Creating DataSetFilter in Actionscript

[GoogleCodeExporter]

Hi, 

This is a very useful library.

However when trying to dynamically create filters in actionscript I have run 
into some problems. 
It seems you have to call the addDataFilter function before you set the 
filterValues on a 
DataFilterParameters object. Otherwise, the filter does not work.

for e.g.

this works:
var filter : DataFilterParameters = new DataFilterParameters();
dataFilterSet.addDataFilter( filter );
filter.filterValues = [false];

this does not:
var filter : DataFilterParameters = new DataFilterParameters();
filter.filterValues = [false];
dataFilterSet.addDataFilter( filter );

It would also be good if there was an actual actionscript example to follow. 

Thanks.

I'm gonna try to write a AS example for the DataFilterLib and post it here.
Sorry for the delay, i thought i would get an email when someone raise an issue 
but
well, i didn't

Hi,
here is the blog post on how to use the DataFilterLib only using ActionScript:
http://www.flex-tutorial.fr/2010/06/01/datafilterlib-using-the-datafilterlib-wit
h-actionscript-code-only/
It's on a french blog but it's written in english, don't worry :).
I can write some more AS examples but if you have understood this one, i think 
you
should be able to reproduce any other example with no problem.
If you need some more AS examples or some help on your project, i'll be glad to 
help.
Just send me an email at fnicollet (AT) gmail (.) com

Cheers,
Fabien

In reading the very first post, I too had the exact same issue.  I read your 
post about how to use it in actionscript that the primary difference is that 
you are setting the filterValue via a UI component where the original poster 
and I want to set it to a value while creating the parameters.  

I made the following change to the DataFilterSingleValue.as constructor and it 
worked the way as the original poster would like:

    public function DataFilterSingleValue(parameters:DataFilterParameters) {
      super(parameters);
      // change starts here
      if( parameters != null ) {
          _values = parameters.filterValues;
      }
      // change ends here
    }

Would you consider making this change part of the code base?
