Description
The baseform tag allows you to create a web
form. The data represented by components that are enclosed in the
form tag can be sent to the server using the submit
tag. Each form component, such as checkbox,
combobox or radiogroup must have
a name. The data is submitted as name-value pairs, using the name and
value of the component.
baseform provides no layout for its
contents. If you want a simple automatic form layout use the
form tag.
Provides component grouping for a form. A form is typicaly a
collection of UI elements where each represents data from the user
that will be submitted to the server as a request.
Baseform supports listening for a changed value. A value is
changed if the value of any of its baseformitems were modified at any
point.
