I have downloaded ActiveGrid example and facing problem to run it on GXT 1.2.4
[ERROR] Errors in 'jar:file:/D:/ext-Gwt/gxt-1.2.4/gxt.jar!/com/extjs/gxt/ui/client/widget/selection/AbstractStoreSelectionModel.java'

activeGrid reponses in infinite loop without rendering in the grid
activeGrid reponses in infinite loop without rendering in the grid
Hi
I have ported the activegrid code in gxt 2.0 with gwt 1.6.
Initially i am using only 2 files from the jar; activeGrid and activeGridview without toolbar etc. I am able to get the grid window and column titles initially but without data. Later on the grid data is requested in infinite loop, response reaches but the data is not shown/rendered in the grid.
pointers and help would be appriciated . . .

Reason: typo
For some reason I can't download the zip file and extract it properly. When I try to extract it can not find anything to extract. I tried it 10 times at least.

Please, could you post the ported active grid code?.
Firstly, thank you so much for writing ActiveGrid. I have downloaded the alpha code, fixed up a few compilation errors to get it to work with GXT 2.0.1 and all is dandy.
However, there are odd refresh issues that present themselves when I scroll vertically once I have scrolled horizontally (I have many columns), which I'm wondering if you've seen before or if you have any advice.
My configuration is this:
One large border layout
Central panel contains ActiveGrid
Left panel contains operations (currently empty)
ActiveGrid contains 31 (!) columns, with column groupings
Buffer size of 200, with 20% pre-fetch
Data set of ~30,000 rows
When I scroll through the grid with the horizontal position at the default far left, all is well. However when I move to the far right, the entire viewport briefly flashes. Additionally, the horizontal scrollbar often shifts back to the left hand side.
Starting from the top and scrolling down row by row with horizontal scrolling at far right, I get to around four or five rows before the horizontal scrollbar jumps left again. Playing around with this a bit further, and the grid started rapidly scrolling left and right. Now Firefox is at 99% CPU and very unhappy indeed.
Any ideas? I'm a rank amateur with GXT so am not sure where to start.
FWIW, I was previously using Ext JS with the LiveGrid module and the same size dataset, and have never experienced problems of this nature.
This table - and the data manipulation operations I am going to build around it - is key functionality for a major one-year project, so I am very keen to get this working well. I recently stopped developing this using Ext JS and started migrating to GXT because of maintainability / debugging / unit testing concerns, however if I can't resolve this I will be forced to drag out the Ext JS code again :/
Whereas I'm a GXT newbie, I'm an experienced Java developer so am more than happy to assist with work around ActiveGrid if required.
