so i tail -f /var/log/messages and find these few errors after launching the app:

When I look at my disk usage, the only thing that scares me is that the root is almost full. Everywhere else is looking good. so where is the saved data stored?

I got the RSS app installed on the emulator and it worked fine. Then I added a feed and this worked also.

But after that, I cannot start the app anymore. It loads, then it shows some notifications about new entries and then freezes. Even the menu does not work anymore.

Deleting and reinstalling did not help. I guess, the config of the app is now messed up.

But how does one delete configs on webOS? In the old PalmOS, deleting an app deleted everything, AFAIR.

I don't know if I'm the only one in this case, but I happen to be stuck on page 70, when adding the feedList : apparently the problem comes from

Or at least, that's what I assumed since pushing a scene right before this line works, and pushing it right after just leaves me with the sdk generated text "find me in views..." from feedList-scene.html
Any ideas on what I could be doing wrong ? Or how I could use ssh on the emulator (on a Mac) since I can't seem to get that working either ...

Thanks a lot :-D

you need the most recent version of the book (that has the full source at the end) because the chapter does not include the source for the processFeed function. Just cut/paste that function into the feedList-assistant.js to solve the problem.

I tried that but it really won't work ... I added a Mojo.log at the top of the function, but apparently it doesn't even reach that part ... There's gotta be something I'm missing ... Is someting like "FeedListAssistant.prototype.processFeed = function(transport,index)", followed by the code from Appendix A okay ?

Thanks in advance :-)

I will also post what files I had to change and what I changed to make the app work as I cannot directly post the source.

Finally, if someone who can post files please grab it from my server above and post it here to the forum since the url is ugly as posted.

Thanks!

Where can we get a copy of the correct source code. I would like to check it against the code from the book, to see why my app isn't displaying anything?

I cannot post the source since the book is copyrighted. However, I am working on an app that is based off of that source and I will post that code. Also if you PM me a section of code you have in question or a file you would like to check. I will see what I can do for you.

PM me and I will reply with my cleaned processFeed function. I would PM you but I don't have 15 posts yet

Neither do I ^^
But I just updated my profile and put my e-mail adress as my Treo model (not the smartest thing to do, I know, but I really really want to solve this !)
Could you please email it to me ? Also, sorry everyone to the almost pm-like conversation going on here

the ipk file was posted earlier in this thread. if you install it on your phone or on the enulator, you will then have access to the full source. or, if you can find a windows port of the linux "ar" command (i have a tool installed on my computer called MKS Toolkit, that is a slew of unix commands and functions ported to windows), you can unpack the file and access the source in data.tar.gz using winzip.

Yeah, I haven't been able to get the same results regarding the News app. I guess that's why they call it a 'rough cuts' version.

Hi everyone,

I started the process for developing for the pre a few days ago and have been following along with the o'riley book creating the News Reader application. However, like a lot of people, I seem to be having trouble getting past section 3.4 on lists, as it appears my news reader won't process the feeds. So I have two questions:

How did some of you get past the ProcessFeed() problem? I tried to steal the function from the appendix, and paste it in the appropriate assistant, but no luck so far. What was your intermediate solution?

Second I feel I could get around this problem myself if I was able to properly debug the program or at least create console messages that I could use to monitor the progress of the application. Can you tell me if I'm doing something wrong and what I need to do to correct it.

- appinfo.json has "loglevel": "99"
- Mojo.Log.info ("Code made it to here"); has been placed in the setup function of the feedlist assistant. (Which should be the first thing called after the stage assistant and I can see that feedList-scene does load)
- I have ssh'd into the emulator and am monitoring /var/log/messages
- All of my work has been done in the emulator.

Thanks for any help!
Jack

If you use Mojo.Log.error("Code made it here") it will always be displayed, regardless if your running in debug mode.

I spent some time tonight and have this working.

I know its not the best solution because thats what the code from the book is trying to do. I'm trying to keep it simple and follow the patterns they've already talked about.

copy the processFeed method from the code from the book (you can get it on safari online, appendix A
add it to the bottom of feedList-assistant.js
Change the definition to:
FeedListAssistant.prototype.processFeed = function(transport, index) {
change the comma at the end to a semicolon
add the following to stage-assistant
var unReadFormatting = "unReadStyle"; // Prepended to story titles when unread
var errorNone = "0"; // No error, success
var invalidFeedError = "1"; // Not RSS2, RDF (RSS1), or ATOM
var unreadStory = "unReadStyle";
change any references to News.unreadStory to just unreadStory, same for any of the other globals
change this.feedlist references to feedList (notice the capital L)
change the invocation to
feedError = this.processFeed(transport, curFeedIndex);

hopefully i didn't forget anything .. i didn't have this under git so i can't go back and check all the changes.. i also had to fix a bunch of other stuff just to get to that point.. like pushing feedList instead of storyList.. etc..

good luck

Cool, but do you have the actual project files?

This .ipk works great for me also, except for the feed images, which someone pointed out previously.

Thanks sevensoft, i looked around for the ProcessFeed in the Appendix of the unpublished book... haha. I really appreciate you taking time to write down those notes, as I hit a wall on a page in the 70's.

I did see a comment about Mojo.log, anyone know the full syntax (does it support info, warn, and error type levels)?
