How to concatenate an Ext.JS method inside a tpl string?

[imcl]

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


For example:

    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?

    itemTpl: [
        ...
        '<tpl switch="post_type">',
        '<tpl case="new_user">',
            '<p>{post_text_teaser}</p>',
            '<p>{timestamp}</p>',
        '<tpl default>',
            '<p>{[Ext.String.ellipsis(values.post_text_teaser,4)]}</p>',
        ...
    ].join(''),
