Literate Aspects
5 years ago Mar 23, 2017 6:48pm

Please, any suggestions as to why this occured and the solution is greatly appreciated.

I am at step 7 of  https://vaadin.com/docs/-/part/framework/tutorial.html
7. Connecting the form to the application

A screen shot is included that displays the error.  I have tried four times in following the video tutorial USING Vaadin 7 Project.

The log is below:

Eleazar Alfriadez: Podrian dar solucion al siguiente error, gracias

Are you from Spain? I bet you are.

I think this forum is meant for international users, so it is based in English. It is probably a bit of bad manners to write here in a different language. You have a Spanish forum more suited for non-English speaker users, where you can use your own language, which I'm sorry is not as "universal" as you think (other non-Spanish native speakers Spaniards probably know what I mean).

Also, try to be a bit more descriptive than simply pasting the full exception you got in a random thread. For instance: what were you trying to accomplish? Which was the context? Can you post a snippet of your code?

Furthermore, looks like you are blaming the Vaadin staff for that error, when in fact the fault is caused by yourself...
