davecruso Querying against Attachment -- but outer query not working?
Hi all,
We're trying to generate a listing of attachments for a specific item (apprenticeship), but are having no luck with the outer query. The inner query (against Attachment) works. Any thoughts / suggestions? Thanks! Here's our code:
private List<Attachment> attachmentList;
public List<Attachment> getAttachments() {
PageReference pageRef = System.currentPageReference();
apprenticeshipID = pageRef.getParameters().get('id');
for (Lesson_Plan_Attachments__c u: [select id,Apprenticeship__c from Lesson_Plan_Attachments__c where Lesson_Plan_Attachments__c.Apprenticeship__c = :apprenticeshipID limit 1])
{
attachmentList = [select id from Attachment where parentid = :u.id ];
}
return attachmentList;
}
We're all getting errors like this:
ApprenticeshipFileExtension : Invalid conversion from runtime type SOBJECT:Apprenticeship__c to SOBJECT:Lesson_Plan_Attachments__c
... any insight into what's causing this, and how to rectify?
Anyone?? Even the inner query isn't working with this code:
public class ApprenticeshipFileExtension {
// RELATED RESOURCES
//
// relation to an object - http://community.salesforce.com/sforce/board/message?board.id=PerlDevelopment&message.id=4168
//
private final Lesson_Plan_Attachments__c ApprenticeshipRef;
public Attachment attachment {get;set;}
public string apprenticeshipID;
public string ctContactId;
public string urlstring;
public string url;
public string fileId;
ApexPages.StandardController stdController;
public ApprenticeshipFileExtension(ApexPages.StandardController stdController)
{
attachment = new Attachment();
this.ApprenticeshipRef = (Lesson_Plan_Attachments__c)stdController.getRecord();
this.stdController = stdController;
}
private List<Attachment> attachmentList;
public List<Attachment> getAttachments() {
// String apprenticeshipID = 'a0G40000003LVz0';
PageReference pageRef = System.currentPageReference();
apprenticeshipID = pageRef.getParameters().get('id');
for (Lesson_Plan_Attachments__c u : [select id,Apprenticeship__c from Lesson_Plan_Attachments__c where Lesson_Plan_Attachments__c.Apprenticeship__c = :apprenticeshipID limit 1])
{
attachmentList = [select id,name,lastmodifieddate from Attachment where parentid = :u.id ];
}
return attachmentList;
}
}
-- gives the same error message.
