Autodesk Forge setNodeOff turns all nodes off - autodesk-forge

Question

When I pass an array of dbIds to be turned off the viewer is turning every node off in my model.
Autodesk.Viewing.Viewer3D.prototype.turnOff = function(dbIds) {
var node;
$(dbIds)
.each(function(index, item) {
node = viewer.model.getData().instanceTree.nodeAccess.nodes[item];
viewer.impl.visibilityManager.setNodeOff(node, true);
});
}

If you pass the id of a parent, it will turn off all its children, which is probably what happens in your case. Turning nodes off definitely works fine, you can take a look at my demo at https://forge-rcdb.autodesk.io.
Select a row in the database view or a segment in the pie chart:
What you need to do is to get the leaf node ids, only leaf nodes are represented by geometry in the viewer.
Here is some ES6 code sample, extracted from there:
static getLeafNodes (model, dbIds) {
return new Promise((resolve, reject)=>{
try {
const instanceTree = model.getData().instanceTree
dbIds = dbIds || instanceTree.getRootId()
const dbIdArray = Array.isArray(dbIds) ? dbIds : [dbIds]
let leafIds = []
const getLeafNodesRec = (id) => {
var childCount = 0;
instanceTree.enumNodeChildren(id, (childId) => {
getLeafNodesRec(childId)
++childCount
})
if (childCount == 0) {
leafIds.push(id)
}
}
for (var i = 0; i < dbIdArray.length; ++i) {
getLeafNodesRec(dbIdArray[i])
}
return resolve(leafIds)
} catch(ex){
return reject(ex)
}
})
}
static async isolateFull (viewer, dbIds = [], model = null) {
try {
model = model || viewer.activeModel || viewer.model
viewer.isolate(dbIds)
const targetIds = Array.isArray(dbIds) ? dbIds : [dbIds]
const targetLeafIds = await ViewerToolkit.getLeafNodes(
model, targetIds)
const leafIds = await ViewerToolkit.getLeafNodes (model)
const leafTasks = leafIds.map((dbId) => {
return new Promise((resolveLeaf) => {
const show = !targetLeafIds.length ||
targetLeafIds.indexOf(dbId) > -1
viewer.impl.visibilityManager.setNodeOff(
dbId, !show)
resolveLeaf()
})
})
return Promise.all(leafTasks)
} catch (ex) {
return Promise.reject(ex)
}
}
