    Default Grid with AggregatioRow and GroupSummaryView error in Internet Explorer

    Grid with AggregatioRow and GroupSummaryView error in Internet Explorer


    Hi,

    the code below generates an error in Internet Explorer, but not in FF or Chrome, where the totals are disaplayed correctly. If I remove the totalsRow code then the code works fine... Any help appreciated, thanks.

    In development mode IE I get the following error:

    Code:
    07:35:39.409 [ERROR] [XXXXXXXXXXXXXXXXXX] Uncaught exception escaped

    Maybe you can try to compile that with this flag enabled:
    -style DETAILED

    This provides better debugging info.
    Maybe that an help you identify the source of the error.

    Which version of GXT are you using? Can you try to reproduce this in a small, standalone example thati mlpements EntryPoint? There was an issue in GroupSummaryView prior to GXT 2.2 which can course this. If you are not using GXT 2.2, try updating to it.

    Thanks,

    I downloaded the new 2.2.0 version and I am getting nightmarish errors from the gxt jar. Please see the post

    http://www.sencha.com/forum/showthre...279#post513279

    I will come back to this thread once the migration issues are fixed.

    Thanks,

    The problem still exists after the migration... The problem appears when I call the layout() method of the parent LayoutContainer if the grid has the AggregationRow defined. I am badly stumped

    Can you please post a fully working testcase that implements EntryPoint than? This page uses aggregationrows but does not throw an exception: http://www.sencha.com/examples/explo...egationrowgrid

    I took your code and made it work for me (as i dont have all your depencies) and it worked.
    In which context do you use the code?

    I have a ContentPanel inside a TabItem. The ContentPanel has a VerticalPanel which contains two elements, the grid that's giving me problems and a chart. The problem appears if I add the AggregationRow to the ColumnModel. I must call the layout method explicitly because I want to add the grid only if the user really wants to see the data inside it, not when I add it to the VerticalPanel. As I said the error only appears in IE. FF and Chrome are fine...

    I have adapted and implemented the code below from the examples and it works.... the code in my previous post does not work...

    The call to layout is cached and is doing nothing. You also dont have to call reconfigure in your code. However, this code does not throw any exception for me.

    Uhmmm... The error happens when I call layout(), in FF, where the code works, if i don't call layout the grid is never displayed. Also, i need to call reconfigure to force the header to update with the new labels coming from the server. Basically the idea is that I add the VP to the CP. The grid is added to the VP only after the first time the user asks the server for data (i.e. only when it's needed), hence the reason why I need to call layout() to actually show the grid.

    Thanks for your help... I will see what I can do, will let you know if I make it...

    I was referecing to your example code now (i dont know anything else than this). And there, layout is unneeded, as the grid was already rendered by the first time.
