I want to touch on a subject that I know that not many people actually take into consideration, and that is how to deal with errors and other problems on the server when being called by a remote client call.
I am going to state that I am defining any call made as either a web service, remote procedure call, rest calls that is either from a client like a JavaScript call or even Flash, Flex or anything else.
So how do we handle them, should we report them to the caller or should we just log the call somehow on the server.

Over the last couple of days I have been working on a very small research project, the idea was to just to get familiar with phoneGap and ExtJS Touch. But before I worked on the mobile side of the code, I wanted to just get familiar with the new data model in ExtJS 4.0.
I had been reading about this new feature for awhile now, and wanted to try reading a stream of xml data and store it into the data model. The first attempt the XML was just dummy nodes, with an array of children and it worked very well. So after getting the hang of this I began placing the dummy data with the real data, and discovered that the power of ExtJS is beyond imagination.
So lets take a look at how the new data model works.

A little while ago I posted about this problem and after digging into it further, found here ColdFusion and debugging ColdFusion 9 Ajax calls with the line debugger. Since then I have done a bit more digging around and found that for some reason in ColdFusion 9 there is an extra URL paramter being passed via the AjaxProxy.

Today we had an interesting discussion on this very subject, now we already have one in place. Yet we have varying opinions on why we should do something, but nothing really concrete as the real truth as to why it should be this or that way. I personally have grown to love the fact that the beginning of a block is on the same line as the method, component class or loops etc. My logic behind this is that it is neater, doesn't clutter the workspace and fairly easy to read.
However my logic just doesn't end there.

Following on from a previous post I made about the comparisons between ExtJS and jQuery, I thought I would go into a bit more detail with some of the other features that the two frameworks offer.

I have been working on a ColdBox application for a few months now, which has a lot of Ajax calls when a user is signed in. The one thing that I have not really handled, is how do I tell the browser that the users session has timed out.
ExtJS can make this very easy, and the code that I am showing will work in both ExtJS and ExtJS Core.

In a previous post I talked about how there isn't much of a difference between ExtJS Core and jQuery, and today I am going to go through some of the syntax used for doing some DOM work in both.
Before I go and discuss this I would like to also point out one thing, only because I am not sure people are actually aware that ExtJS Core is a completely separate package to ExtJS. As with jQuery it is also very free to use in your applications.

There is a lot of support on both sides to this argument, and one that really at the end of the day comes down to user preference. One of the myths that does surround extJS is that it has a huge footprint and is bloated, this is not true and in fact ExtJS Core is not that much bigger than jQuery.
The decision to use either is really down to personal preference and the support that each of these products do offer, as well as what type of application you are looking at developing.
if you are looking at just doing simple DOM manipulation then both have their strengths, and are of around the same footprint in terms of size. Personally I think ExtJS also offers a lot more out of the box and which can attribute to its slighter higher file size difference.
So what is best for me in terms of development.

In my second instalment to writing and using ExtJS that comes with ColdFusion, I am going to begin by building a custom widget that can retrieve Frequently Asked Questions from the server, based on what the user enters as a search Criteria.

This is the beginning of a series of tutorials that I will be writing that shows how to use ExtJS that comes with ColdFusion, in both ColdFusion 8 and 9.

I thought I would post this very quick Ajax tutorial and how easy it is to use, without using any extra frameworks or JavaScript libraries that don't already come with ColdFusion.
