AFTER INSERT and AFTER UPDATE triggers on same table

 Hello,

I have a table "T" and 2 triggers on that table: TR1 and TR2. TR1 is an after insert trigger and TR2 is an after update trigger. The problem is that when TR1 executes an update on column "x" of table "T" TR2 is not fired. Could somebody give me any clues why this is happening and some possible solution?

Thanks in advance.
