vaadin.teemu.wizards.WizardProgressBar(NO CLIENT IMPLEMENTATION FOUND) id=PID49 width=100.0% complete=false
-steps
-step caption=Welcome! completed=false current=true
-step caption=AGB's completed=false current=false
I recompiled the project, and I am using Navigator7 (so I have changed the servlet-class in the web.xml).
Could you please give me a hint how to solve this problem?
Best regards Florian Köhler
Did you recompile your widgeset after adding the addon ?
If you are using eclipse, look in the toolbar for an icon with a gear and the vaadin logo on it.
Oh thanks, it whas the "suggestion text field", and another addon, it seems that they had trown an error while the gwt had tried to compile them....
After removing the concerning addons and recompiling everything was working :-)
Thanks a lot! Have an nice day!
