Tree getPath returns path of ids, not names

[pboysen]

I load a treegrid from a RestDataSource shown below. If I request a getPath(node) I get a path like /1/4/7 rather than /lib/foo/bar. If I try to get the NameProperty, it display "$399". If I try to set the name property I get a null exception. Since a Datasource creates the tree, how do I set it up to display names in paths?

private ProjectDataSource getData(Map<String,String> args) {
String context = args.get("context");
assert(context != null);
ProjectDataSource datasource = new ProjectDataSource(context,"ThinkSpace","library.xq");
datasource.setRecordXPath("/response/data/record");
for (String name: args.keySet())
	datasource.addParameter(name,args.get(name));
 DataSourceIntegerField id = new DataSourceIntegerField("fid", "ID");
id.setValueXPath("@fid");
id.setPrimaryKey(true);
id.setRequired(true);
DataSourceIntegerField parent = new DataSourceIntegerField("parent", "Parent");
parent.setValueXPath("@parent");
parent.setRequired(true);
parent.setForeignKey("fid");
parent.setRootValue("1");
DataSourceBooleanField isFolder = new DataSourceBooleanField("isFolder", "IsFolder");
DataSourceTextField name = new DataSourceTextField("name", "Name");
name.setValueXPath("@name");
name.setRequired(true);
DataSourceDateField modified = new DataSourceDateField("modified", "Modified");
DataSourceIntegerField size = new DataSourceIntegerField("size", "Size");
DataSourceTextField icon = new DataSourceTextField("icon", "Icon");
datasource.setFields(new DataSourceField[]{id,parent,name,isFolder,modified,icon,size});
return datasource;
	}

Hi Pboysen,

How are you trying to set the nameProperty such that you get an exception?

Does the field you are trying to use as the nameProperty have unique values on a per-sibling set basis?

[pboysen]

sibling names are unique

Yes, this is a tree of filenames so the names are unique within a folder.
Actually, the default property is "name" so I shouldn't have to set anything.

treeGrid.getData().setNameProperty("name"); gives

I had the same problem. I think you shoul set Name property once data has arrived, hence, tree has been created. i.e.

                grdModules.addDataArrivedHandler(new DataArrivedHandler() {
			
			@Override
			public void onDataArrived(DataArrivedEvent event) {
				grdModules.getData().setNameProperty("title");
			}
		});

although, docs say the default is "name", that didn't worked for me. You should explicitly set that property even if your data has a "name" property. Another thing is that Tree.getPath(TreeNode) returned me the path with a prefix "0_0/". I've just get rid of it with a replace.

Cheers!
