In today's SalesLogix Web Developer class, we discussed an issue that someone in the class was having at runtime with a relationship that had a property that started with lower-case letters. Here are the details of that issue and the fix:

Scenario

Create a entity named "testProject" and then relate it to the Account entity. In the relationship, the Account will have a collection named "testProjects" (notice the property name starts lower case). You'll then use that relationship when you wire up your lookup on a form.

Problem

Every things builds fine, however at runtime you get an error saying "Could not find field '_TestProjects' in class Sage.SalesLogix.Entities.Account". Notice that the error refers to the property with an uppercase "T".

Solution

To fix this you just need to simply delete (or change) the relationship property to NOT start lower-case. Always name your relationship properties Proper-case, starting with an upper case letter always.

I don't know why this problem occurs. Seem that somewhere in the system an assumption is being made that the property name will be proper-cased (starting with an upper-case letter). However, I can tell you that you don't see the problem if you use the first letter upper-cased for the properties created in the relationship. Weird.
