public class Form extends HtmlForm
The <o:form> is a component that extends the standard <h:form> and submits to
exactly the request URI with query string as seen in browser's address. Standard JSF <h:form>
submits to the view ID and does not include any query string parameters or path parameters and may therefore fail
in cases when the form is submitted to a request scoped bean which relies on the same initial query string parameters
or path parameters still being present in the request URI. This is particularly useful if you're using FacesViews or
forwarding everything to 1 page.
Additionally, it offers in combination with the <o:ignoreValidationFailed> tag on an
UICommand component the possibility to ignore validation failures so that the invoke action phase will be
executed anyway.
Since version 2.1 this component also supports adding query string parameters to the action URL via nested
<f:param> and <o:param>.
Since version 3.0, it will also during ajax requests automatically send only the form data which actually need to
be processed as opposed to the entire form, based on the execute attribute of any nested
<f:ajax>. This feature is similar to partialSubmit feature of PrimeFaces.
This will reduce the request payload when used in large forms such as editable tables.
You can use it the same way as <h:form>, you only need to change h: to
o:.
This was available since version 1.6, but since version 3.0, this has become enabled by default. So just using
<o:form> will already submit to the exact request URI with query string as seen in browser's
address bar. In order to turn off this behavior, set useRequestURI attribute to false.
<o:form useRequestURI="false">
When you want to include request parameters only instead of the entire request URI with query string, set the
includeRequestParams attribute to true. This will implicitly set useRequestURI
attribute to false.
<o:form includeRequestParams="true">
This is the default behavior. So just using <o:form> will already cause the
<f:ajax> to send only the form data which actually need to be processed. In order to turn off this
behavior, set partialSubmit attribute to false.
<o:form partialSubmit="false">
The standard UIForm doesn't support adding query string parameters to the action URL. This component offers
this possibility via nested <f:param> and <o:param>.
<o:form>
<f:param name="somename" value="somevalue" />
...
</o:form>
The <f|o:param> will override any included view or request parameters on the same name. To conditionally add
or override, use the disabled attribute of <f|o:param>.
The support was added in OmniFaces 2.2.
In order to properly use the <o:ignoreValidationFailed> tag on an UICommand component, its
parent <h:form> component has to be replaced by this <o:form> component.
See also IgnoreValidationFailed.
Previously, the <o:form> also supported includeViewParams, but
this did after all not have any advantage over the later introduced useRequestURI and
includeRequestParams. Hence the includeViewParams is marked deprecated since 3.0.
