Well, rename computeUrl() to getYouNameIt() and access it using
ognl:youNameIt from your template or page specification.
I compute the url in the html in a for loop.
So the stuff I miss is how to access "infrastructure:contextPath" from ognl.
I did this
ognl:page.engine.infrastructure.contextPath+'/Public/flags/'+localeItem.language+'.gif'
and it's working ! Great.

Let Tapestry inject the infrastructure:contextPath object like
@InjectObject("infrastructure:contextPath")
public abstract String getContextPath();
Then write some computeUrl method similar to this one (just typed
this in,
no guarantee that this will work).
public String computeUrl() {
String locale = getLocale().getCountry().toLowerCase();
return getContextPath() + "/Public/flags/" + locale + ".gif";
}
Thank you Ulrich,
This is the Java way, what is the Ognl way ? To use in Html and/or
Jwc files.

Hello,
I could not find how to compute a url ...
It is for a component which give the user the possibility to change
his
locale by clicking on a image (country flags).
Urls should be like : /theApp/Public/flags/fr.gif
There is 2 dynamics parts :
* the application context : /theApp
* the available locale code : fr
like : <context>/Public/flags/<localeCode>.gif
I thought about <asset name="xxx" path="context:xxxx" /> but it is not
possible because path attribute started by "context:" could not use
ognl
expression.
Also thought about <img jwcid="@Any" src="ognl: page.context +
'/xxx/' +
currentLoopItem + '.gif' " /> but "page.context" does not exists.
I really could not find how to compute the <context> part of urls.
Have you got any idea please ?
Thanks
cyrille
