Yes, you are. Not all Dijits have validation available -- that's why, for instance, there's both TextBox and ValidationTextBox. Textarea has no validation by default. Additionally, you'll need to tell the form to validate at the onsubmit event so that it does client-side validations prior to submitting. This has been discussed in a previous thread. > I've been scouring the ZF code and the Dojo API looking for clues as to why > this would or wouldn't work with a textarea, and I'll spare you the code > snippets, but it just seems like a (very strange) limitation of Dojo Dijits. > There's no validate() function for dijit.form.Textarea the way there is for, > say, dijit.form.ValidationTextBox or dijit.form.ComboBox.

Most validation constraints are meaningless for textareas as a result -- they're too restrictive. That said, it's simple to attach lambdas to events with Dojo, so you can certainly do so. > That having been said, I guess the way to go is to just put some custom > javascript in the oninit, onblue and onkeypress events of the textarea, like > Dojo has built in for those other Dijits.
