Killer WDDX - Beware!

I came across a rather interesting 'feature' tonight while working on some logging and alerting processes. We have data in a structure that holds raw information about various processes that have occurred. In one of the structure keys there is an XMLObject (coldfusion parsed xml object). See the code snippet below and DO NOT run this on production equipment!!

<cfset stcStruct = StructNew()/>

<cfset xmlDoc = "<myxml><name>Kevin Penny</name></myxml>">
<cfset stcStruct.xml = xmlParse(xmlDoc)/>
<cfset stcStruct.id = 1>

<cfwddx action="cfml2wddx" input="#stcStruct#" output="tmp"/>

This takes a Structure, adds a key of 'xml' and places a parsed xml object in it's position. I'm then serializing the data into wddx via cfwddx as cfml2wddx.

I originally thought it was the date fields that I had in the structure, so I removed those, but the problem was the xml object's serialization.

Here's the error I get along with a partial dump:
java.lang.StackOverflowError

I've submitted this as a bug to Adobe #75230.

Update to CFPROPERTY Inspector Utility

I implemented a new UI for the CFPROPERTY Inspector as well as small bug fixes etc.

I used the JQuery tab UI which helps the flow of the steps being that the process is just one large form. Here are the new screen shots.

CFProperty Inspector on RiaForge

I've released the CFPROPERTY Inspector on riaforge and google code for those interested in it.

This Utility is designed to introspect components and auto-create CFPROPERTY tags based on the function meta data.
Specify the mapping to your components, and choose which cfc's you want to have CFPROPERTY Tags defined on them as well as what properties of your components that you wish to have CFPROPERTY tags defined for. (for assisting in getting your components well defined for Flex integration etc.)

For Screen Shots and more checkout cfproperty.riaforge.org and to download the code visit Google Code here.
