Hi Lucas,

Thanks for the post, Its helpful.However I am just wondering if i can use the tree table to display checkboxes in place of output text.I want to use those checkboxes to recieve user inputs and save those somewhere.

Hi DS,
It will not work as is for JDeveloper 10.1.3.4 as it has ADF 10g rather than 11g. The database version is fine, 9iR2 or higher will do. For ADF 10g you should be able to do something very similar, as the TreeTable is also a component in ADF 10g. (the styling and the definition of the tree (data binding) rules is somewhat different in 10g).
Good luck! best regards

Lucas

Hi Lucas,

Thanks for your post. Its very very useful.

I have 1 quick q:
I work on Oracle Jdeveloper 10.1.3.4 and Oracle DB 10g. Would this example work as it is in the same or I need some change?

Thank yo Lucas for all your help.

Hi Lucas, thank you for the posting, it gave me hope of build something complex with the tables..
i tried your tutorial…but failed. I think the mistake related to the view link that i made, because i couldnt find TreeLevelMasterTotalingView accessor anywhere.
please provide the sample application so i can analyze it..or can i send my application to u?
and could u please elaborate more on the query suggestion from rob?

thanks

Thanks Rob, that is very useful. I should have taken a little longer tweaking the query. But now you did it for me. Great! Lucas
