Hi all,

I have had similar issues with the add/edit features of the random link tutorial. I have managed to somehow store two results in the db, but now i can't edit or add a new link. stepping through the javascript using firebug i am having issues with
$("SwitchView") is null
on line 437 of leftandmain.js

Anyone got any ideas how i can fix this issue?

Thanks in advance!

Example of sitetree randomlinks filter - button with filter text field (can be usefull for huge number of items in tree).

RandomLinksAdmin_left.ss:

<div id="treepanes" style="overflow-y: auto;">
<ul id="TreeActions">
<li class="action" ><button id="filterlink">Filtruj</button>
       <form class="actionparams" id="filterlink_options" style="display: block" action="admin/randomlinks/filterlink">
       <input type="text" name="filter"/>
       </form>
</li>
<li class="action" id="addlink"><button><% _t('CREATENL','Create New Link xXx') %></button></li>
<li class="action" id="deletelink"><button><% _t('DEL','Delete Link xXx') %></button></li>
</ul>
...

RandomLinksAdmin_left.js:

_HANDLER_FORMS['filterlink'] = 'filterlink_options';

filterlink = {
button_onclick : function() {
filterlink.form_submit();
return false;
},

form_submit : function() {
Ajax.SubmitForm('filterlink_options', null, {
onSuccess : function(response) {
$('sitetree').innerHTML = response.responseText;

$$('#sitetree li').each(function(n) {
$('sitetree').SiteSubTree.castAsTreeNode(n);
});

},
onFailure : function(response) {
errorMessage('Error filtering', response);
}
});

return false;
}
};

Behaviour.addLoader(function () {
Observable.applyTo($('filterlink_options'));
$('filterlink').onclick = filterlink.button_onclick;
$('filterlink').getElementsByTagName('button')[0].onclick = function() {return false;};
...
