extjs - Ext JS Component - When can I manipulate the DOM? -


I'm trying to reuse some code to return a component to its initial position so that my Close is a reset () function that calls the update () function with the default parameter.

Everywhere I try, I'm trying to reach the DOM elements, results in the null - and this is not the code as I tested it after page presentation via page event. It seems that initComponent () is very fast, so I've noticed subscribing to events.

Seeing the events of Ext.Component , only one seems appropriate Render Event: "After the component markup, the fire is set. "

Again, I get a null reference. I am not keen to use it because I really want to use render, not to it being sung again, its only once (init after / after), but it can be said again.

When / We want to access the DOM of component on initialization?

Here's the square: 

  Ext.define ('PegfileApp' View.ContentHeader ', extension:' Expand panel ', nickname:' Widget Content Header ', ID: 'Content header', // layout limit: 1, html: "\

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
