On occasion I come across platform behaviour that simply doesn’t make sense. A recent case in point being a v25.0 VF bug where bottom buttons in a pageBlock component ignore the edit and show button directives related to inline editing. In such cases I find it useful to check the Known Issues List in addition […]
An interesting addition to the Summer ’12 release is the pilot of separate OWD settings on custom objects for external users. For example, a custom object may have public read-write sharing for internal users and private sharing for external users. In many cases this will simplify the sharing model significantly as the rules below have […]
This post is the second in a series exploring record access considerations with the different portal user license types. This post covers the Customer Portal Enterprise Admin type. By way of reminder, the decision tree below should be used when making the high-level decision on the appropriate license type for the different user populations within […]

When designing portal solutions on the Force.com platform it is imperative to understand the sharing model implications of the user licenses and related base user profiles in play. In this post I’ll outline the key considerations in respect to record access for high-volume portal user license types; Authenticated Sites (aka Platform Portal) and Service Cloud […]
In certain cases it may be desirable to have some users authenticate in the standard Salesforce manner, whilst another user population authenticates via single sign-on (SSO). This mixed authentication scheme scenario may result from rollouts to new departments etc. What are the considerations? The first concern is whether Delegated or Federated Authentication will be used […]
The Summer ’12 release introduces some fundamental changes to the functionality of lookup relationships. In summary: 1. Optionality. Lookup relationships can now be set as mandatory (Required Attribute). This is great news in that the usual validation rule enforcement can now be forgotten. 2. Referential integrity. Prior to Summer ’12, the parent record could be […]
There may be cases where a pessimistic locking strategy makes sense within your custom Apex script, for example the available inventory statistic on a Stock record may need to be locked while your code works out the correct value to decrement. The interesting, but rarely used SOQL keyword “FOR UPDATE” can be applied to SOQL […]
For experienced developers, the lack of reflection capabilities in the Apex language can be a limitation in the type of patterns that can be ported from other languages (Java, C# etc.). With Summer 12, the Type class now supports the newInstance method, enabling instantiation via the class name as a string. Sounds simple, but this […]
As of the Summer ’12 release FieldSets can be accessed through Dynamic Apex (or Apex Describe). Remember, FieldSets are admin configured arbitrary groupings of fields, added on the object detail page within setup. With the upcoming release, controller code can now dynamically build a soql query that retrieves the data for the fields in the […]
