I would like to use Ext's String method on some text that will be output to the view.


For example:


Code:
    itemTpl: [
        ...
        '<tpl switch="post_type">',
        '<tpl case="new_user">',
            '<p>{post_text_teaser}</p>',
            '<p>{timestamp}</p>',
        '<tpl default>',
            '<p>' + Ext.String.ellipsis( + '{post_text_teaser}' + \, 4) + '</p>',
        ...
    ].join(''),
but of course the concatenation in line 10 is illegal.


Do you know if it's possible or how to do this correctly?
