Re: [flexcoders] getting the sum of values in list datafield.

2014-08-29 Thread Scott Fanetti [email protected] [flexcoders] 
IMHO - you should create a separate bindable string and set the value to that 
instead of directly setting the .text property of a text field.  Your reduce 
function seems ok - just run each object through the filter function to see if 
it returns true. Only objects that return true should be added to the sum. 

You are 99% of the way there.  What is tripping you up?

Re: [flexcoders] getting the sum of values in list datafield.

2014-08-29 Thread Alex Harui [email protected] [flexcoders] 
The code looks mostly ok.  I noticed you commented out the addEventListener 
calls for COLLECTION_CHANGE.  I'll bet it threw an error becuae expenseAr is 
null until the RemoteObject returns a result.  I would move the 
addEventLIstener call to expenseResult() method when you know expenseAr is 
valid.

Subject: [flexcoders] getting the sum of values in list datafield.



Hello, i have a flex list that is populated by an arraycollection. in the 
arraycollection i have a field subTotal and i would like to calculate the 
subtotals from that field and pin them to a text component and i would like to 
do that even when the list is filtered. below is my code

layout="vertical"
width="100%"
height="100%"
verticalAlign="top"
verticalGap="0"
&n! bsp;   paddingTop="0"
paddingBottom="0"
paddingLeft="0"
paddingRight="0"
xmlns:ns1="ascript.*"
