[t5.2.6] Possible bug related to prototype
Unfortunately I don't have enough information to tell but here is all what I
think that matters.
I have an ajax form. On it's success, I return a mutli zone update object:
@OnEvent(component = "trendForm", value = EventConstants.SUCCESS)
Object formSuccess() {
MultiZoneUpdate mzu = null;
switch (testType) {
case DNS:
errorResponses =
dnsResponseDao.getScheduledResponsesWithErrors(tclRequest.getId(), dFrom,
dTo);
mzu = new MultiZoneUpdate("chartsZone", this.dnsCharts);
break;
case RADIUS:
errorResponses =
radiusResponseDao.getScheduledResponsesWithErrors(tclRequest.getId(), dFrom,
dTo);
mzu = new MultiZoneUpdate("chartsZone", this.radiusCharts);
break;
}
if (errorResponses != null && errorResponses.size() != 0) {
errorResponsesLastIndex = errorResponses.size() - 1;
return mzu.add("testErrorsTableZone", testErrorsTable);
}
return mzu.add("testErrorsTableZone",
testErrorsTableZone.getBody());
}
So basically if there are errors, I return a block in the "
testErrorsTableZone". But if there isn't, I clear it by returning the zone's
body.
Here is a part of my .tml file:
<t:zone t:id="trendFormZone">
<t:form t:id="trendForm" t:zone="trendFormZone">
<tr>
<td><t:select t:id="testType" t:validate="required"
t:zone="testSelectZone" />
</td>
<td><t:zone t:id="testSelectZone">
<t:select t:id="tclRequest" t:value="tclRequest"
t:model="testNamesModel" t:encoder="testNameEncoder" t:validate="required"
/>
</t:zone></td>
<tr>
<td colspan="6"><t:zone t:id="chartsZone"
t:update="slidedown" /></td>
</tr>
<tr>
<td colspan="6"><t:zone t:id="testErrorsTableZone"
t:update="slidedown" /></td>
</tr>
</table>
</t:form>
</t:zone>
<t:block t:id="testErrorsTable"><!-- html here --></t:block>
<t:block t:id="radiusCharts"><!-- html here --></t:block>
Here is what happens, when the form success *returns blocks*, one into each
zone, everything works fine.
But when I return "testErrorsTableZone" 's body to itself and a block to the
"chartsZone" zone, ONLY the zone updated with it's body is updated but the
other zone, which is updated with a block (i.e. chartsZone), doesn't !
Using firebug I found that JSON responses are returned fine. So I debugged
the javascript calls and found that the following method catches an
exception saying "element.down() is null". After a quick search I got a hint
that this happens because of the "t:update" effect. So I removed the effect
and left it to use the default and everything worked !
var Enumerable = (function() {
function each(iterator, context) {
var index = 0;
try {
this._each(function(value) {
iterator.call(context, value, index++);
});
} catch (e) {
if (e != $break) throw e; <<<<<<<<<<<<<<<<<<<<
}
return this;
}
I think the MOST important thing here is that the exception catched at the
line with the arrows, isn't shown at all to the user (me). It just doesn't
work. Nothing is logged in the javascript console and nothing shows up in
the browser !!!
I have no idea why this happens exactly. I just need to know if it's
protoype's or tapestry's issue
Thank you all for your time.

I forgot to mention that the JS snippet exists in prototype.js, line 828.
