With the Spring 13 updates to the PDF engine, our visualforce PDFs no longer render images correctly. We reference static resources by their absolute url as follows:
(Yes I know we can use the $Resource syntax, but we've had issues with that in managed packages).
The above code results in a PDF that displays the "broken image" graphic.
I can also get it to work by disabling the PDF engine critical update for Spring 13. This is only temporary, however, as the updated will get automatically applied.
Can the engine be fixed so that we don't have to change all of our code to use static resources? Thanks.
I encountered some unexpected behavior with the save() method on the standard controller and just curious as to the reasoning behind it.
I have an instance of a StandardController for a new custom object. Calling the save() method successfully inserts a new record for the custom object. If you call save() again, it inserts another new record instead of updating the existing one in the controller's context.
Here's the basic code:
MyObject__c o = new MyObject__c();
ApexPages.StandardController sc = new ApexPages.StandardController(o);
// this successfully inserts a new record...
sc.save();
// this successfully returns the Id of the new record
// doesn't this mean that the record is in the controller's current context?
Id myId = sc.getId();
// shouldn't this update the record that is in the current context?
// it does not; it inserts a new record
sc.save();
Why doesn't the second call to save() update the record that was inserted in the first call to save()? It seems to be holding on to the reference of the object that was passed into the constructor. This would kind of make sense to me if the call to getId() returned null. At least it would appear that the context of the controller is consistent.
I have a visualforce page that has a custom component with rendered=false. In a different pageBlockSection, I have an inlineEditSupport component.
The problem is that when the page loads, it executes the constructor and methods of the custom component's controller. I wouldn't expect it to do that since rendered=false.
If I remove the inlineEditSupport component and reload the page, it does not execute the custom component controller.
How can I prevent my custom component controller from executing while keeping the inlineEditSupport on the page? Rendered=false does not seem to work.
Here is the (simplified) code:
1. Custom Component Controller
public class componentController {
public List<account> accounts{
get{
system.debug('in accounts getter');
return new List<account>();
}
set;
}
public componentController(){
system.debug('in constructor');
}
}
According to the VisualForce documentation here, you should be able to add a dynamic reference to a static resource.
The documentation provides this example:
"A very simple example of actual use on a page would be <apex:image value="{!$Resource[customLogo]}"/>, where you have a getCustomLogo method that returns the name of an image uploaded as a static resource."
This doesn't seem to work.
Here is my controller method:
public String getCustomLogo(){
return 'CompanyLogo';
}
and here is the line from my vf page:
<apex:image value="{!$Resource[CustomLogo]}"/>
I get the following error when trying to save the vf page:
We have a class that we need to upgrade to api version 18.0 to be able to use the new AggregateResult object. Once we changed the version to 18.0, we got a bunch of 'Method does not exist or incorrect signature' errors. The errors occurred both in the IDE and the UI.
We have a custom object that contains a number field named 'quantity'. It has 2 decimal places. The schema browser indicates that the field is a Double. So we have a bunch of code similar to this that works fine prior to version 18:
public void foo(){
MyCustomObject__c obj = [select id, quantity__c from MyCustomObject__c limit 1];
foo(obj.quantity__c);
}
public void foo(Double d){
// do something
}
After changing to version 18, we get the error 'Method does not exist or incorrect signature: foo(Decimal) '. Apparently, v18 treats 'quantity' as a Decimal instead of a Double. So we have to cast our field to a Double as follows:
public void foo(){
MyCustomObject__c obj = [select id, quantity__c from MyCustomObject__c limit 1];
foo(Double.valueOf(obj.quantity__c));
}
1.) Is there any other solution for this? Is there any documentation on this?
2.) Will the Spring 10 IDE schema browser indicate the correct data types - Decimal vs. Double?
My question is, what is different between the IDE and the Migration Tool that would cause this error to occur? I am deploying the same folder using the same manifest (package.xml) file.
Trying to use the migration tool/Ant to deploy an unmanaged project. The first attempt failed and the error message read: LIMIT_EXCEEDED: Too many files in deploy call, limit is: 1500. So I changed the manifest file (package.xml) so it only included Apex Classes as follows:
I got the same error. I went to the 'src' folder (where the manifest files resides as well as the individual component subfolders i.e. 'classes', 'components', etc.) and deleted all of the folders except the 'classes' folder. This time it worked.
So it appears that the migration tool is trying to deploy all of the components in the folder regardless of what is in the manifest file. Is this a true statement or am I doing something wrong?
SUMMARY I have signed up for the Salesforce Partner Program and have created a managed app called ABC Company using my Partner Developer Edition account (dev org).
The app consists of one parent custom object (Project__c) and two child custom objects (Sent_item__c & Received_item__c).
I have a visualforce PDF page that displays the Project Summary with the Sent and Received related lists. For this VF PDF Page I have created an Apex Class that sorts/orders the list by Name ASC for Sent and Received Related Lists. I also have an apex test class with 100% code coverage.
The Generate Visualforce PDF Page works without any problems in my Partner Developer Edition account (dev org).
PROBLEM After successful installation of my app on my Enterprise/Platform Edition account (Test Org) as a managed app I receive the following error when I try to generate the VF page:
common.apex.runtime.impl.ExecutionException: SObject row was retrieved via SOQL without querying the requested field:ecpfinal__Project__c.Name
(The error only occurs in my managed solution when installed on another Enterprise/Platform Edition account (Test Org))
Can you provide the necessary code to fix this error? Do I need to add additional code to the apex class?

will a custom component controller 's constructor get called even if the "Rendered" expression evaluates to "false"? Below is a visual force page that has two components. Only one of them is rendered depending on the user's Profile name:
According to SFC documentation "values can be a primitive". An Integer is a primitive.
I am building a trigger that requires me to do a check on how many Circuits have already been defined. If the user is defining the first circuit, all fields are required. I had the count in a for loop and it works fine until I break the bulk trigger rules with Too many SOQL queries
Integer mycount = [select count() from Circuit__c where Device__c = :circ.Device__c];
So I thought I would put the count in a Map and correlate it to an Id.
Map<Id, Integer> circCountMap = new Map<Id, Integer>
([SELECT count() FROM Circuit__c WHERE Device__c in:devIds]);
But when I try to save, I get an error
Error: Compile Error: Invalid initial type Integer for MAP:Id,String at line 13 column 35
Why can't I do this? And does anybody have a suggestion for how I can get the counts so I can check each Circuit being inserted?
