Hi all, any news about it?

We tried to add a GridTreeContainer into a GridTree, but on screen does not appear nothing.
After that we tested using a simple Grid with the same container and the data appeared.

I guess GridTree has a problem with Java 7.

I"ve changed the project to use maven instead of Ivy. Now it should work. I’ve created a simple Vaadin project (see the attachment.) You can also refer to github to gridtree-demo project to see more complicated example, shown in the demo page. I’ve changed the code to use Java 7 and now I myself use Java7, so it should not be a problem now.

Remember to compile both theme and widgetset after adding addon.

The latest version should be 1.0.3.alpha3. Not much changes there just changed the project tool from Ivy to maven because had some strange problems with Ivy.

So, I will force the maven to update the library again…

Ok, please reply on results, now you should be able to create a very siimple application using the component.
There was some mess with the versions, sorry about that.

We try to use this plugin with JPAContainer, on table with 5 million rows, table try to load all rows (!!!). Why implementation is not lazy? How i can tune it to lazy loading?

It looks like there is a problem in the Container. I’m using getItemIds(), which basically loads all the items. I’ll take a look at it and fix it ASAP.

Hi, is it possible to but a filter in that ? Could be an integration with GridCellFilter addon. I’ve tried but the GridTreeContainer can’t be used, because is expected a Filterable container. What do you thing about a new version with this improvement ?

Thanks a lot

Diogo Lopes, hello.
There are several issues with this addon which I could not come up with any solution, the biggest one is lazy loading from the database. That’s why the addon is marked as experimental. Honestly, I don’t know when I’m gonna return back to it. The addon was not really popular, so it’s not under development for a long time. Sorry about that.
I’ve just published the addon and sources, so it can be used as a foundation for some other work.
