data transfer from TreeField to the server module [message #1807262]

Hi,
In my application, on the form I used TreeField similarly, as it was in the example at https://scout.bsi-software.com/widgets/?dl=widget-treefield.
The content of this field comes from my class, extending AbstractCodeType.
This field is checkable.
I would like to submit data from this field to the server side service.
For this purpose, I am using an automatically generated transfer object containing the AbstractTreeFieldData type field.

My question:
How to read the elements selected by the user in the TreeField using this transfer object?

On the server side, I am able to read the tree structure using the AbstractTreeFieldData.getRoots () method, but I do not see the method to check which node was selected and its identifier/name. In addition, for all nodes of the TreeNodeData.getTexts () method and TreeNodeData.getValues () does not return anything.

You might want to consider the TreeBox widget instead: It is a ValueField, which means it keeps track of what the user entered/clicked.

The set of checked keys (equal to the key of your Code or LookupCall for the checked nodes) will be exported into the FormData and can be read or set on the server side of your application.

Thank you for the tips. It helped.

Although I preferred TreeField, because it had a nice option with nesting dedicated menu inside this field, but it is not a big loss for me, so TreeBox is also OK.
I added a menu outside this box and it does not look bad.
