the remove function can take 2 arguments. The 1st is the component to remove, the 2nd is the autoDestroy flag. If not specified it defaults to the container's autoDestroy value, which defaults to true for Ext.Panel So when you remove the grids from the grid container you are destroying them and they are not available for further use. You need to either set the 'autoDestroy' config property of the grid container panel to false or else specify the 2nd parameter as false in the remove function calls.

With the code below I can start the application and the grids are loaded according to which tab is activated. The problem is that I can only do it once! If I change from from the first tab to the second tab....and then back to the first tab, the grid in is not activated!?!? I´m sure there is a simple explanation...i hope. Can anyone see it? The app is here... http://maps.zgb.de:8080/geoserver/www/testing/wea_tabs.html var centerTabPanel = new Ext.TabPanel({ id:'centerTabPanel', region:'center', width: 800, activeTab: 0, items:[mapPanel_wea, mapPanel_biogas, mapPanel_wasser] }); centerTabPanel.items.each(function(tab){ tab.on('activate',function(panel){ if (panel.id == 'WEA') { // Ext.Msg.alert('Panel', panel.id + '" tab?'); gridContainer.remove(grid_wasser); gridContainer.remove(grid_biogas); gridContainer.add(grid_wea); gridContainer.doLayout(); } else if (panel.id == 'Biogas') { // Ext.Msg.alert('Panel', panel.id + '" tab?'); gridContainer.remove(grid_wea); gridContainer.remove(grid_wasser); gridContainer.add(grid_biogas); gridContainer.doLayout(); } else if (panel.id == 'Wasserkraft') { // Ext.Msg.alert('Panel', panel.id + '" tab?'); gridContainer.remove(grid_wea); gridContainer.remove(grid_biogas); gridContainer.add(grid_wasser); gridContainer.doLayout(); } }); }); Thanks for any help, Robert -------------------------------------------------------------------------------- _______________________________________________ Users mailing list [email protected] http://www.geoext.org/cgi-bin/mailman/listinfo/users
