In YiiBootstrap TbGridView, the columns headers are defaulting with ^ for sorting like this.
Its mentioned in the file \protected\extensions\bootstrap\widgets\TbDataColumn.php on the line 28 like
if ($sort->resolveAttribute($this->name) !== false) $label .= ‘<span class=“caret”></span>’;
In the original extension ext.eziiui.widgets.grid.CGridViewUI , it used to change to a down or up arrow depending upon the sort clicked on column header and no arrow when sort is not clicked.
Is there any fix available to this problem ?
