Knockout.js and why Flex devs should try it.

Being primarily a Flex developer at work, I take great pleasure in the opportunities I have at the workplace to use different technologies to get the job done. Recently, I developed a simple internal application that I could have done in Flex, but really, it was fairly straightforward and I wanted to brush up on…


NativeMappedSignal (map that shit!)

I have had the pleasure of using AS3-Signals in combination with Robotlegs for quite a while now. It’s a great combo for communication within a Flex Application. I was at one point hesitant about using signals for communication within my components, until I started experimenting with them. You can check out the Community Examples page…


Drag and Drop Services to Map

Recently a conversation came up at work about making a tool that would allow us to drag and drop any of our existing Map Services on our ArcGIS Server to a Map using the ESRI Flex API 2.0. It wasn’t critical, but I had a bit of downtime today and after some tooling around I…


Map Legend and Layer Control for ESRI Flex API 2.0

As GIS professionals when we make maps, one of the most critical components to that map has always been the legend. I have head the statement before that If your map needs a legend, there’s something wrong with your cartography. Yeah right, maybe if you’re making a street map, but when you are building analysis…


FlexMapTools and git issues

So I had an oops moment when apparently I navigated to my local git directory using all lowercase letters and pushed my commits this evening. Although the folder structure in my local repo and the folder structure when I pulled my repo from github were identical, the github page had a FlexMapTools and a flexmaptools…


F’ing with FMap in FlexMapTools

I’m going to try to use the next few blog posts to go over how I use the tools I’ve provided in the FlexMapTools toolbox I put up on github. The first is the FMap component, which extends the ESRI Map component. This component started as a way to control the position of the ESRI…


FlexMapTools for ESRI Flex API

For a couple of years now, I have been working with the ESRI Flex API to build Flex Mapping applications at work. Over that time, I like to think I have learned quite about programming and Flex/Flash in general. I would consider myself an intermediate and I continue to learn more everyday (more like shoehorn…


Custom GeocodeProcessor with Swiz

One of the interesting features of Swiz 1.0 (still pre-release) is the ability to create custom metadata processors. To get more familiar with the idea, check this docs page. Note that some items from the docs has changed, such as you no longer extend MetadataProcessor, but extend BaseMetadataProcessor. There is a Yahoo Finance Processor, a…


Swignalz!

Recently I decided to take a crack at AS3 Signals. Robert Penner has done some really nice work putting signals together. AS3 Signals is basically meant to replace using custom events to dispatch your payload around. I’m not sure I’m entirely sold on the concept of introducing another API into my apps, but I was…


Highlight Map from List Items

I was inspired by this posting on the ESRI ArcGIS Server Blog filed in the Flex tag, that linked your graphics on a map with a DataGrid. This is a useful function and one I thought could be encapsulated into it’s own task. In my case, I just had a need to highlight a graphic…
