Vera long HREF's generated by Tapestry/Tacos-Tree
When using org.apache.tapestry.contrib.tree, the generated HTML contains extremely long
href's for the tree's nodes. The workbench examples run fine with reasonable href's.
The length of the href seems to double for every level of the tree, the example below
was taken from a direct child of the root node.
How are the parameters of such links generated? I was not able to change them by changing
TreeNode.hashCode or TreeDataModel.getParentUniqueKey.
Best regards,
Guido Wegener

RE: Vera long HREF's generated by Tapestry/Tacos-Tree
Posted by tsvetelin <ts...@rushmore-digital.com>.
Hi Guido,
I suppose that you are using the default implementation of ITreeDataModel.
When the TreeNodeView component generate node link it take the ID object of
current rendered node from ITreeDataModel. The default implementation return
a TreePath object as ID, this object contains pointers to the node and to
the parent id object(parent TreePath) and the sequence go to the root node.
So when the TreeNodeView serialize the ID for rendered node it serialize all
sequence of node to the root node. This is the reason why the link are long.
This is implemented in this way because in general case you can have only
one node with particular unique ID in parent node, but you can have another
node with same id in second parent node. For example - the file system, you
can have one folder/file with particular name in particular directory, but
you can have another file with the same name in second directory.
If you have some kind of ID field in your tree node data object, you should
make your implementation of ITreeDataModel. This is done in the file system
demo. There is a custom FileSystemDataModel and one of its methods that
return a object ID is:
/**
* @see
org.apache.tapestry.contrib.tree.model.ITreeDataModel#getUniqueKey(Object,
Object)
*/
public Object getUniqueKey(Object objTarget, Object objParentUniqueKey)
{
IFileSystemTreeNode objNode = (IFileSystemTreeNode) objTarget;
return objNode.getAbsolutePath();
}
In this case the sequence of TreePath is removed. There is only one String
ID for each file system node.
I hope this will be helpful.
