To who is web developer, no matter is it Flex, Flash, Java, HTML, and use Firefox as browser, there is an extension which is a MUST-HAVE.
Plugin enables you to control all aspects of broswser and page contents details, like enabling/disabling cache, forms, styles and much more.

Web developer extension

When installed, it will be placed in TOOLS menu.

Seems that FF3 has a slight problem with cache handling due to anti-phishing algorythms. I found this somewhere on the net, and it really works.

Go to FF preferences -> Security and un-check 2nd and 3rd checkbox,
“Tell me if …”

Close preferences and close Firefox.
Go to your users settings where firefox keeps it’s files for the account. I Windows should be somewhere in “Application Data”, I am not sure, but for Linux, open terminal and write
#> cd .mozilla/firefox
and enter in tou your account directory (should be something like “of6wel65.default”) , name is pretty random.

- Delete files urlclassif*.sqlite
- Start firefox.

that is it.

Mozilla labs addressed a call to all people to participate in ideas and collaboration for the next generation web browser. Call can be viewed here:

There is a case when one needs to make a structural representation of data which resides in a single table, with records referenced to one another. This is not difficult to make, but sometimes people just doesn't have time.

I had small table with linked records, that I had to represent structurally. Table was something like:

where record Id 2, links to record Id 1,  by third field.

I have found a component on the internet from Singapore Flex Usergroup, but it didn't worked for my case as I needed to.
So I took the liberty to alter the component and share it.

D-Click developers already have this component set in flex_library.

You may download small Flex3 demo application along with the component from following link:

Last night, I lost a few hours and two kilogramms of nerves to solve the problems I didn't even supposed to have. Something was wrong with the debugger and I couldn't get the job done as debugger was highly uncooperative. Some of the issues were:

• Clicking on one line to toggle breakpoint, it appears in another
• Debugger skips the lines
• Changes in code sometimes doesnt't effect the results in the firefox
• Feeling of a Gremlim infestation of your putter.

Some of you may laugh, but for the certain things, I didn't have any knowledge of, and I didn't find it anywhere, until my collegue Henrique Marino came to explain me how to end the suffering.

So, hereby I share it with you.

1. If you have a CVS controlled code, with a branches, be sure that compiler is set to the particular branch that you work on at the moment. Go to (eclipse) Project -> Properties, select Flex Compiler and see what is written in "Additional compiler arguments". Problem is probably there. This is the reason of debugger skipping the lines, if it is set wrongly.
2. Close all projects except the one you use at the moment. Right click on a project and select "Close unrelated projects"
3. If you use Jetty, since it's not doing boring and time consuming deployment as JBoss, it creates another flaw: cache might not be cleaned. Go to Firefox, Tools -> Web developer -> Disable -> Disable cache.

This will kill the Gremlin(s).

I hope this post will shorten one's suffering.

I just talked to Sub-Zeb. Nowadays, he works for Roundarch and guess what he uses to develop Rich Internet Applications: Adobe Flex.

Pek Pongpaet, who I talked some minutes ago, is Lead Interactive Developer at Roundach. But what is really interesting about Pek is that he did motion capture in five Mortal Kombat games. On his blog you can see some videos.

Well, I couldn't resist the idea to post saying that Sub-Zero works with Flex. Now, I am going to talk to my nephews that I just talked to Sub-Zero. It's a small world.

This is a test to have our blog in english.
