Never mind - that was a dumb question... the filterBy call is actually on "data" which is a MixedCollection and has a similarly named method filterBy.

[by Nightwish]

I was looking through the Ext source code trying to understand how filtering in stores works and noticed the following two functions in Ext.data.Store:



filterBy : function(fn, scope){

The API docs page http://dev.sencha.com/deploy/dev/docs/ returns an empty page for me. My bookmark stopped working so I went to the page through the sencha.com site - same result. Tried it in both...

I've got a simple window with a form in it - validation messages are shown UNDER the form fields because I like users to see what the errors are without hovering on icons.

Both window and form...

Condor, may I say that you are a God among men =D And I can't believe I made such a noob mistake. Thanks for your help.

Hi Condor,

The tree does not have a fixed height. Here's the order in which tree and other panels are nested:

TreePanel (as tab) -> TabPanel -> Container (West) -> Viewport

Many ways to do it depending on the original event coming from the grid - click, select, doubleclick, etc. You can always add a listener for one of these - the listeners are always called with the...

I've got a simple tree - nothing groundbreaking, works perfectly fine in Firefox and fails miserably in IE8. No JavaScript errors are shown - the tree simply doesn't render any nodes.

Here's the...

I found it and it almost poked out an eye: "sortable: true" needs to be explicitly defined for every grid column.

[by Nightwish]

Despite repeated efforts I've been unable to figure out why some of the columns in my grid have their sorting options (Sort Ascending, Sort Descending) grayed-out. Even if I wanted to disable them I...

Thanks, Animal... of course, I looked at the help files, FAQ, forums, etc. before posting. I found my problem and it's not very obvious to the ExtJS novice. Apparently, the JSON response is...

I've been thinking for a while and looking at the examples but I've been unable to find a clean, elegant solution for this admittedly simple and common scenario.

Imagine a form - validation is...

Have you considered templates? Here are some examples:

Awesome - "actioncolumn" would be a welcome addition! Is there a release date set for 3.3?

[by Nightwish]

All the /ux/ files are extra plugins and components that do not come with the main ExtJS library.

You are creating a new tree. Give the existing tree an ID ("categoryTree" in my example) and use it instead. Try this:



function test()
{
var tree = Ext.getCmp('categoryTree');

Well, that's embarrassing - the solution is actually in the API documentation. The setUrl function on the proxy can be used to change the url permanently.



onDataTreeClick: function(node, e)...

It's either that or I am doing things completely wrong.

I've got a tree and upon clicking a leaf in the tree a grid is refreshed with new data (url is a parameter on the leaf). The grid refreshes...

Is there a place where we can go and see what is being changed in each version? If there is no such place - can we have one? A quick forum post, static html, text file, what have you...

Found the problem - the itemSelector setting was lost when the project was converted from Ext Designer 1.01c to 1.02. One of many many problems during the conversion.

The DataView is populating just fine from the store but when I click on a node I can see in Firebug that the index passed to the click handler is -1. What could be going wrong here? This code used to...

Marcus, this is very useful - thanks for the tutorial!

This was a bit of a surprise but since Ext.form.Action.Submit does not support submissions in JSON I decided to use the solution proposed here:
