Re: Multiple images
Posted by Nathan Beemer <na...@gmail.com>.
In a nutshell, the way I did it was to implement IAsset for each
dynamic chart which then gets fetched by component id in the
IEngineService and asked to render itself to the given WebResponse.
Or put another way...
I have 2 dynamic chart images In my Foo.html page definition:
<img class="statGraph" width="235" height="135" jwcid="@Image"
image="ognl:clientStats" title="" alt="" />
<img class="statGraph" width="235" height="135" jwcid="@Image"
image="ognl:sessionStats" title="" alt="" />
I've defined
public abstract class ImageAsset implements IAsset
{
public void renderImage(OutputStream os) throws IOException ;
}
In Foo.java page class:
public ImageAsset getClientStats() { return new ClientStatsAsset(); }
public ImageAsset getSessionStats() { return new SessionStatsAsset(); }
Finally, in my ImageService (implements IEngineService):
public void service(IRequestCycle cycle) throws IOException
{
String pageName = cycle.getParameter(ServiceConstants.PAGE);
String idPath = cycle.getParameter(ServiceConstants.COMPONENT);
String option = cycle.getParameter(ImageAsset.OPTION);
IPage page = cycle.getPage(pageName);
IComponent component = page.getNestedComponent(idPath);
WebResponse response = cycle.getInfrastructure().getResponse();
try {
((ImageProvider) component).generateImage(response, new Object[]
{option});
}
catch (ClassCastException ex) {
exceptionReporter.reportRequestException("Fatal Error 0xa8", ex);
}
catch (Throwable ex) {
exceptionReporter.reportRequestException("Fatal Error 0x32", ex);
}
}

Re: Multiple images
Posted by Howard Lewis Ship <hl...@gmail.com>.
Generally, it is necessary to include some kind of id in the URL (as
context) that you can get back when handling the request. Using a
persistent page property is insufficient, since it will be "left" in
the value of the final rendering of the <img> tag, which is kind of
what you are seeing.
This is much easier in Tapestry 5, but the same rules apply: if a
component renders multiple URLs you should include in the URL that
specific id of the object associated with the rendering.

check the urls to the images... is it possible they're all the same?
