[ANN] Rickshaw.js charting library for Seaside
by Esteban A. Maringolo 01 Oct '14

01 Oct '14

I just uploaded to SmalltalkHub an initial wrapper for the Rickshaw.js charting library (http://code.shutterstock.com/rickshaw/). As usual, you can load it with the following expression: Gofer it smalltalkhubUser: 'emaringolo' project: 'rickshaw'; package: 'ConfigurationOfRickshaw'; load. (Smalltalk at: #ConfigurationOfRickshaw) project development load: 'All' This will load all the packages, including a Seaside component installed at '/rickshaw' containing various examples. It is an initial version and my first package uploaded to SmalltalkHub, so bugs and and mistakes are expected :) Questions are welcome too. Regards, Esteban A. Maringolo

Checkbox and AJAX?
by Mariano Martinez Peck 08 Jul '14

08 Jul '14

Hi guys, I have this piece of seaside that renders a checkbox: renderCellFormContent: anObject on: html html form: [ html label:[ html checkbox submitOnClick; value: (self isSelected: anObject); callback: [ :value | self selectRow: anObject value: value ]]] That checkbox is actually one table cell of a row of a table (the first column) to select/unselect items. I would like to make this checkbox go with an AJAX request so that the whole page is not rendered and hence I loose scroll position etc.... So..what I need is that in the onClick of the checkbox I send an AJAX request. The checkbox of course should be updated and I also need to be able to continue executing the callback and the value. Any idea how can I do this in Seaside? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

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

Accessing current session in RestfulFilter
by Esteban A. Maringolo 01 Jun '14

01 Jun '14

The RESTful filter is part of the Component as a decorator of it, but if I try to access the current session dynamic variable it is not available. How do I do to retrieve the current session in the filter? Is it possible? Regards! Esteban A. Maringolo

Problem loading css in updateRoot:
by jtuchel＠objektfabrik.de 30 May '14

30 May '14

Hi, I tried adding a css file from a WAFileLibrary sublass to only one component, because it is really just needed on pages that use the WAComponent that refernences it. The reason is that if you use #selectorsToInclude on the file library, the css will be imported into every single page. It is a larger css file, and since our production server uses https, I'd like to avoid importing too much. So I implemented this: updateRoot: htmlRoot super updateRoot: htmlRoot. htmlRoot stylesheet beCss url: KontolinoFileLibrary / #buaDetailsCss. I either don't understand the purpose of updateRoot: completely or there is some problem with this approach: In IE 11 and Safari 7.0.4 as well as Firefox 29, the css link is not always in the head-section of the resulting page. But is there if I hit the Browser's reload button on the page. This is quite consistently so, but in maybe 3 out of 25 tries the css is also in the page when I navigate to it by call: or show: So far I only tried that locally with direct http access to the image (development machine), no front-end http server. Am I trying to do something at the wrong place - should I use another method for this? Is this a bug in Seaside? I have only tried in VA Smalltalk so far... For now, the css is back to #selectorsToInclude. But I would like to use a technique that allows me to only add js and css files and such on pages that include a certain Component, to reduce load and execution times of complex pages.

Welcome norizzk.com
by Johan Brichau 30 May '14

30 May '14

Hi all, Yesterday, a new web application built with Seaside in Pharo and deployed with GLASS in Gemstone/S was launched to the world: www.norizzk.com Norizzk.com is an innovative platform for risk-based test management. Watch the trailer on https://www.youtube.com/watch?v=MMqMwl6C-lk Once again, the use of Smalltalk, Pharo, Seaside and Gemstone has proven to be a competitive advantage in the development of a stunning innovative product. Some of you may well know the lead developer of this project, Veronica, who did her Phd as part of the RMoD team in Lille and the SOFT lab in Brussels. Over the past year, Veronica worked with Inceptive on this project and is now continuing the lead and development at the customer. The inceptive.be team wishes them good luck and we look forward to continue the development collaboration. http://jbrichau.github.io Johan

Generating an callback URL for third-party use
by Esteban A. Maringolo 28 May '14

28 May '14

I'm struggling to find a clean way of generating an url to be used for external reference from a javascript library/plugin, such as crossfilter or DataTables. E.g the constructor configuration object has a dataUrl parameter, which will be used by the plugin to retrieve the data. $('element').plugin({dataUrl: "..."}); I can generate the expression to retrieve it from anywhere, but what I want is to associate an url with a callback that will answer the data requested. Today I'm assigning results to a local variable using a predefined callback function, and then initializing my data dependent function assuming there is going to be data in that variable. Ej: html document addLoadScript: ( ((html jQuery getJson json: [ :json | self renderItemsOnJson: json ]; onSuccess: (JSStream on: 'myCallbackFunction(arguments[0]);') asFunction) asFunction assignTo: 'loadCrossfilterData')). html document addLoadScript: (JSStream on: 'loadCrossfilterData()'). I want some way to create a url callback in the way of: callbackUrl := html magicalCallbackRegister: [ :json | self renderItemsOnJson: json ]. "answers a url" JSStream on: '$(''#element'').plugin({dataUrl:"', callbackUrl, '"})'. which once rendered as JS would be: $('#element').plugin({dataUrl:"/app/_s=...&_k=...&n"}); I know this must be possible, because Seaside does it for all the callbacks, but I don't know how to create a simple callback and then get it's url to pass it around. I hope all I wrote is intelligible. Otherwise I can rephrase it in other unintelligible way. :) Esteban A. Maringolo

How did you solve the ajax & back browser button problem?
by Sabine Knöfel 28 May '14

28 May '14

Hi, my application does much with ajax calls and because of this, my browser history is nearly empty. There are, indepently from pharo and seaside, several solutions for this problem described in the web. But after looking around for a while I want to ask how did (or how would) you solve this problem within pharo and seaside? I want that my users can click the back button and go to the "page before". Can I solve this with Seaside-REST? Which is the best way?
