Seaside Book, Chapter 17, File Library
by blake 28 Apr '12

28 Apr '12

I'm looking at chapter 17, on the file library, and when I get to the practical example in 17.4 I don't see how it works. Clearly, you're supposed to piggy-back the file library on to the counter component, but there's no explanation of how. The only code shown is: WAFileLibrary subclass: #CounterLibrary instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Test' And this is followed by two screen shots which show a visual representation of...looks like a file picker (HTML input file type), and some buttons. But I don't see where they come from. FileLibrary descends from WAObject, not WAComponent (sensibly), so it can't come from the WAFileLibrary itself. What am I missing? ===Blake===

Session method in the Object class
by dtrussardi＠tiscali.it 26 Apr '12

26 Apr '12

Ciao, i have some Object subclass for define my application database ( table1 table2 ecc. .... ) and relative management methods. Sometime in the relative method i need to access to the request session . For now i use the code : session := WACurrentRequestContext value session. I'm tempted to define the session method in the Object class, but i found session and application method in the WAObject class. My question is : i can define my database class how WAObject subclass ( to inherit session method ) or it's better to avoid such definition ? Thank for any consideration. Dario

Not directly, but you can do html fileUpload attributeAt: 'multiple' put: true But I haven't yet checked out whether that works correctly with callbacks. I created an issue for this [1]. My understanding though is that browser support is spotty at best. You may want to look into a JavaScript solution. > My users will be > uploading a LOT of files. You may want to do load testing in this area. This hasn't historically been a strength.

Is it a structural issue or something that I could maybe add? Javascript-wise, there is a JQuery component that does multiple uploads, here: http://blueimp.github.com/jQuery-File-Upload/ --is it feasible to hook that up to a Seaside app? ------------------------------ _______________________________________________ seaside mailing list seaside(a)lists.squeakfoundation.org http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside End of seaside Digest, Vol 112, Issue 33 ****************************************

file upload -- multiple?
by blake 22 Apr '12

22 Apr '12

Hello, Seasiders, I'm trying to work out a utility that allows my users to upload files (text) and reports back certain information about those files. First, Seaside is definitely one of the coolest, simplest frameworks for this, I think. Second, is the "multiple" feature available? My users will be uploading a LOT of files. ===Blake===

Using Monticello
by blake 19 Apr '12

19 Apr '12

Separate of Seaside, I decided to try to figure out how Monticello is supposed to work so I could then report back on what's wrong in the Seaside Dev book and I came across this video from Ramon Leon on how to use Monticello. http://onsmalltalk.com/screencast-how-to-package-smalltalk-code-with-montic… ...and I get hung up in the exact same place! 1. I created a category called "AAA" and made a class called "AAA1" with a single method "someMethod". 2. I opened the Monticello browser. 3. I added the package "AAA" to the Monticello browser. 4. I browsed the package "AAA" from the Monticello browser, which was reassuring. 5. I added a repository, pointing to a local directory. 6. I clicked on "Add to package..." (argh, still seems like it should be "add package to...") 7. The "AAA" package is not there. Now, I subsequently checked "AAA" in the Package pane and the local dir in the repository pane and pressed "Save". That seemed to work! So I removed the class from the system browser, then went back to the repository, clicked Open, saw the "AAA" category, clicked that and the mcz file name--and it loaded just fine. But I'm worried because step 6 doesn't make any sense to me and doesn't seem to work for me like it does elsewhere. ====Blake===

Call application with parameter
by dtrussardi＠tiscali.it 19 Apr '12

19 Apr '12

Ciao, i have a WAComponent subclass DisplayArticoli register as 'articoliOnLine' . The application implement some traditional anchor and some AJAX element. The goal of this application is rendering all the items of one specific shop. I' have some shops: shopA, shopB, shopC . When from browser i request it i'm interested to pass a parameter with a specific shop name. For example: http://www.test.com:9090/articoliOnLine?_shop=shopA So when a new session is open a specific shop reference is set. What is the best implementation to do it ? I do some test: for now i change the WASession handleFiltered: aRequestContext. If in the aRequestContext request fields i found the _shop parameter i set the shop reference in the WASession shop instance to the relative value. In DisplayArticoli renderContentOn: method i had: html document addLoadScript: (html jQuery ajaxSetup onError: (html javascript alert: 'The session has expired. '; goto: 'http://www.test.com:9090/articoliOnLine?_shop=shopA' )) this redirect the browser when a ajax request trigger a error ( after a expired session for example ) and work fine. The problem is relative to the anchor event when the session is expired because the default expiredRegistryKey "The session key has expired, redirect the request to the home directory preserving the path as good as possible." lose the path _shop=shopA parameter. Is my test in the right direction or i wrong ? Any considerations is welcome. Thank, Dario

Dynamic Web Development with Seaside, Monticello
by blake 18 Apr '12

18 Apr '12

>From the book: ------------------ http://book.seaside.st/book/getting-started/pharo/monticello Make sure this new repository is highlighted and select add to package... from the repository pane context menu. Select the WebCounter package from the resulting menu. ----------------- Curiously, the WebCounter package doesn't appear. It's been a while since I've used Monticello, but I do have a category, WebCounter, I've been following along with the book to this point. Created the WebCounter app. I've run it. When I got to this point, the WebCounter didn't appear where it should. I "save and quit"-ed out of Smalltalk and tried again, still not there. So I went back to the Browser and WebCounter is still there but it's empty. I say to remove empty categories and, sure enough it removes WebBrowser. Most bizarre. I can see all the code in my changes file. I can also see removeSelector calls at the end.

state in request handler
by Norbert Hartl 17 Apr '12

17 Apr '12

I'm using a seaside rest handler and I was wondering today how concurrency issues are handeld there. The request handler is a component that is always the same object for incoming requests. I need to set a heavy weight component at incoming request and I want to have it accessible until the response is send. Where is the be place to put such kind of state? Starting to add an instance variable in the request handler I had the impression this is a bad thing to do. And then I was wondering how multiple threads are handled in seaside. Or better what operation can be considered thread safe and where I need to put extra effort to protect intermediate state while processing. My component needs to be initialized by the incoming request context and is accessed multiple times until process has finished. Any hints? Norbert

Problems with WANoDuplicateUuidsTest and Magritte image
by Martin Sandiford 16 Apr '12

16 Apr '12

Hi Folks, If I download the latest Magritte 2 image from here: http://jenkins.lukas-renggli.ch/view/Pipeline/job/Magritte%202/ and run the WANoDuplicateUuidsTest, it runs forever. Well at least for an hour on my Mac before I gave up :) This doesn't happen with the Seaside 3.0.7 one-click or image, so it seems like something is happening while loading Magritte. Is this a known issue? Cheers, Martin P.S. Thanks for the awesome framework that Seaside is!
