Why am I getting error "addRowExpansionRenderer is not a function" in the JavaScript web framework after upgrade to Splunk 6.3 from 6.2.4?

[ConnorG]

After upgrading to Splunk 6.3, it seems the previous web framework for Javascript does not work properly.

My jscript is getting a TypeError: tableView.table.addRowExpansionRenderer is not a function error when being run under a 6.3 instance.

The code I'm using is expanding upon the concepts provides here

Anyone know if there were changes to the web framework and how to accommodate those changes?

I fixed it after referencing the example dashboards app. Below you can find my code.

6.2.4 code:

var tables = ['web_stat_page_tbl', 'web_diag_tran_tbl', 'web_diag_comp_tbl', 'web_stat_tran_tbl'];

    for(i = 0; i < tables.length; i++) {
        mvc.Components.get(tables[i]).getVisualization(function(tableView) {
            // Add custom cell renderer
            tableView.table.addCellRenderer(new CustomRangeRenderer());
            // Add custom row renderer
            tableView.table.addRowExpansionRenderer(new CustomRowRenderer());

            // Force the table to re-render
            tableView.table.render();
        });
    } 

6.3.0 code:

    var tableElement = mvc.Components.getInstance("web_stat_page_tbl");
    tableElement.getVisualization(function(tableView) {
        // Add custom cell renderer, the table will re-render automatically.
        tableView.addCellRenderer(new CustomRangeRenderer());
        tableView.addRowExpansionRenderer(new CustomRowRenderer());
    });

Sticking to the old format would give us:

    var tables = ['web_stat_page_tbl', 'web_diag_tran_tbl', 'web_diag_comp_tbl', 'web_stat_tran_tbl'];

    for(i = 0; i < tables.length; i++) {
        mvc.Components.get(tables[i]).getVisualization(function(tableView) {
            // Add custom cell renderer
            tableView.addCellRenderer(new CustomRangeRenderer());
            // Add custom row renderer
            tableView.addRowExpansionRenderer(new CustomRowRenderer());

        });
    }

Below is the table object in a debug view coming from Splunk 6.2.4. Here we can see the addRowExpansionRenderer is still listed under the object.

Here is the same object in 6.3. No mention of RowExpansionRenderer anywhere.
