Kirk:
The code below is used to populate dynamic variables with data coming in
from SAP via XML:
*C_LONGINT*($index_L)
*For *($index_L;1;*OT_SizeOfArray *
($orderListHandle_L;"$orderDetailObjectNames_AT"))
* C_TEXT*($objectName_T)
$objectName_T:=*OT_GetArrayText *
($orderListHandle_L;"$orderDetailObjectNames_AT";$index_L)
*C_TEXT*($tag_T)
$tag_T:=*OT_GetArrayText *
($orderListHandle_L;"$orderObjectTagNames_AT";$index_L)
(*OBJ_GPBN *($objectName_T))->:=*OB Get*($orderHeaderDetail_O;$tag_T;
*Type*(*OBJ_GPBN *($objectName_T)->))
*End for *
The OT_ methods are wrapper routines for Object Tools and OBJ_GPBN is a
wrapper for Object get pointer(Object named).
When working with OB commands or OT commands, I use wrapper routines where
possible but, in this case, I'm using the 4D command because I want to use
a very, very nice feature that 4D included in OB Get - the Type parameter.
When creating a variable on a form, dynamic or otherwise, the Type is
important because it allows us to assign a filter/format. The Type
parameter of OB Get plays right into that.
While this isn't using Process tags, "it's the same (but different)" in
that it's a way to parse incoming JSON into variables.
After the first version of this code was released, we decided to add
another value coming back from SAP. All I had to do was create a dynamic
variable with a name that matched the name coming in from SAP XML payload,
select the variable and set the Type value in the property list, and assign
a format to the dynamic variable. Next time I got data back from SAP, the
tag in the JSON matched the name of the object on the form and the variable
was populated. No code change. No bugs. *Very* bueno.
BTW, we are using code from the 4D tech note component that converts XML to
JSON - many thanks to Timothy Tse for the tech note.
