so you want to generate a link in a grid and dependending
on a parameter have a mixin attached.
you can solve it by using a delegate that is directed to a block
(or component) that in one case contains a simple eventlink and
in the other case contains a eventlink with the attached mixin
<t:block id="eventLink"><t:eventlink /></t:block>
<t:block id="eventLinkWithMixin"><t:eventlink
t:mixins="jsmixin"/></t:block>
that's one of the drawbacks you have, when following the static
structure, dynamic behaviour paradigm. you always have to
have all posibilities defined in advance. and from my point of
view it's not always that bad.
hope it helps

Betreff: Re: Generated links in a loop
Hi Kristian,
Reading through what I wrote, I guess I could be clearer, here is more
detailed explanation.
I create a model that I attach to a component (a type of custom grid), its
populated with database records... some of the columns in the grid need to
be links, and I can create the various types of links (event, page, action
etc.) as I wish... so far this is all straightforward.
Occasionally I need to generate links that have a mixin attached, my links
are obviously generated in a loop, and on the fly from the database data.
I am not using a markup writer, but I guess that could be the solution...
only that would mean also writing out the mixins JavaScript, very
possible, but I would like to avoid it if there is a better way.
When generating an event link it would be nice to be able to attach an
'attribute' (thanks for correcting) to specify a mixin, I know of no way
to do this dynamically when generating links via Tapestry??
Cheers,
Peter

Subject: Re: Generated links in a loop
hi peter,
i don't understand your problem entirely...
but have you considered using a EventLink
component instead of generating the link
manually. then you can easily attach a mixin
that renders some javascript using the
PagerRender service.
or do you mean a <a> attribute by saying link property?
in this case you can use the MarkupWriter from the render
event methods to add additional attributes... even in mixins
void beginRender(MarkupWriter writer) {
writer.element().attribute(,...);
}
i guess i'm missing something :)

Betreff: Generated links in a loop
Hi!
Is it possible to attach a mixin on the fly to a 'generated' link?
I wanted to use component resources:
Link link = resources_.createEventLink(linkId, new Object[]
{param1,param2}); for generating the link, but there doesn't appear to be
a way to attach a link property? I feel like I am missing something
obvious ? ...the only way I know of that might work is using
renderInformalParameters and writing the mixin JavaScript into the page...
hmm don't like that too much, is there a better way?
Thanks,
Peter
