From the addInit() JavaDoc, specifically the first parameter:
functionName the name of the function (on the client-side
Tapestry.Initializer object) to invoke.
addInit() just invokes functions that are part of the Tapestry.Initializer
object. Try this instead:
Tapestry.Initializer.load = function(jsonObject){
...
//acces to the variable in JSON
errorText.text(jsonObject.m2)
}

Re: Difference between renderSupport.addScript and JSON
addInit(function, JSON Object)
Posted by Javix <s....@gmail.com>.
One more question:
How to trigger the exectution of js function. For exmaple, before the code
was like that directly n the tml page:
<t:if test="error">
<div class="info i-error">
Some hard-coded meessage
</div>
</t:if>
So I tried to apply your technics, but the js function is never loaded (I
have no errors displayed when submitting the form):
@IncludeJavaScriptLibrary(value = { "context:/static/javascript/password.js"
})
public class ForgottenPassword {
...
@Property
private boolean error;
@BeginRender
void addJsLibs() {
if (error) {
JSONObject jsonObject = new JSONObject();
jsonObject.put("m1", messages.get("js.error.password.epmpty"));
jsonObject.put("m2",
messages.get("js.error.confirmed_password.empty"));
jsonObject.put("m3", messages.get("js.error.password.not_matched"));
jsonObject.put("m4", messages.get("js.error.email.empty"));
jsonObject.put("m5", messages.get("js.error.email.wrong"));
renderSupport.addInit("loadPass", jsonObject);
}
}
...
}
And in JS file password.js:
Tapestry.Initializer.load = function loadPass(jsonObject){
..
passError.html(jsonObject.m1);
...
}
loadPass(jsonObject);
Why?

Finally I got it working by adding as you told:
Tapestry.Initializer.load = function load(jsonObject){
..
errorText.text(jsonObject.m1)
}
and ot in the very begining of the call:
jQuery(document).bind(Tapestry.ZONE_UPDATED_EVENT, function(e){
//load(m1,m2,m3,m4,m5,m6,m7,m8,m9,m10,m11,m12);
load(jsonObject);
});
It works, THANK YOU!

Re: Difference between renderSupport.addScript and JSON

It didn't work:
Oups ... org.apache.tapestry5.runtime.ComponentEventException: A component
event handler method returned the value
MultiZoneUpdate[{page=org.apache.tapestry5.corelib.components.Zone@1799a64,
May it's because in the javascript file the call to the load fucntion is
made lie that:
jQuery(document).bind(Tapestry.ZONE_UPDATED_EVENT, function(e){
//load(m1,m2,m3,m4,m5,m6,m7,m8,m9,m10,m11,m12);
load(jsonObject);
});
...
Tapestry.Initializer.load = function load(jsonObject){
//function load(m1,m2,m3,m4,m5,m6,m7,m8,m9,m10,m11,m12){
errorText.text(jsonObject.m1)
...
}
