Environment

Product: OpenEdge Version: 11.5 OS: Windows Other: Progress Developer Studio for OpenEdge

Question/Problem Description

Organize USING Statements inserts unused USING statement.
This happens when a variable that matches a class name is passed as input parameter to a procedure/method/function call, and if the invocation does not qualify the parameter with the INPUT keyword.

Steps to Reproduce

Clarifying Information

Following code shows the issue, as long as a class type "ReferenceNode" is present somewhere in the project.

/*
 Make sure Infragistics4.Shared.* assembly is in assemblies.xml.
 That assembly holds Infragistics.Win.CalcEngine.ReferenceNode class type.
*/  
DEFINE VARIABLE ReferenceNode AS INTEGER NO-UNDO.

FUNCTION dummy RETURNS INTEGER (INPUT somevalue AS INTEGER):
END FUNCTION.

PROCEDURE donothing:
    DEFINE INPUT PARAMETER dummy AS INTEGER.
END PROCEDURE.

/* these trigger inserting of "USING Infragistics.Win.CalcEngine.ReferenceNode FROM ASSEMBLY." */
dummy (ReferenceNode).
RUN donothing(ReferenceNode).

Error Message

Defect Number

Defect PSC00330210

Enhancement Number

Cause

The exact cause is not known at this time.

Resolution

Until the fix is available, use the workaround below.

Workaround

Ensure that in the code, INPUT parameters are explicitly labelled as such. To continue above example:

/* these statements avoids the issue. */
dummy (INPUT ReferenceNode).
RUN donothing(INPUT ReferenceNode).
