Hi,

I'm using Infragistics v12.1.

I have this webExplorerBar:

<ig:WebExplorerBar ID="webMenu" runat="server" EnableSelection="true" EnableViewState="true"                                                                             GroupExpandAction="HeaderClick" StyleSetName="RubberBlack" Width="280px" ViewStateMode="Enabled" OnPreRender="webMenu_PreRender" >
   <ClientEvents ItemClick="ctl00_webMenu_ItemClick" AJAXResponse="ctl00_webMenu_AJAXResponse"                                                                                    ItemCollapsed="ctl00_webMenu_ItemCollapsed" ItemExpanded="ctl00_webMenu_ItemExpanded" />                                                                             
   <DataBindings> 
       <ig:ExplorerBarItemBinding DataMember="Groups" KeyField="GroupName" NavigateUrlField=""                                                                                     TextField="GroupName" ValueField="IDGroup" /> 
      <ig:ExplorerBarItemBinding DataMember="Items" ImageUrlField="ImageUrl" KeyField="ItemName"                                                                                     NavigateUrlField="NavigateUrl" TextField="ItemName" ValueField="IDItem" />                                                                                                                                                         

.....
   </DataBindings>                                                                            
   <AutoPostBackFlags ItemClick="Async" ItemSelected="Async" />                                                                        
</ig:WebExplorerBar>

It works fine on IE. I click an item in the Menu and everything is OK.

When I try the same on firefox I got this message: Async request failed

This only happens if the AutoPostBackFlags are set to Async or On. If I set them Off, it's ok on firefox. But I need these to be ON.

What can I do to avoid this warning?

Thank you
