data is an alias for value. Do you have them both ?

[alpheratz-jb]

I have both:

<rich:paint2D id="paint2D" paint="#{paintBean.paint}" data="#{dataBean}"
 width="640" height="480" format="jpeg" cacheable="false"
 bgcolor="white" value="#{dataBean.value}" />

But:

if I use data="#{dataBean}", what method in the bean will be used to determine the caching key for server-side cacheing?

if I use value="#{dataBean.value}" to establish a key, how does the paintbean know where to get the actual data?

?

OK.

I have found a work-around: use mediaOutput.

THis has better control of caching, it seems:

<rich:panel header="Media">

 <h:selectOneMenu id="masterMenu"
 value="#{masterBean.selectedOption}">
 <a4j:support event="onchange" reRender="chartImage"
 ajaxSingle="true" />
 <f:selectItems value="#{masterBean.options}" />
 </h:selectOneMenu>

 <br />

 <a4j:outputPanel id="chartImage">
 <a4j:mediaOutput element="img" cacheable="false" session="false"
 createContent="#{chartGenerator.generate}" mimeType="image/jpeg"
 value="#{masterBean.selectedOptionLabel}"
 standby="Please wait...loading chart..." />
 </a4j:outputPanel>

</rich:panel>

Note that to allow for the image to be refreshed via AJAX, I had to wrap everything in an <a4j:outputPanel />.

Thanks for all the help, Sergey it is MUCH appreciated.

Cheers,

Alph
