For my current project i need to offer the user the possibility to write text with images that he can insert into the text. With the built in RichTextArea of vaadin7 i can write the text but won't upload / insert images from the local drive of the user just specify the url of the image where it is available on the web. How can i hook into the "Insert Image" Function of the RTA? Or are there any other ways to realize it?
I would suggest that you try the Vaadin add-ons directory, and specifically for your use case I would try editors such as CKeditor
