Trevor North created FLEX-33172:
-----------------------------------
Summary: HierarchicalCollectionView only accepts sort fields of
type mx.collections.SortField instead of any ISortField implementation
Key: FLEX-33172
URL: https://issues.apache.org/jira/browse/FLEX-33172
Project: Apache Flex
Issue Type: Bug
Components: Advanced Data Grid
Affects Versions: Apache Flex 4.8 (parity release)
Reporter: Trevor North
Priority: Minor
I have written an extension of HierarchicalCollectionView which implements the
IList interface such that I can make use of hierarchical data in the various
Spark data controls (primarily to allow implementation of a spark tree data
grid).
HierarchicalCollectionView accepts a sort property of type ISort and is
supplied an instance of spark.collections.sort by my data grid. This is all
fine, except that it's sortCanBeApplied function explicitly expects sort fields
of type mx.collections.SortField where in this case I actually have instances
of spark.collections.SortField.
The fix for this is trivial in that sortCanBeApplied should in fact be
expecting sort fields of type ISortField.
ie. var sf:SortField = sort.fields[i]; should read var sf:ISortField =
sort.fields[i];
I've kludged around this by converting all the sort fields to
mx.collections.SortField in my class, but it's a long way from pleasant and I'd
appreciate it being fixed properly!
