I'm working on a retail site which displays a list of search results in a DataGrid. I'm using the "expando" feature to show details for these items when the user "expands" the row, similar to the example here:

Hi,
I'm using a dijit Tree widget hooked into a read-only data store, based on the one given here:

Hi,

I post this question here although I'm not using dijit. I hope either it can also be answered or moved to the correct place.

I have a Tree and a RPCController to load the nodes via a servlet. If I expand a node the data is loaded from the server and displayed correctly.

Now I want to search for nodes in the tree and then expand the nodes I found. The search is done on server side and I get back the path from the root to the corresponding node.

I can programmatically add a new item, with children, to a tree without problems. However, the moment I click the plus sign to expand the first node and see the children I get this exception:

dojo.data.ItemFileReadStore: Invalid item argument

Here's the JSON of the Tree Store data:

I've also tried having a key on the child entry, but it's had no effect.
