The actual bug seems to be related to selecting a non-draggable node(ie the root node, which is causing onBeforeDrag to return false.) Dragging the root node is going to cause bugs anyway.

I think...

There is a link to a live example in the post. The code in the first post is outdated, and was mostly a proof of concept anyway. All the updates were posted on the demo page.

There is no updates...

Sorry I haven't even looked at Ext4 extensions yet. I've only tried a few demos. So far I'm not impressed at all by their tree "improvements".

[by Deadmeat]

No it's very disappointing. Even worse it looks like I need to make changes to get it working again.

The bad news is that I'm not sure when I will get time to work on it. Since they're still...

[by Deadmeat]

Unfortunately not. The code is still available, and it's GPL so if anyone wants to pick it up and work on it, they're welcome to. If there are bugs (and I hear about them) I still try and fix them...

What sort of problems?

I'm not familiar with the updated tree grid example extension. It seems superficially similar to the old tree with columns example though. Dragging to the treegrid shouldn't...

Oops duplicate post

[by Deadmeat]

Short answer is no. Long answer is that you can work around it.

The reason it doesn't work is because of a gotcha with the way the multiselect tree does node selection. The default tree uses the...

I've posted an updated beta version for anyone interested.

You get it here: http://www.users.on.net/~clear/ext/index-beta.html

The selection change is nice. If you've ever hated how single...

Hi tritonBear,

Turns out it's a tree insertion order bug in the core version.

See bug and override fix here: http://www.extjs.com/forum/showthread.php?t=91506

Sorry I'm such a slacker and...

How odd.. where did my previous post go.

[by Deadmeat]

I've just updated the demo page to use ExtJS 3.2.0 so you can test it yourself.

See the extension thread here

It seems to work.

[by Deadmeat]

That makes sense. I imagined that it would be rare, and each instance evaluated on it's merits. I personally dread future maintenance for code I didn't author.

I'm willing to reorganize my code...

[by Deadmeat]

How odd. Looks like a bug in the 3.1.1 core. There is a demo here. One of the example tree is a vanilla tree (ie no multiselect) and shows the same issue.

This has fixed itself in ExtJS 3.2.0. I...

Is there a way to get a third party patch included as a default component in ExtJS. I don't mean a whole new class of widget, or just a small bugfix, but something in between, an upgrade to an...

[by Deadmeat]

This thread is a bit meandering, most of the issues raised are to do with offbeat problems, and bugs that area already fixed.

1) Is this maintained. That's hard to say. I'll say yes, but then I've...

[by Deadmeat]

You can use overrides (Ext.override) to replace code in the default components, instead of using an extension.

I have had some fixes included (allowContainerDrop and an ordering bug) but my...

[by Deadmeat]

This is probably the wrong place to ask. You should try one of the official ExtJS or feature request threads.

The Tree component virtually hasn't changed since the 2.x series (which this extension...

[by Deadmeat]

I honestly have no idea.

I can't think of anything in the MultiSelectTree code that would cause that. The loader code should be largely unchanged from the default tree. I'm not even sure where to...

I've done some more testing and...

You can delay the start of a drag longer by setting Ext.dd.DragDropMgr.clickTimeThresh to a bigger number. Currently its at 350ms (despite what the API docs say)...

I did a quick search/scan but couldn't find this...

The docs for Ext.dd.DragDropMgr incorrectly have the default clickTimeThresh as default 1000, instead of the actual value of 350.

I'm...

[by Deadmeat]

The flickering will be the cleanup of the drag proxy. Regardless of whether or not you move the mouse, it calls startdrag after about 350ms. This creates the proxy floating tree. It's actually hidden...

[by Deadmeat]

Okay I lied. It turns out I was just too lazy to spend a few hours working on it.

I was wondering what would be needed, and then reading the code, and then doing some tests, and well I hacked...

[by Deadmeat]

This is a sensible trade off. I must dig deeper and work out how the default gets around this problem. The transient instance is so hard to debug in Firebug though.



This annoyed me too, but...
