==============
I managed to produce a really confusing error in AX 2012. Look at the following piece of code:
MyExtendedDataType a
, b; a
= b;
Pretty boring, isn’t it? There is nothing to fail… except that I got a compilation error:
Operand types are not compatible with the operator. What?
Actually it become quite clear as soon as I simplified my code to this trivial example. There is clearly nothing wrong with my code, it must have something to do with the data type.
To make a long story short, I created a new extended data type of type enum and forgot to fill in the
EnumType property. Linking the EDT to an enum instantly solved the problem.
But beware – the compiler won’t detect many other uses of this incorrectly-defined type. For example,
MyExtendedDataType a = NoYes::Yes; is compilable X++ code even if
MyExtendedDataType has empty
EnumType.
