Robert Bar created FLEX-33157:
---------------------------------
Summary: Sort class: _fields and fieldList variables can be out of
sync
Key: FLEX-33157
URL: https://issues.apache.org/jira/browse/FLEX-33157
Project: Apache Flex
Issue Type: Bug
Components: Spark: Sort and SortField
Affects Versions: Adobe Flex SDK 4.5 (Release)
Reporter: Robert Bar
Priority: Minor
Fix For: Adobe Flex SDK 4.5 (Release)
NOTE: the issue exists in both, mx and spark Sort classes.
Sort.findItem function is not able to configure search criteria and skips a
block of code due to outdated fieldList variable. It often happens when the
user sorts the AdvancedDataGrid by clicking on a certain column header. In the
shortest scenario you can reproduce it (without AdvancedDataGrid) as follows:
1. create Sort object and assign an empty array of SortField objects to it
-> _fields and fieldList are both empty
2. add SortField object directly to the array
-> _fields length is 1, BUT fieldList length is 0 (BUG) which disallows
findItem() operation to configure search criteria
