How to add a lense icon to multiple tables with the same Javascript?

[swaro_ck]

Hi,

Inspired from this post: https://community.splunk.com/t5/Dashboards-Visualizations/How-can-i-re-use-Java-scripts-form-one-tab... I modifed my Javascript to add a lense icon in two tables. Same fieldname "Metrics" same icon "lupe.png" but 2 different tables. With Splunk 8.1 it's working without any error.

After the upgrade to 8.2.9 I get now this error message by accessing the App but the lens icons are still shown in both tables.

The output from the developer console:

TypeError: Cannot read property 'getVisualization' of undefined at eval (eval at <anonymous> ...

table_lupe.js

require([
    'underscore',
    'jquery',
    'splunkjs/mvc',
    'splunkjs/mvc/tableview',
    'splunkjs/mvc/simplexml/ready!'
], function(_, $, mvc, TableView) {
    var CustomIconRenderer1 = TableView.BaseCellRenderer.extend({
        canRender: function(cell) {
            return cell.field === 'Metrics';
        },
        render: function($td, cell) {
            var icon = 'lupe';
            // Create the icon element and add it to the table cell
                $td.addClass('icon').html(_.template('<div class="myicon <%- icon%>"></div>', {
                icon: icon,
            }));
        }
    });
    var CustomIconRenderer2 = TableView.BaseCellRenderer.extend({
        canRender: function(cell) {
            return cell.field === 'Metrics';
        },
        render: function($td, cell) {
            var icon = 'lupe';
            // Create the icon element and add it to the table cell
                $td.addClass('icon').html(_.template('<div class="myicon <%- icon%>"></div>', {
                icon: icon,
            }));
        }
    });
    mvc.Components.get('lupe1').getVisualization(function(tableView1){
        // Register custom cell renderer, the table will re-render automatically
        tableView1.addCellRenderer(new CustomIconRenderer1());
    });
    mvc.Components.get('lupe2').getVisualization(function(tableView2){
        // Register custom cell renderer, the table will re-render automatically
        tableView2.addCellRenderer(new CustomIconRenderer2());
    });
});

table_lupe.css

/* Custom Icons */

td.icon {
    text-align: center;
}

td.icon .lupe {
    background-image: url('lupe.png') !important;
    background-size:20px 20px;
}

td.icon .myicon {
    width: 20px;
    height: 20px;
    margin-left: auto;
    margin-right: auto
}

Maybe some one can help me find whats the problem.

Thank you.

    'splunkjs/mvc',
    'splunkjs/mvc/tableview',
    'splunkjs/mvc/simplexml/ready!'
], function(_, $, mvc, TableView) {
    var CustomIconRenderer = TableView.BaseCellRenderer.extend({
        canRender: function(cell) {
            return cell.field === 'Metrics';
        },
        render: function($td, cell) {
            var icon = 'lupe';
            // Create the icon element and add it to the table cell
                $td.addClass('icon').html(_.template('<div class="myicon <%- icon%>"></div>', {
                icon: icon,
            }));
        }
    });
    var tableIDs = ["lupe1", "lupe2"];
    for (i=0;i<tableIDs.length;i++) {
        var sh = mvc.Components.get(tableIDs[i]);
        if(typeof(sh)!="undefined") {
            sh.getVisualization(function(tableView) {
                // Add custom cell renderer and force re-render
                tableView.table.addCellRenderer(new CustomIconRenderer());
            });
        }
    }
});

I hope this will help you.
