    ok - that's right
    i forgotten this difference

    Maybe you can use a different Proxy (RpcProxy) to do server-side reloads?

    Question 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 . . .

    there is an LiveGrid planned from Ext GWT for 2.1 (roadmap), you may want to await for that?

    Default Active grid ported successfully on GXT 2.0

    Active grid ported successfully on GXT 2.0




    I was able to run this active grid on gxt2.0, what all i was missing is the CSS link for scroll bar due to which i was going in infinite loops.

    regards,

    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.

    Is it possible to send this file to me?

    It would be a huge favor.

    Please, could you post the ported active grid code?.

    Thanks a lot, Iván.

    Default Odd refresh issues with many columns

    Odd refresh issues with many columns


    Hi,

    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.

    Thanks,
    Matt

    Hello,

    The on-line demo link isn't available.
    What are the steps to integrate your ActiveGrid?

    only put the jar in my library directory ?

    Hi Valery,

    GXT 2.1 now has Live Grid functionality so the Active Grid plugin is no longer required. I am using the Live Grid and can confirm that it works well.

    See http://www.extjs.com/examples/explorer.html for the demo.
