Vaadin 10 RichTextEditor problem

Flow
1

Hi.

I can’t use RichTextArea. When i declare a variable page in browser shows me:

	There was an exception while trying to navigate to '' with the exception message 'Unable to create an instance of 'com.vaadin10.MainView'. The constructor threw an exception.'
java.lang.IllegalArgumentException: Unable to create an instance of 'com.vaadin10.MainView'. The constructor threw an exception.

Caused by: java.lang.RuntimeException: Uncompilable source code - cannot find symbol symbol: class RichTextEditor

So the RichTextEditor class is not found (not on the class path). What Vaadin version are you using? If Vaadin 13 beta1, switch to beta2.

Vaadin 10

I did all what i could - searched in maven repositories and added but didn’t work

RichTextEditor is introduced in Vaadin 13 and is not part of the free version, see https://vaadin.com/releases/vaadin-13#rich-text-editor

5

Although in vaadin 10 docs RichTextArea was represented

AFAIK the RichTextArea component was never available for Vaadin 10. It was planned for Vaadin 12 (12/2018).

It is included in Vaadin 13 as RichTextEditor.
