- When there is only one item in the trash, the 'select all' checkbox won't select/unselect that item.

- When there are multiple items, the checkbox is working fine in Firefox, but in IE 6 (and probably 7 too) the items won't get selected directly. A second click on some other part of the screen will trigger the items to get selected though.

 - When there are no items, clicking on the check box will generate a javascript error.

This is my suggested fix. Edit WebGUI::Asset::www_manageTrash (WebGUI/lib/WebGUI/AssetTrash.pm) to:

1) monitor the removed event instead of onchange 

   <script type=\"text/javascript\">
   //<![CDATA[
     var assetManager = new AssetManager();
         assetManager.AddColumn('".WebGUI::Form::checkbox($self->session,{name=>"checkAllAssetIds", extras=>'removed="toggleAssetListSelectAll(this.form);"'})."','','center','form');
         assetManager.AddColumn('".$i18n->get("99")."','','left','');

 2) replace the definition of the javascript function toggleAssetListSelectAll with:

 function toggleAssetListSelectAll(form) {
    assetListSelectAllToggle = assetListSelectAllToggle ? false : true;
    if (form.assetId) {
        if (typeof form.assetId.length == "number") {
            for(var i = 0; i < form.assetId.length; i++) {
                form.assetId.checked = assetListSelectAllToggle;
            }
        }
        else {
            form.assetId.checked = assetListSelectAllToggle;
        }
    }
}
