ExtJS RowExpander plugin: expanded rows looses it's row body on grid refresh (with enableCaching: false)

[gadgetto]

Summary

We have a MODX grid with rowExpander plugin enabled and enableCaching: false. If row is expanded and the grid is refreshed, the expanded row seems to collapse but the [+] sign stays at [-]. You then have to click the [-] and then the [+] to re-expand the row.

This problem is also related to: #13989

Step to reproduce

Setup a MODX grid and create a rowExpander:

    // Content of the expanded grid row
    var nlInfos = [
        '<table id="gon-nlinfo-{id}" class="gon-expinfos">',
            '<tr>',
                '<td class="gon-expinfos-key">'+_('goodnews.id')+'</td><td class="gon-expinfos-val">{id}</td>',
                '<td class="gon-expinfos-key">'+_('goodnews.newsletter_createdon')+'</td><td class="gon-expinfos-val">{createdon_formatted}</td>',
                '<td class="gon-expinfos-key">'+_('goodnews.newsletter_publishedon')+'</td><td class="gon-expinfos-val">{publishedon_formatted}</td>',
                '<td class="gon-expinfos-key">'+_('goodnews.newsletter_sender')+'</td><td class="gon-expinfos-val">{sentby_username}</td>',
                '<td class="gon-expinfos-key">'+_('goodnews.newsletter_scheduled')+'</td><td class="gon-expinfos-val gon-scheduled">{pub_date_formatted}</td>',
            '</tr>',
        '</table>'
        ].join('\n');

this.exp = new Ext.ux.grid.RowExpander({
    tpl: new Ext.Template(nlInfos)
    ,enableCaching: false
});

Please note: if you set enableCaching: true it works as expected - except that the fields in the expanded row aren't updated!

Bind it to the MODX grid:

        ...
        ,plugins: [this.exp]
        ,columns: [
        this.exp
        ,{
            header: _('goodnews.id')
            ,dataIndex: 'id'
            ,hidden: true
        ...

Observed behavior

If row is expanded and the grid is refreshed, the expanded row seems to collapse.

Expected behavior

The row should stay expanded on grid refresh and the expanded content should be refreshed too.

Environment

MODX version: 2.6.4-pl
Browser: tested in Safari and Chrome

Hi @gadgetto
Did you try also set lazyRender to false? I tried and all works fine for me. Please, try and confirm.
It seems that it is not an issue and can be closed.
