So, the upshot is that Flex will try to evaluate filterData.true or filterData.false. I'm pretty sure that won't work. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "fatmanchan2009" <fatmanchan2...@...> wrote: > > Hello > > Can anyone figure out this problem im currently having, and explain the reasons and cause of this proplem. > > I have an XML file of track data with a bunch of attributes > > <track> > <item uniqueTrackId="1000000" albumId="12" trackId="1" genreId="13" artistId="6584"> > ... > </track> > > i use this code to execute the filtering on the data, the name is artistId and the value is 6584, so the data should come back with all the artists with artistId 6584. > > var filterData : XMLList = _trackData.item; > > for each (var prop : Object in _propertiesList) > { > filterData = filterData.(attribute(prop.name) == prop.value); > } > > but i keep getting this exception, when its applyin the filter, so within the for loop > > TypeError: Error #1006: value is not a function. > > So anyone that can figure what the problem is, would be a big help Thank You > > > Stephen Chan >
