Application level state
by Bernhard Pieber 22 Jul '17

22 Jul '17

Hi all! I have subclassed WASession to add my own session specific state. I would like to do the same for WAApplication. However, I have read in the mailing list that WAApplication is not supposed to be subclassed. I tried using preferenceAt:put: to set my root model object. However, I get WAAttribute not found. This feature seems to be for configuration purposes, mostly simple data types and classes. So far I used the singleton pattern, a class variable in my root object model class. But now I would like to register the same component class twice using different context paths. What is the most idiomatic way to achieve this in Seaside? Cheers, Bernhard

Disabling Chrome auto-retry feature
by Esteban A. Maringolo 22 Jul '17

22 Jul '17

Hi all, This might be a slight off-topic question, but there is a behavior that nags me, and it is Chrome automatically retrying a request. E.g. I get an error during development, so I decide to debug it (using the "debug" link in the page walkback), in the middle of the debugging I decide to close the debugger and fix it in the code browser or any other tool. This produces an ERR_EMPTY_RESPONSE on Chrome, and it re-attemps the last request, causing the walkback to fire again. Is there a way to disable this? Esteban A. Maringolo

How can I make this kind of redirect in Seaside?
by Mariano Martinez Peck 20 Jul '17

20 Jul '17

Hi guys, Ley's say I have a root component registered in /registration which takes care of user registration. Inside a callback of a button ('Register') I want to redirect to /reps (my real app prefix) which is associated to a different root task which renders the welcome/login window from which you enter to the app. What I want is to "auto-login" after register. So I need to make a redirect from /registration to /reps but auto-getting a session for that root task etc. I guess the way to do this is to simulate getting a session and make the redirect to /reps_s=... Any ideas? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Hierarchy of WAHtmlErrorHandlers
by jtuchel＠objektfabrik.de 17 Jul '17

17 Jul '17

Dear Seasiders I'd like to register a special HTM Error Handler for some Exceptions and one for all others. I've seen there is a class Method #exceptionSelector in WAErrorHandler, where you can define the Exceptions that the handler wants to handle. Of course things are not so easy, because I want one handler for all Errors and one for my special exception type, which, of course, is a subtype of Error. Ho do I either * Specify an order in which the handlers are tested whether they handle: an exception? or * Specifiy an ExceptionSet that includes Error and all its children, but not my special type? Any ideas?

How to handle errors with a page that can go back
by jtuchel＠objektfabrik.de 17 Jul '17

17 Jul '17

Hi there, we've been using a WAHtmlErrorHandler for quite a while in our application, but there are some limitations to that appraoch: * If an error happens in a subcomponent, the HTML Error handler will only be displayed in place of the failing component, not as a page of its own. This is irritating for quite a few users, some even don't realize an error occured and contniue clicking and stuff... * I haven't found a way to allow the user to go back to the last page and redo their changes Let me give you an example of what I'd like to achieve: 1. A user submits a form and thus a callback is called on the server 2. The callback handling code runs into a resumable exception 3. We display a full page saying: "Hey, this and that is wrong, you better go back and change your input" (Unfortunately, the situations I am speaking about cannot be validated before the user submits - think of it as an optimistic locking failure) 4. This error page offers a "I want to go back and be a good user and correct my input" link or button. It is a root component, coverng the whole page under all circumstances 5. The callback of that link does resume the exception, maybe clear up some data and go back to the component the user came from Has anybody done this? Is it described somewhere? Thanks, Joachim -- ----------------------------------------------------------------------- Objektfabrik Joachim Tuchel mailto:jtuchel@objektfabrik.de Fliederweg 1 http://www.objektfabrik.de D-71640 Ludwigsburg http://joachimtuchel.wordpress.com Telefon: +49 7141 56 10 86 0 Fax: +49 7141 56 10 86 1

Need some table help
by Donald MacQueen 14 Jul '17

14 Jul '17

I am a relative Seaside newbie. I am trying to get up to speed by writing a small app to support our football club. I have a table of game data. Each row has game# time homeTeam awayTeam currentPick What i want to do is add a combo box as the sixth element in the table row which would have two selections: the homeTeam and the awayTeam. After selecting a pick, I want to update the row to show the new value for aWvPick currentPick, the fifth element. I have googled my brains out looking for an example and have grepped the last 3 years of the archives, but no joy so far. My table looks like this: html tableRow: [ html tableData: aWvPick gameNumber. html tableData: aWvPick time. html tableData: aWvPick home. html tableData: aWvPick away. html tableData: aWvPick currentPick"show the current pick here" "want to put combo box here"].

Is new #maximumAbsoluteAge optional?
by Mariano Martinez Peck 13 Jul '17

13 Jul '17

Hi, I understand the reason behind #maximumRelativeAge as I read it here [1]. However, if I understand correctly, it can happen at any request that my session is kicked out. That request could have been in the middle of an important work etc... So...let's say I want to disable this #maximumAbsoluteAge, how can I do it? remove the key? set a nil? BTW, is there another workaround to solve my main concern? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
