[DHTMLXTree] Conflict when dynamically opening 2 or more nod

Discontinued products Uncategorized discussions
#1

I use tree.openAllItemsDynamic(nodeId) which seems to conflict with other tree.openItem(nodeId) when being executed in the same time. Is it normal? How come I usually (not always) get something like this



Javascript ErrorThe next error ocured :

‘that.G_node.id’ is null or not an object in localhost:8443/treecontroller?A … nContext=6 at line 294



whenever that happens?



Isn’t there a way to kind of lock the tree when nodes are being dyn loaded?



I tried to capture the onclick event, but it doesn’t look like it’s possible to prevent an opening by unfolding nodes with the mouse.





An input?







Thanks

Is it normal?

It is expected. Opening itself is not harmful, but any dyn. loading operation ( which can be triggered by opening ) will break openAllItemsDynamic chain and may cause mentioned error
You can lock whole tree on time of opening - can be done by

tree.attachEvent(“onXLE”,function(){
tree.lockTree(false);
});
…
tree.lockTree(true);
tree.openAllItemsDynamic(id);

( lockTree is a part of dhtmlxtree_li.js )

Isn’t the tree lock op part of the pro version?

Yes, it is part of pro version.
( technically it just renders transparent DIV over the tree’s area, so it can be easily reflected with custom HTML|javascript )

I was looking for a slightly subtler solution…

My tree has got to be locked for certain actions, but still respond for some non-critical requests; otherwise, what’s the point of ajaxyfing it?

The tree can load multiple branches at same time ( user can continue opening items, there is no need to wait while previous one loaded ) - the problem above related only to openAllItemsDynamic command.
