I can think of several instances where having a root node would be great as well as several instances where it wouldn't be. A good implementation of tree would not require a root node. Keep the root node, but give them an option to not display the root node, thus giving the same affect. The root node would be always expanded, just make sure the +/- icon looks correct.

If there is no "label" in the constructor just assume that I didn't want a root node (this was the default behaviour in .9, why break it?). It is nice to have, but also nice to hide.

Thanks.

I also need a rootless tree, or at least one where the root is specified by the top level item from the datastore. I have a case where I have hierarchical data that I want to display as a tree. This comes from the datastore and I want the root node to be a particular top level item from the datastore. The tree widget puts a root node above that one, so it looks wrong. I agree there needs to be a configuration attribute on the tree that controls wether a root node is displayed or not. Maybe the attribute could identify which item from the datastore is the root node. This might also help with the issue of all reference items that are top level items also being rendered as top level tree nodes when they are actually children of the root level item. So they appear twice in the tree, once as children of the real root node item and again because they are top level datastore items.

If the data store is single rooted, have a singly rooted widget. Otherwise have a multiply rooted widget. IMHO, having the widget mirror the datastore makes it easier to configure and makes it easier to handle events on the root node without special case code.

I do not generally find singly rooted trees to be particularly useful since they add a superfluous click to the user's workflow.

I was looking at the new code and noticed that the only event the tree was publishing was "execute". The events "afterTreeCreate" and "beforeTreeDestroy" are pretty handy. Are they going to be supported?

BTW, I agree, trust the data store. If the data store is single rooted, have a singly rooted widget. It will be easier to configure and manage events.

Great to hear that the tree is coming along. Any examples of drag&drop ?

The Treasury said the cheapest viagra price online cost would be met in part by underspend from the BBC's promotion of Digital TV switchover.

Since the United States, buy viagra now online European Union, Japan, Canada, and a handful cheap generic cialis online of other countries announced their participation in the cialis mail order online Anti-Counterfeiting Trade Agreement negotiations in October 2007, the ACTA has been dogged by controversy over the near-total lack of transparency.

Secondly, a lot of observers cheapest Cialis price believe that the new president is too ambitious, and should concentrate his/her/its energies on only a number limited of key policies.
Success depends well as the mail order generic cialis capacity of Obama to direct his/her/its agenda, as it makes for every president determined generic sildenafil citrate online to make more that increasing change", said William Galston to Brookings Institution scientist.
But his/her/its biggest problem buy cialis without a prescription can be the reluctance of the public American to have confidence in government to solve their problems.
The electorate American, in spite buy vardenafil no prescription of the crunch of the credit, appears to fear the big government again more of Buy Viagra in London big business, according to recent elections.
Nearly half (48%) would have buy generic levitra online less services and smaller government rather, with 40% to want the biggest government, the most belated Bench election found.
"The public mood was always be buy generic propecia online skeptical about big government", said Andrew Kohut, director of the Center of the Research of the Bench.
M. that Obama appears to want to buy cheap Doxycycline online forge a new paradigm between citizens and government to which the government takes part like enabler and guarantor of key services as health and education.
For his/her/its critiques on the Buy Viagra in Spain left, he/it didn't have the institutions missed of capitalism challenged enough, Buy Viagra in New York especially the system of the bank, to sustain instead them with the temporary measures of the relief.
On the right, he/it constructs order cheap levitra online the road toward a socialist, welfare state of the European-style, for those.

Of the 17 that have been given a place, Buy generic cialis New York only 11 were again there to the beginning of this school year.
M. that Roffe will debate than a lot more generic cialis Toronto residencies would participate if the plan had been developed generic viagra Cyprus and the local authorities made more to facilitate it.
M. Roffe wants that the ministers generic viagra Amsterdam commit to pay for a subsidy to every child of a vulnerable origin who wins a place at a residency.
This money could be used to pay for generic viagra Switzerland the price of the pension in a residency of the state, or is combined generic viagra Italy with the existing purses and the subsidies of charitable confidences to allow a child to attend a private residency.
If 1,000 children were eligible, the plan generic viagra Hong Kong would cost about ?10m - a "drop in the generic viagra Spain ocean", M. that Roffe will say, compared with expense of the public on social care.

The wild forebears of common buy generic tadalafil online domestic fruit trees are in danger buy viagra low cost to become extinct, the scientists warned.
The researchers published a "red list" buy viagra Canada online of threatened species that grows in the forests of Asia Centrale.
These trees greengrocers illness purchase sildenafil citrate online resists and climate tolerates could play a role in our future security of food.
But roughly 90% of the forests have been buy cialis Canada online destroyed in the last 50 years, according to charity of the conservation, order viagra online now Fauna & Flora International.

The proportion of adult learners in the discount price viagra online UK is at its lowest level since Labour came to power, a survey suggests.
