TreeNode isLeaf with RestDataSource

[jakob]

Hello,

i want to display a tree in a TreeGrid that is usind a RestDataSource returning XML Data.

It is working fine, but the problem is, that every node can be expanded regardless if it is a childrennode or not. If I click on a node that has no children, the root item become closed.
TreeNode has a method
http://www.smartclient.com/smartgwt/...Folder(boolean)
or Tree has
http://www.smartclient.com/smartgwt/....tree.TreeNode)
I can not use this method, because of the RestDataSource.
Can I set properties in the XMLanswer to determine whether this node has children or not which means is it expandable or not.
For now I set only the fields that i have defined in the datasource.

BestRegards
Jakob

Yes, the default value of the isFolderProperty is "isFolder", so just add nodes that say isFolder:"false" where you don't want folders.

To further clarify, the XML returned to the RestDataSource can include the following:

<record>
<isFolder>false</isFolder>
...
</record>

to indicate that record is a "leaf" node and doesn't have children.

that works!
Does that mean that I can set every property for which a getter or setter on a tree or record exist in that way?

Thank you :)

Yes, DataSource fields correspond to ListGridRecord / TreeNode properties.
