How to display(binding) values in the table from more than one node?

Question

Hi,
I have two nodes (TRIPS & AMOUNTS)in the context. How to bind these values into the table control?
When i bind second one, first one is getting replaced.

Hi Mog,
Of course it is possible to create a table from attributes of more than one node, and in some cases this is still necessary, but you have to do this the hard (manual) way.
If you have a table control, have a look at the properties and the elements belonging to it.
First of all, there is the property "dataSource", which binds to a multiple node (let's name it TableRootNode). This means that for each element of THIS node, one row is created. In each row the data of exactly one element of this TableRootNode is displayed.
Then you have columns in this table. Inside of the columns there is a header and an editor. The editor is the interesting part.
Normally the primary property of this editor is bound to an attribute of the TableRootNode. Then everything works as expected. If it binds to an attribute of a subnode (SUB) of TableRootNode, then in row i the data of the subnode of the i-th element of TableRootNode is displayed. There is no need for SUB to be a multiple node, but it must not be a singleton.
If you bind a property of the editor to an attribute, which does not lie in the subtree of TableRootNode, then you will see the same value in each row.
Now it depends on the structure of your context. Take the node, which is relevant for the change in each row (I assume it is TRIPS) and bind the table to the node as you are used to. Then for each additional column, you have to create a new column in the tree, create a new header element with a title and a new editor (e.g. textview or inputfield) and then bind the right property of the editor to the corresponding attribute in node AMOUNTS).
If these 2 nodes do not have parent-child-relationship, the tip to create a new node, which consists of the attributes of both nodes is the only solution.
