Important Links for Grails

Submitted by prhodes on Tue, 04/14/2009 - 12:49

It's so crazy that this is not easily found or published on the grails site.  There is an argument for using the maven site generator since this type of stuff can be found in a standard location in the site navigation.  Grails should take a lesson here, convention over configuration;)  (this is tongue in cheek)

Here's the slideshow from the PittJug meeting of April 19th.


I also created a new google code project that contains all the GWT/Phonegap code.  While there is another project out there there is a phonegap/gwt, i was far down the road with my own when the started.

 

phonegap and android 2.3 , will not work

Submitted by prhodes on Tue, 01/18/2011 - 01:08

Hey, nice to understand why my app crashes hard when in android 2.3
Phonegap is cool, but no one states the obvious tidbit:, hey guys, you can't use 2.3 because there is a bug in android when it tries to use javascript with a WebView....

android gps in emulator

Submitted by prhodes on Tue, 01/18/2011 - 01:05

This was a show stopper for me.
The android emulator will not return GPS data until you do a "geo fix"
 
While there is lots of info on "geo fix", I would expect the emulator to a least default to google headquarters or something.  Damn you, making me do more work and telneting to my android console.
 

Make sure you return something from your grails actions!

In my grails application, I didn't understand how "index" action was being invoked from another action:

Green Apple Barter - READ THE FINE PRINT

Submitted by prhodes on Fri, 08/27/2010 - 12:45

In my previous posts, I explained how I owed Green Apple Barter a good sum of money for doing pretty much nothing for my business.

I finally "did the math" and decided to end my relationship with Green Apple Barter, and make payment arrangements so that I could pay them what I owe them.  I called my rep and cancelled my membership and promised to pay 100 per month.

editing acquia theme

For the spotmouth.com site, I started by writing a new theme, but in the end, decided to just edit the acquia theme.  One issue that I had was that this theme uses some background images.  While I could  (and initially did) just edit the images to match the color scheme for my design, it didn't feel right.

I wanted to way a way in CSS to remove the background-image that the theme was setting.  I added the following to my local.css and VOILA, it worked:

 

phonegap deviceReady not called in android

Submitted by prhodes on Wed, 08/18/2010 - 13:00

I found several other folks via a google search that experience the same problem.  To summarize, the deviceReady function IS being called, it just is being called super-fast, before your handler is setup to respond to the event.

Here is how I fixed it for the spotmouth android app. I test for the presence of the navigator.device object.  If it's not there, I register my callback. If there is already present, than the deviceReady event has already been called, and I just call it myself.

<body onload="onBodyLoad()">

Best Java Memory Analysis Tool

Submitted by prhodes on Thu, 07/15/2010 - 11:23

Just wanted to give some good words to the SAP memory analyzer.  It's free, and definitely worked for me where a lot of other tools didn't
