([VE][404] and [VE][xmlwf]) && operator assumed as bad ampersand

Error [404]: "character X is the first character of a delimiter but occurred as data"


In the following tag, both && operators in the onclick event are being treated as bad ampersands, generating both errors in the subject:

<input type="submit" name="confirm" value="Entrar" onclick="return this.form.entered_user.value!='' && this.form.entered_password.value!=''" />
