Hi,
I need to iterate through the HtmlTree and / or the TreeModelBase to get
the expanded nodes and the selections of the nested
selectBooleanCheckboxes.
Could someone be so kind and give me some pointers?
- how to get each item/node address
- how to get the selection status of the selectBooleanCheckboxes
Right now the expanded nodes stays fine between requests, but then the
checkbox selections get lost.
I need this to re-create the tree between sessions, so the extracted
informations will saved persistent and applied again.
Thank you in advance,
Andreas
