adding items to list in a tile definition using extension
Hello,
Is it possible when extending a tile definition to ADD some items to an
existing list (defined by parent tile definition) ?
I would like to do this :
My web pages have a top line that describe flow in app, something like
this :
home > catalog > search > result
I'm using a tile definition for this using the <putlist> and <item>
tags. But I need to set the full list on every definition. I would like
to use definition extends mecanism to have a "home" tile definition,
extend it in a "home.catalog", itself extended by a
"home.catalog.search" and so on. Every tile definition should only have
to ADD it's item to the existing list.
Is they're a way to do it ?

nice traditional solution...
make the stuff global, then it's sure to be accessible ;)
looks like a good way for toggling any parameters on and off
maybe should do a tile which does this in a generic way
..
just some thoughts..
<definition name="tile:toggle:base" path="toggleOnOffTile.jsp">
<put name="realExtends" value="tile:base" />
<putList name="pleaseToggleUs">
<item name="home" value="yes" />
<item name="catalog" value="furniture">
</putList>
<definition name="tile:search-result" extends="tile:toggle:base">
<put name="currentLocation" value="0.1"/>
</definition>

Re: adding items to list in a tile definition using extension
Posted by nicolas De Loof <ni...@cgey.com>.
OK, I've done it another way :
I put ALL items used in the webapp in a list :
<definition name="tile:base">
<putList name="locations">
<item vale="home">
<item vale="catalog">
...
and I extend it for every page :
<definition name="tile:search-result" extends="tile:base">
<put name="currentLocation" value="0.1.2"/>
</definition>
I use <c:forTokens> to get indexes in "locations" (0, 1 & 2) from
currentLocation" and print ${locations[index].value} in the JSP.
Nico.

suppose you should use another tiles:putList for each of the following
extensions and treat the values of them like they were in just one list.
but its evil! should be already in tiles ;)
also you have to decide if want to be able to override old items (then you
just have to implement it)
i.e. (without markup :)
definition name="justOne"
putList name="bla1"
item name="itemX" value="valueX"
...
definition name="alreadyTwo" extends="justOne"
putList name="bla2"
item name="itemY" value="valueY"
...
when using it search for blaN until you don't find that blaN anymor (using
logic:iterate and logic:exists and/or EL syntax)
