T5: PageLink on img tag
Hi,
I'm doing some data rendering using JFreeChart, for which I've created a
Tapestry page "PlotImage" which renders images and returns them as
StreamResponses of type PNG or PDF. I'd like to use this to render
inline <img> tags, e.g.:
<a href="#" t:type="pagelink" t:page="plotimage"
t:context="literal:hepdata-p7521-d2-x1-y1_600.png">
<img src="#" t:type="pagelink" t:page="plotimage"
t:context="literal:hepdata-p7521-d2-x1-y1_300.png" />
</a>
(only without the "literal:" bits in practice: these contexts will be
generated dynamically). The result isn't quite right, though: the <a>
link to the full-size image functions just fine, but the pagelinked
<img> renders the pagelink as an "href" tag... not very useful: I'd
hoped that there would be special PageLink treatment for <img> tags that
would use the "src" attribute rather than "href". So, *is* there a nice
way to dynamically create <img> src attributes pointing to Tapestry pages?
Thanks,
Andy

Hi Andy,
Have a look at this thread, I posted a solution that is similar to your
requirements.

What you're asking is very reasonable, IMHO. Please post a JIRA about it.
In the mean time, you can generate the URL injecting the
PageRenderLinkSource service and invoking
createPageRenderLinkWithContext(Class, Object[]).

Incidentally, I'm doing exactly the same. Rather than trying to use a
a page link, I'm just creating an action link then sticking the value
to img tag's src attribute (as described at
http://wiki.apache.org/tapestry/Tapestry5HowToCreatePieChartsInAPage).
This works fine for me.
