debugging javascript within browsers is hard when the browser show the response on a single line
by Nick Ager 05 Jul '14

05 Jul '14

Hi, I wonder if other people suffer from the same problem when debugging javascript: Seaside's response is viewed by browsers as a string without line-breaks. Normally this isn't a problem as the browser "pretty-prints" the output when inspecting the html. However when debugging javascript, either inline or within a file-library the script debugger (I'm currently using Mac Safari) shows the output as a single line - which makes it impossible to interpret any javascript generated errors ("syntax error: line 1"!!) or to set meaningful breakpoints. I've discovered that calling #withInternetLineEndings on the file-library string results in browsers interpreting the line-endings as expected. Locally when I'm debugging I've created a class derived from WAHtmlDocument, which overrides #nextPutAll: WAHtmlDocumentWithInternetLineEndings>>#nextPutAll: aString super nextPutAll: aString withInternetLineEndings and I modify WAFileLibrary>>#handle: modifying the WAResponse>>#document: to: document: ((self documentForFile: fileName) withInternetLineEndings) Is there a better solution? Are there easier workarounds, browser settings etc. I created an issue for this problem: http://code.google.com/p/seaside/issues/detail?id=675 Though if there are easy workaround that I've missed, I'd be delighted to close the issue. Thanks Nick

Maybe I'm just too tired to get it straight. I have html form with: [ html submitButton onClick: (html jQuery ajax serializeForm ); with: 'foo' ] and if I click the button I get the ajax request and afterwards the page is loaded. What could I've forgotten? thanks, Norbert

JQGrid Events

How do I add an event to my grid? There's a list here: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:events. There doesn't seem to be an easy way to associate a callback with a cell / row like WATableReport. RS

Twitter Bootstrap and Magritte
by Nick Ager 29 May '12

29 May '12

Hi, Based on the new file library (see previous mail) I've started work on a Twitter Bootstrap Magritte form renderer [1]. The repository includes the Twitter Bootstrap libraries, Twitter Bootstrap Magritte form and component renderers and a configurable Magritte form rendering example. If you want to give it a spin, you'll need the latest Seaside and Magritte 3 code, as well as the code from the repository. I've put the sample up on seasidehosting - http://twitterbootstrap.seasidehosting.st/ Cheers Nick [1] http://ss3.gemstone.com/ss/TwitterBootstrap

answer: and jQuery
by Malte Grunwald 22 May '12

22 May '12

Hello everybody. My problem: I am working with a JQDialog and when the "okay" button is clicked, I want to use a /callback:/ and /answer:/ to get back to the /go /method in my Task class. Example: /renderOptionsOn: html id: anIdString width: anInteger (html div) id: anIdString; script: (((html jQuery id: anIdString) dialog) title: 'test'; autoOpen: false; modal: true; width: anInteger; height: 'auto'; resizable: false; addButton: 'Okay' do: (html jQuery ajax script: [:s | s << (s jQuery id: anIdString , 'form') serialize; << (s jQuery id: #Settings) dialog close; << (s jQuery ajax callback: [self answer: self something])]); addButton: (self textAt: #CancelTx) do: html jQuery new dialog close); with: [self renderInputsOn: html commands: self settings id: anIdString,'test']/ I read a comment of Lukas Renggli from 2010, it says it is not possible to /answer: /from jQuery is this still up to date? Does anyone have an idea how I can solve the problem? Thank you! Regards

Handling expired Session in Seaside 3.0
by Udo Schneider 13 Apr '12

13 Apr '12

All, if this is just an RTFM question I'm happy to read on my own ... however I'm searching for a solution to handle expired sessions in Seaside 3.0. My goal is to either display a specific component when a request for an expired session is recieved or to be able to find out if a request was for an expired session in my initial component. Any pointers? CU, Udo

Cloudfork SSO - url generation
by Francois Stephany 06 Apr '12

06 Apr '12

I'm playing with Cloudfork SSO to manipulate objects stored on S3. Is there a way to generate a temporary url for an object stored in a private bucket ? A bit like the url_for method in the Ruby library (https://github.com/marcel/aws-s3): S3Object.url_for('beluga_baby.jpg', 'marcel', :expires_in => 60 * 3) If I understand correctly, it generates a link with a queryString that looks like: "AWSAccessKeyId=#{access_key_id}&Expires=#{expires}&Signature=#{encoded_canonical}" Is there something like this in Cloudfork ? Cheers, Francois

[GSoC] Call for students
by Janko Mivšek 28 Mar '12

28 Mar '12

Dear Students, Now it is your turn! You will have to register in our website first [1], put there some information, show interest for the projects and contact the project mentors. After the registration step you will get all the mentors information in order to contact them. By pressing the button on the project, you will show your interest. This is not something formal yet. Of course you can propose your own project too. In this case write a proposal in a format other projects have and send it to admins (see the email on the bottom). Our mentors will vote for the most interesting projects and in the middle of the voting Google will tell us, how many projects will actually be funded. Voting will happen in April, with final results expected at the end of April. At that time you will finally know if you are accepted or not. Of course, there can be many students interested per project. This means that interest for this project is high, but on the other side a chance that you will be chosen is lower. It is up to you to convince a mentor that you are the best! Note also that the Ideas page is deprecated. On ideas page just the project ideas were collected. Now, we are preparing the real projects. So, please from now on always refer to this link for the projects: http://gsoc2012.esug.org/projects So, the initial steps are: 1. Register on our special Smalltalk GSoC website (with your Google account!): http://gsoc2012.esug.org/admin?view=loginGoogle 2. Edit your profile to get some more contact information for mentors to let you know, 3. Fulfill your brief Biography page (see Biography tab on profile), 4. Go to Projects page, choose up to three projects and click there 'I'm interested' button, 5. Contact and discuss with project mentors about your interest. Subscribe also to a special mailing list [2] where we will help you with further steps. Deadline: as soon as possible, because the deadline to register on official GSoC website [3] is 6.April, which is, well, soon! But about that later... Finally, we will really appreciate if you can help us to distribute this call for students. One of our goals is to increase the Smalltalk community. Those who have access to universities can distribute this among the students.

Best-practices/ architectural patters for business apps
by Stefan Krecher 27 Mar '12

27 Mar '12

Hi, i'd like to know if there are some best-practices/ patterns for seaside application architectures. I've been working in JEE Projects in the last approx 10 years - and there we've got a lot architectural best-practices. Is there some kind of MVC-Framework like Spring etc in the Java-World? How are Transactions handled? Do we have ejb-like components like stateless or stateful session beans? Or should this not be a seaside-specific question? regards, Stefan
