Suite of my last message
Hi all
I've Found the bug concerning the GetChildren method the story is :
I use a version of PostgresRDBMSAdapter (which extends
StrandardRDBMSAdapter) which doesn't redefine the
clearBinding(Connection connection, Uri uri, Set UpdatedBindings)so the
Set of updatedBindings is ignored (see StrandardRDBMSAdapter) to avoid a
complete clear instaed of a "smart" clear (just the updated
bindings)I've written this method using the MySQL example and joined to
this mail the result source This works in my project.
Enjoy !(in fact I'm sure you gonna push it in your favorite trash as
usually)
Regards

Digging in the slide's code I have troubles with the
StrandardRDBMSAdapter class
The method storeObject use the bindings attribute to fill the Binding
table it seems OK
The method retrieveObject use binding table to fill the children
attribute This explain why getChildren returns nothing
Is it a bugg ? does anybody can explain me how this class works? The
source code of this class is so well commented ! 2 lines of comments
composed with three words each

Hi all
I have a trouble using structure.getChildren(token,parentNode) : this
method return an enumeration with 0 elements, but, when I build the
structure I use the
node.addChild method to set up children. To check it, I use a Postgres
JCDBA : I list the parent_binding table evrythig is correct and I
can see parents and children links in the tree structure.
Is there any known bugs or patch concerning the getChildren method ?
From an other hand , I get spam messages with links to pornographics
sites :
