Why are memory errors hard to debug?

Answer

The first thing to understand about memory errors is why they're different from other bugs. I claim the main reason they are harder to debug is that they are fragile. By fragile, I mean the bug will often only show up under certain conditions, and that attempts to isolate the bug by changing the program or its input often mask its effects. Since the programmer is then forced to find the needle in the haystack, and cannot use techniques to cut down on the size of the haystack, locating the cause of the problem is very difficult.
Consequently, the first priority when tracking down suspected memory errors is to make the bug more robust. There is a bug in your code, but you need to do something so that the bug's effects cannot be masked by other actions of the program.

Question { 2269 }

WHEN SHOULD I BE USING A COMPONENT INTERFACE?

Answer

If you need to insert/update/delete data through PeopleCode, and your PeopleCode will require replicating a lot of existing business logic that already exists in a component then a component interface is the best approach. Once you learn how to use them, they will be the fastest and most robust solution for such cases. If you are performing simple changes, then using a CI becomes overkill as there is an overhead to using a CI on both the system and on development time. Similarly, large amounts of batch processing may be too much for a CI to handle or may be considerably slower using a CI.

Question { 2157 }

When I create my component interface, why can't I see any Getkeys?

Answer

The search record for your component does not have any search keys defined. Go back and define search keys as these are used as Getkeys.

Question { 2148 }

Why are my Findkeys missing certain fields?

Answer

Findkeys are derived from search and alternate search keys on the component search record. If you have a key but it is neither a search key nor alternate search key, then it will not be available as a Findkey.

Question { 3248 }

When I test my component interface, why do I get a "Not Authorized" error?

Answer

Check that your component interface is included in a permission list that you have access to. Also check that you have access to all possible methods (Get, Save, Create, Cancel, Find). If you delete a component interface through application designer, it is also removed from any associated permission lists so this may be another reason why your new component interface (with the same name) is not authorized any more.
Also, make sure you are not trying to do something in your code that the CI can't do. For example, if your CI doesn't have a create method, you can't set security for it, so you will get a not authorized error if you have code that attempts to perform a create. This is because the authorization error is usually the first error to be displayed.

Question { 2193 }

Why does my component interface not have a Create method?

Answer

Create is only available if the underlying component allows Add mode. If it doesn't then you can't create anything in the component, and thus you can't create anything using the component interface. The create method will be disabled in the component interface properties.
