Display tobago selectable tree
Hi:
Is there a way you could able to display back what you have
saved in the database by indicate a checkmark on the Tobago tree? I
have set the selectable="multiLeafOnly". When user selected the leafs
that would like to save it in the database, then user retrieve back the
selected leafs and display with a check mark as indicated the leafs was
what he saved last time. Later user could de-selected the check box for
removing the existing leaf? Htanks.
<tc:tree value="#{Controller.Tree}"
state="#{Controller.selectedTrees}"
id="Tree" idReference="userObject.id"
nameReference="userObject.name" showIcons="true"
showJunctions="true"
showRootJunction="true" showRoot="true"
selectable="multiLeafOnly"
mutable="false">
</tc:tree>

Hi Volker:
I put it in action command or action method and it did pick up
the unchecked leafs. Thank you very much.

the getter of the TreeState is imho the wrong place to capture the
selection.
this should be done in the action method werd the result is stored.
the way you do this is ok, but you will get the selection before
rendering, not the one after submitting the page.

Hi Volker:
Where is a correct place to put? Because I am having trouble
when the GUI display it and I tried to unchecked one of the leafs (as
trying to delete the one that I don't want it anymore) and resaving what
was being checked on leafs. I was not able to pick up any selections at
all? Thanks.

Now, it display the checkbox on the tree that was being selected, but
when I unchecked one of the leafs or event try to resaving it. The
treestate never get never pick up the leafs that was being checked. Am
I doing something wrong? This is how I tried to capture? Thanks.
/**
* @return the _selectedCategories
*/
public TreeState getSelectedCategories() {
Set<DefaultMutableTreeNode> selection =
_selectedCategories
.getSelection();
boolean empty = selection.isEmpty();
if (!empty) {
_categoriesSelection.addAll(selection);
}
return _selectedCategories;
}

Hi,
just add all nodes which should displayed as selected to the selected
set in the treeState:
selectedTrees.getSelection().add(node);

Hi,
just add all nodes which should displayed as selected to the selected
set in the treeState:
selectedTrees.getSelection().add(node);
