Steven,

 

I think you are right.  My point was more about breaking them into VOs first, rather then piping the whole query back direct.

Subject: RE: [flexcoders] Is it possible to return multiple recordsets to Flex from one Remote Object call

 

I'd take a very different view on this; if you have a business need to pass back a collection of data, that collection of data must have some "semantic" business meaning.  Perhaps it is "initialisation data" or "customer overview" or "customer portfolio" or "dashboard summary" or something similar. 

 

A "dashboard summary" might be a list of recent orders, a list of sales by territory and a summary of invoices owed.

 

So ... I'd create a business object - let's call it DashboardSummaryVO - and that would contain an array of OrderVO (recent orders), an array of TerritorySalesVO (sales by territory - probably a business object that by composition contains a further array of SalesVO objects) and an array of InvoiceVOs (for oustanding invoices).

 

I'd then return that DashboardSummaryVO from my service, which encapsulates in business/object terms, the data that is being returned to the client.  Furthermore, the code that picks apart the DashboardSummaryVO and updates your model/whatever will have infinitely more clarity for this object model.

 

Flex is the technology, but Object Oriented design is the paradigm (I hate people that use that word too), so be mindful of creating a well-defined object model.

 

Make sense ?

 

Steven

Darius,

 

I don’t know, passing back an uber array feels a bit monolithic (but maybe good for performance?).  Why not break them down into different Array’s of Value Objects.

 

For example:

 

EmployeeListVO – array of Employee VOs

InvoiceListVO – array of Invoice VOs

FooListVO – array of Foo VOs

 

Now you have the fine grained control of just asking for one or all of them.  And you can do what you want with each.  We represent our VOs as CFCs.  This allows you to type the package path in the returnType attribute of your CFCs.  Queries and Structures are not typed, you could get anything back and ColdFusion won’t report any problems.  How do you check for a well formed Struct or a well formed Query?  You might also want to look at the advantages of automatic object conversion into ActionScript.  You could have a 1:1 mapping between FooVO.cfc and FooVO.as.

 

Hope that helps,

Allen

Why not return an arrray containing recordsets and then setting the recordsets from the array as dataproviders to your controls by actionscript as follows:

 

resultArray looks like:

            [0] Recordset1 (an array of resultobjects from query 1)

            [1] Recordset2 (an array of resultobjects from query 2)

            [2] Recordset3 (an array of resultobjects from query 3)

            ….

 

And:

 myGrid.dataProvider = resultArray[0];

            myOtherGrid.dataProvider = resultArray[1];

            …

Subject: [flexcoders] Is it possible to return multiple recordsets to Flex from one Remote Object call

 

Hi,

My Flex app connects to a large ColdFusion application.  When I make
calls from Flex via RO to CF, I need to return more than one
recordset in order to populate my various datagrids.  I know how to
return one recordset as an Array of Structures, but what if I have 5
different querries that have 5 different recordsets.  How does one
deal with this?

Many thanks for any clarification one can give.

Darius
