3.96 ResetInput
Input components keep their local values at state when validation fails. ResetInput is used to clear
the cached values from state so that components retrieve their values from the backing bean model
instead.

sample demonstrates how to use RequestContext to do the reset within an ajaxbehavior listener.
Parameter of the reset method can be a single clientId or a collection of clientIds.
<p:inputText value="#{bean.value}"> 
<p:ajax event="blur" listener="#{bean.listener}" />
</p:inputText>
public void listener() {
RequestContext context = RequestContext.getCurrentInstance();
context.reset("form:panel");
}
Tip
p:ajax has built-in resetValues attribute to reset values of processed components during a request.

Getting started with Resizable
Resizable is used by setting for option as the identifier of the target.
<p:graphicImage id="img" value="campnou.jpg" />
<p:resizable for="img" />
Another example is the input fields, if users need more space for a textarea, make it resizable by;
<h:inputTextarea id="area" value="Resize me if you need more space" />
<p:resizable for="area" />
Boundaries
To prevent overlapping with other elements on page, boundaries need to be specified. There’re 4
attributes  for  this minWidth,  maxWidth, minHeight  and maxHeight. The  valid  values for  these
attributes are numbers in terms of pixels.
<h:inputTextarea id="area" value="Resize me if you need more space" />
<p:resizable for="area" minWidth="20" minHeight="40" maxWidth="50" maxHeight="100"/>
Handles
Resize handles to display are customize using handles attribute with a combination of n, e, s, w, ne, 
se, sw and nw as the value. Default value is "e, s, se".
<h:inputTextarea id="area" value="Resize me if you need more space" />
<p:resizable for="area" handles="e,w,n,se,sw,ne,nw"/>
Visual Feedback
Resize helper is the element used to provide visual feedback during resizing. By default actual
element itself is the helper and two options are available to customize the way feedback is provided.
Enabling ghost option displays the element itself with a lower opacity, in addition enabling proxy
option adds a css class called .ui-resizable-proxy which you can override to customize.

Effects

listener defined, it will be called by passing an org.primefaces.event.ResizeEvent instance as a
