    <p>I'm trying to use InfoVis SpaceTree to allow users to manage some information. Upon clicks on a node, a form is created and shown to the user, which allows him to update that specific node's properties, by ajax.</p> <p>Also, the tree is displayed using the "on demand" nodes pattern, so I have specific methods to retrieve any subtree with any depth for a specific node, using ajax and json data.</p> <p>My problem lies on the node information update after the user submits a node's form. For example, the node's name on the label should be updated after the user submits a name change to the node. Like this, there are (many) other properties that should be reflected on the label and the user is allowed to change.</p> <p>What I need is to update the internal representation of a single node after a form submit has been done, and redraw the tree. </p> <p><strong>Ideally</strong>, I wanted to "batch" update all the node's properties at once, using the same method I use for "on-demand" nodes, i.e., getting the newly updated node information by ajax: </p> <ol> <li>user updates node </li> <li>node is deleted from tree</li> <li>async request is made to get the updated node's information</li> <li>node is re-inserted on tree; tree is re-drawn</li> </ol> <p>I've tried to use <code>.graph.removeNode()</code> and <code>.graph.addNode()</code> functions, but this screws up the tree layout. The add and remove subtree facilities are not an option because then I would have to request a large amount of information and re-insert the whole subtree when only 1 node was updated.</p> <p>Is there any method or mechanism I can use to change the whole node's internal representation at once?</p>

    1. CO1: Why do you need to remove the node, when user updates the node ?

    2. COI don't. I just wanted to stress out that I wanted to completely update all of the node's properties, without having to go through each property one by one. This was important because there are some properties which are indirectly altered by consequence of the user's input. However, you are right: I should not need to remove the node. If I get the new json for the node, to update entire node at once, I should only need to update 2 vars: "name" and "data". Thanks!!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
