Hi Chris,
thanks for your sift answer
I think this is the right direction. I am just stuck with a very – probably
stupid – problem. I included all relevant paths that I can think of with:
define([ "jquery", "t5/core/dom", "t5/core/ajax", "t5/core/utils" ]
the function looks like this:
var buildUrl = function(link, params) {
return utils.extendURL(link, {
params : JSON.stringify(params)
});
};
Where the calling is:
var url = buildUrl(callback, {
'action' : 'follow',
'userid' : '11239528343'
});
but in Firefox console I get still
TypeError: extendURL is not a function
buildUrl()
myBarRender.js:56
<anonym>
myBarRender.js:30
jQuery.event.dispatch()
jquery.js:137
jQuery.event.add/elemData.handle()
jquery.js:126
jQuery.event.trigger()
Any Idea?
Thanks a lot
Janko

Betreff: Re: Problem sending data from a JS Element back to Tapestry
you cannot expect that your parameters end up as event context (unless you
encode them into your url in that way).
I've had success using:
var url = buildUrl( setupDialogLink, params ); ajax( url, {
success: function(){ ... }
});
var buildUrl = function( link, params )
{
return utils.extendURL( link, { params: JSON.stringify(params) } ); };
Where ajax/utils are those from t5/core/ajax / t5/core/utils
The handler on the server side looks like this:
handlerName( @RequestParameter( "params" ) JSONObject json )
HTH.
