Hi, 

I'm using the DLRS tool and need to change the direction that concatenated data is being order by. 
I'm doing this off of a custom Date field and have tried
Date__c DESC
but this throws up an error that my field does not exist.

I'm not sure if I am using DESC correctly within the tool? 

Thanks,

Natalie

Hi,

I have a list button on a related list called Resource Allocation against my Opportunity object. I have created a mass create record visualforce page that is related to the button. I am pulling my Master Detail Relationship onto my Table, and want to pre-populate it with the Current Record ID of the Opportunity record I selected my button from.

Piecing together elements I found online I was able to create an extension to get the Opp ID, however when I use the button I recieve the following error.
Invalid conversion from runtime type Resource_Allocation__c to Opportunity 
Not sure how I recieve this as there was no error when saving the apex class or visualforce page. I may have just written jibberish as I am new to Apex.

Any Help would be appreciated on this!

Hi,

A developer created a piece of apex code back in 2015 that is blocking a current deployment. For some reason it has only just started to fail, and without knowing the reason why, I (a non-developer) need to address the errors within the class.

The Apex class keeps updates of a portal user in sync with its corresponding contact. As far as I can see, as part of the Test, the code is creating a new portal user and contact record based on the Current Users details.

Unfortunately due to a flow triggered by contact creation, the class and subsequent trigger are not firing.The flow is looking for the account record of the contact that is being created, to update fields within the contact record. 

Is their a way to capture within the apex class the current user's related contact detail, to pull the account record to satisfy the flow? 

Hi, 

I'm using the DLRS tool and need to change the direction that concatenated data is being order by. 
I'm doing this off of a custom Date field and have tried
Date__c DESC
but this throws up an error that my field does not exist.

I'm not sure if I am using DESC correctly within the tool? 

Thanks,

Natalie
