I am trying to create a sample CRM for a student project. Currently, I am utilising springboot and vaadin in the STS4. I am using components from their cookbook and the vaading crm tutorial and the their bookstore sample projects from github as templates (i am kind of mixing up the elements of the two, perhaps my lack of understanding is what causes me this trouble). In the form for submission, the following errors are raised in lines 67 and 49: “Syntax error on token “;”, { expected after this token” and “Syntax error, insert “}” to complete Block”. I am adding my complete form for your inspection, hopefully, someone can explain to me, what is causing the error. Here is “my” code:
