Short System Data Type “IdentifierName” resulting in false Best Practice checks
If you have e.g. a form grid control name which is longer than 40 characters, the MorphX Best Practice check
fails with error like:
“Unknown data source <ControlName>”
The reason that the problem occurs is that the Best Practice check class that is generating this error
(SysBpCheckFormEditControl) uses variable of type “IdentifierName” to hold the name of the
datasource used on the control. The IdentifierName EDT is a 40 characters string but the datasource name
is several characters longer than this. Consequently, the datasource name from the control is truncated
so it does not match when compared against the actual datasource available on the form
(which are not being held in “IdentifieName” variable).
If you change the type of datasource from identifierName to unbounded str in
SysBPCheckFormEditControl.checkReference() method, this issue can be resolved.
Another option is adding the Best Practice error into AOT/Macros/SysBPCheckIgnore, the issue will be
resolved. E.g. add this line:
This is because that the errors are in the ignoreMap which is defined in SysBPCheck class. And the ignoreMap is
initialized according to the AOT/Macros/SysBPCheckIgnore Macro.
