Lighting aura:event not firing, or handler not executing

Hi there.

In my lightning app I have a few components:
  • one component has a ui:inputSelect and registers an event. the ui:inputSelect has a change attribute that fires a function, wherein the selected text (an ID) is put in an event and fired.
  • one component that handles the event, is an aura:iteration list of a component that, on handling the event, should retrieve a list of items where a master-child lookup is the sent ID of the master object. This then displays all those child objects.
  • the other component that handles the event, has three inputText fields, that are supposed to display the other fields of the master object
The problem: either the event seems to not be fired, or the handlers seem to not be activated.

I put console.debug's, alerts and component.set("v.testmessage", "fired") 's in the handlers but they never execute.
I then put one of the handlers as the init-handler and then it did execute the handler (with an undefined ID since the event hadn't yet been fired, which is reasonable).

I have triple-checked the event name, event type and handler action, everything matches. I have no compilation problems, I have no errors when I am using my app. 
I also have no response whatsoever from my event. Any ideas?

**Registering component** 
<aura:component controller="PrefixMasterHeaderSelectorController">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

Skinny Table Needed

I'm posting in the forum because I asked usign a case and I got kicked.

I need the creation of a skinny table because I'm getting timeout in a scheduled query. I'm getting the message:

First error: SQLException [common.exception.SfdcSqlException: ORA-01013: user requested cancel of current operation

select /*Apex.Class.BatchApexMetricSummarization.start: line 31*/ *
from (select "Cust_ID__c",
"Id"
from (select t.deleted "IsDeleted_...

That is happening because is taking more than 10 minutes to proceed.

The query is simple:

Select Cust_ID__c From Metrica_Diaria__c Where Fecha_de_Metrica__c >= :dateFrom AND Fecha_de_Metrica__c <= :dateTo AND Summarization_Date__c = \'N/S\' Order By Cust_ID__c limit 50000

When:
  • dateFrom = today - 3 months
  • dateTo = today - 1 day

Fecha_de_Metrica__c and Summarization_Date__c are indexed field, so I don't have much to do here.

Metrica_Diaria__c is a custom object with 1.942.440 records and I'm query 500k approximately (overall target records).

The fields that I need are:
Cust_ID__c, Fecha_de_Metrica__c, Summarization_Date__c, Cuenta__c

The question is:
How I get the Skinny Table created?

Thanks

Issue with Apex Class Coverage

I tried without success to fix this SF's issue. I edited a class that was not longer used (couldn't delete it) to reduce useless code, but SF is showing me the same lines count than before. I know that Salesforce save metadata of apex classes in an object, but we cannot access to that table. I attached a screen showing the issue, I don't know what can I do to fix it. I fear that is affecting my org's apex coverage level:

Thanks for the help.

PD: I already tried to delete the class using the IDE, but It gave me an error related to AsyncApexJobs, like there was a job using that class, but really there was not.

Help needed to know what query is giving timeout

How can we identify which query is giving us timeout in a Batch Apex processing?  We have a Batch Apex that is aborting after N executions. The aborting is caused by timeouts in Oracle Database, and it happens randomly. We cannot see which query is causing it because SFDC doesn't allow you to see it in the UI. We checked them in the Query Plan Tool and none involves tables with more than 150.000 records (low volume). (We have already read about Query Optimizer and High Volumes.)

I already logged a case, but of course they sent me to the forum, even when the only people who can tell me what I need are them.

Sonam, could you help me find the query?, this issue has been burning for some time now, thank you!

"Invalid user identifiers" when sending chatter message to portal user from apex

I have in my code: ConnectApi.ChatterMessages.sendMessage('Hello World', '[portal user id]');

But it fails saying "Invalid user identifiers"

This is a community user.  Does that mean they can't receive direct chatter messages? This same piece of code works fine for internal users.

Apex Job Aborted By User

Hi, we've just tried to ask salesforce via a case why an Apex job is marked as aborted by User (when each User denies such knowledge) and they seem to think it's a developer request and pointed us here.

Case #11212305
Original request:
Hi, please can you let me know why the batch was "Aborted By User" as no one has aborted a job. Also can you state what the underlying error is - if there is one?
Apex Job Id: 7072000000vWcRV

Since this is an internal issue, I'm assuming the only folks who can help us the Salesforce employees who patrol these boards?

Thanks in advance.

Trying to access to attachment get: Error ID: 834158013-11877 (63307295)

Hi, I'm trying to do something really simple that already did in other times, i'm doing a link to an attachment from my site, for example:

http://mysiteurl/servlet/servlet.FileDownload?file=00PE000000ChmGbMAJ

And i get "An error has occurred while processing your request. We apologize for the inconvenience. Error ID: 834158013-11877 (63307295)"

I can't know what is happening, I have other attachments linked in the same way and they works fine. The parent's object is new, I'd already give access to the object in the site's profile (view all).

Please, I would like if someone from SFDC's support could tell me what is happening in the background. If I create a case, they will send me back to the forum.

Thanks a lot.

Issue trying to access to a VF Page in Summer 14

Hi, I'm having an issue in Summer 14' organization that I had never seen. When I try to access a Visualforce Page like I usually do, I get a blank page.


For example, If I try:

https://virtualseller-6602.cloudforce.com/apex/testVF

I get:

https://virtualseller-6602--c.na17.visual.force.com/visualforce/recsession?sid=00Do0000000K6Rm!AXftXXXXXXXXJcxkUqKgCyAJeBmZzgMXTYBMp0KkIDAgbUtzLBRv2J18hTjc4qTS4RU2D9XtlyeOtUl1sT3Stb712h7h&inst=o&cshc=0000000O8H60000000K6Rm&retURL=https%3A%2F%2Fvirtualseller-6602--c.na17.visual.force.com%2Fapex%2FtestVF

And stops there.
It seems that something goes wrong with the session validation and I don't know why. It's happening with ALL the Visualforce Pages of the org.

Is anyone having the same problem/issue?
Thanks
