Tracy, thanks for your reply. It looks like you are becoming my personam
trainer.
The way you described is moreless the way I set it up. But because I
could not get it working, I was thinking of using 2 AC's. It looked more
simple to me.
However, I will keep using only 1 AC, but unfortunately I need some help
again.
This is my code :
public function showRecord(pViewMode:String):void {
switch (pViewMode) {
case AVAILABLE_RECORDS :
this._records.filterFunction = getAvailableRecords;
this._records.refresh();
break;
case DELETED_RECORDS:
this._records.filterFunction = getDeletedRecords;
this._records.refresh();
break;
}
}
private function getAvailableRecords (obj:Object):Boolean {
return obj["flagForDeletion"].match('false');
}
I always get the error value is not a function on line return
obj["flagForDeletion"]
I also tried matching :
- false
- 'false'
- "false"
- 0
but no difference.
What I did before :
My field flagForDeletion in Flex is of type boolean, but the same field
is of type tinyInt in my mySQL-database.
When requestion the records from the DB, I convert the 0 or 1 to false /
true, before dropping them into the AC.
Hope my explanation is sufficient enough.
Thanks again
PS : Can you post a little piece of code how to combine 2 criteria in
one filterfunction?
