How to use a value in a field

Question

Hi!
I made a tree that shows data from 2 tables.
When i pick one of the items in this tree, The tree gives me the ID and put it in a text field.
Now, I want an event that gives me some values using this ID and later fill some text fields in the same page.
In few words, i want an event after i receive the ID in a text field to get more data and field some text fields with these data.

Thomas,
By the time the value appears in a field -- an "item" in HTML DB terms-- you can reference it using bind variable syntax. To populate other items based on this key value, you could use a Before Header process such as:
select ename, sal
into :P1_ENAME, :P1_SAL
where empno = :P1_EMPNO
Assuming you have items on your page called P1_ENAME and P1_SAL, respectively. Furthermore assuming that the text field (item) that the ID was put in is called P1_EMPNO.
So, you don't really need to create an event. In this case, the event is the loading of the page, which will trigger your process before its header is rendered. The process will populate form fields (by populating session state) based on a session state value set by you clicking on a tree link.
