Lotus Notes $$Return.

I may have this wrong, but based on the @IF funtion from the help, you may not be able to do this the way it is presently set up

The @If statement has an odd number of parameters with a minimum of three, as follows:
The condition is the first parameter and every other parameter thereafter if the @If statement has multiple conditions.
The statement that is executed if the condition is True is the second parameter and every other parameter thereafter if the @If statement has multiple conditions.
The statement that is executed if the condition is False is the last parameter.
The simplest @If statement has the following syntax:
@If(condition; True statement; False statement)
An @If statement with three conditions has the following syntax:
@If(condition1; True1; condition2; True2; condition3; True3; False)
The @If function is evaluated left to right, and the first condition that is True causes its corresponding True statement (that is, the next parameter) to be processed. No further evaluation or processing within the @If statement takes place. If none of the conditions are True, the False statement (that is, the last parameter) is processed.
The True and False statements take various forms, depending on their context:
If the @If statement is the last statement in a formula that evaluates to a result, the True and False statements must evaluate to a result.
If the @If statement is the righthand side of an assignment, the True and False statements must evaluate to a value suitable to assignment to the field or temporary variable on the left side.
Otherwise, the True and False statements must cause an action.
A True or False statement in @If cannot contain an assignment. The left side of an assignment can occur only at the beginning of an outermost statement in a formula. The following syntax is illegal:
@If(condition; variable := value1; variable := value2)
You must write it as:
variable := @If(condition; value1; value2)

Scenario:
A Page from systemA(we refer it as PageA) calls Notes Web Form (refer it as WebForm) and submits and then run $$Return.
Inside $$Return, it eithers return Msg page or OKMsg page back to PageA.

When PageA calls WebForm, it passes 2 variables "Deal_id, standalong_flag as 1234, N" to WebForm.

Questions: we expect to receive OKMsg page it does. However, the variable for our tracking is odd. This is what i dont understand.

=======================================

The following is the code of $$Return in a Web form.


FIELD Deal_id := Deal_id; // a pass in from Query_String come another page.
FIELD StandAlone_Flag := StandAlone_Flag; // always pass in with value as "N"

// it is a computed field with formula @If(@IsNewDoc;@If(@Trim(Deal_id) = "";"Y";"N");StandAlone_Flag_1)
FIELD StandAlone_Flag_1:= StandAlone_Flag_1;

FIELD myValue := myValue;

// For OKMsg, assuming OkPagelink is some http: .... set somewhere and will display the Deal_id+StandAlone_Flag+StandAlong_Flag_1
OkMsg := OkPagelink;      

// For Msg, assuming existingdoclink is some http: .... set somewhere and will display the Deal_id+StandAlone_Flag+StandAlong_Flag_1
Msg :=  existingdoclink;    // assuming existingdoclink is some http:// .... set somewhere.

@Setfield(myValue, Deal_id+StandAlone_Flag+StandAlong_Flag_1);

@If(@Trim(Deal_id) = "" | @Trim(StandAlone_Flag) != "N"| @Trim(StandAlone_Flag_1) != "N";
          @Do(   @SetField("myfield", "Msg"); Msg )  ;
          @Do(   @SetField("myfiled", "OKMsg");   OkMsg)

==============================================

Now when we calls the Web Form from some other page passing in the Deal_id and the standalone_flag as N.

We submit the form where it triggers the $$Return.

The result i got is:

The variable saved in the Web Form document is
myValue = 1234NY
myfield=Msg

However, what we get back from PageA is OKMsg and 1234NN.

Wondering, $$Return would run twice?
Before the Web form doc saved, it runs @setfield etc in notes client side.
And runs again in PageA, and returns OKMsg.

Please explain why it have myfield saved as Msg but gets OKMsg in PageA.


Something i dont understand fully how $$Returns get each statements run at the timing.

Move your code to the WebQuerySave event, not in $$Return.  You can just put @Formula's in there directly, it needn't be an agent.
Then you may still use $$Return to return the correct page or html message (like marilyn says)
