Important

This plugin requires that the viewer is configured as Ext.TabPanel

This is the code that checks for this requirement in app/templates/composer.html:

            ...
            //check if MetadataExplorer plugin is defined in customTools configuration
            var customToolsME = [];
            if(serverConfig.customTools){
                for(var cTools in serverConfig.customTools){
                    if(serverConfig.customTools[cTools].ptype == "gxp_metadataexplorer"){  
                        customToolsME.push(serverConfig.customTools[cTools].ptype);
                    }
                }
            }
            
            //check if MetadataExplorer plugin is defined in tools configuration
            var toolsME = [];                
            if(serverConfig.tools){
                for(var tools in serverConfig.tools){
                    if(serverConfig.tools[tools].ptype == "gxp_metadataexplorer"){  
                        toolsME.push(serverConfig.tools[tools].ptype);
                    }
                }
            }            
            
            if(!serverConfig.tab && toolsME.length == 0 && customToolsME.length == 0){
                appTabsOpts.layout = 'fit';
                appTabs = new Ext.Panel(appTabsOpts); 
            }else{
                appTabs = new Ext.TabPanel(appTabsOpts); 
            }
            ...
