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

Jquery submit loads page
by Norbert Hartl 06 Jun '13

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
by Robert Sirois 14 Sep '12

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

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

loading Seaside 3.0.6.3 in Pharo 1.4
by Esteban Lorenzano 01 Mar '12

01 Mar '12

Hi, I loaded last version of seaside into a pharo 1.4 image. Everything looks working fine, but there a couple of fixes: 1) KomLogger>>#attachTranscript self detachTheTranscript. ^(self streams detect: [:ea | ea isTranscriptStream] ifNone: [nil]) ifNil: [self addStream: TranscriptStream new] "TranscriptStream" is not anymore on pharo and should be replaced with ThreadSafeTranscript 2) String>>#withBlanksTrimmed is deprecated, and now it should use #trimBoth how can I proceed to apply this fixes into seaside (without breaking other platforms)? cheers, Esteban

ESUG SummerTalk - Fuel, binary object serializer
by Martin Dias 28 Feb '12

28 Feb '12

Hi folks. I am really happy to announce that ESUG is sponsoring me for Fuel development through the ESUG SummerTalk. I am Martin Dias, a student at Buenos Aires, Argentina. The idea behind this SummerTalk is to implement Fuel, a binary, fast and general-purpose object graph serializer in Pharo<http://www.pharo-project.org/>. It is based on VisualWorks' Parcels ideas. Actually, the project has already started since several months. Tristan Bourgois and I started with the project while doing an internship with RMoD, INRIA <http://rmod.lille.inria.fr/web/pier>. Since a couple of months, Mariano Martinez Peck <http://marianopeck.wordpress.com/> joined the team, and now he is the official mentor in the SummerTalk. ESUG website for SummertTalk: http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011 The website with all the necessary information is here: http://rmod.lille.inria.fr/web/pier/software/Fuel It even includes slides explaining the algorithm. In addition, a paper is in progress. For the moment, Fuel already provides the following features: - Fast pickle format. It is much faster to materialize than to serialize. - Correctly support class reshape (when the class of serialized objects has changed). - Serialize ANY kind of object. For the moment there is no object to our knowledge that we cannot serialize and materialize. - Be able to completely serialize classes and traits (not just a global name). - Support cycles and avoid duplicates in the graph. - Integration to Moose <http://www.moosetechnology.org/> with an extension to export and import their models. - Detection of globals: for example if you serialize Transcript, it is not duplicated and instead managed as a global reference. - Solve common problems like Set rehash. - Buffered writing: we use a buffered write stream for the serialization part (thanks Sven!). - No need of special support from the VM. - Try to have a good object oriented design. - Well tested (about 120 tests, for the moment). - Large set of benchmarks (even benchmarks for Moose extension). And of course, there are a lot features for the future. You can see some of them in the website and some in the issue tracker: http://code.google.com/p/fuel/issues/list We really appreciate all kind of feedback and comments. If you want to try it, check in the website how to do it. It is extremely easy. Once again, I want to thank a lot to ESUG for sponsoring the project. I plan to create a "news" section in the website with some RSS. I will keep you informed. Best regards, Martin

Image refresh
by Alexander Lazarević 13 Feb '12

13 Feb '12

Hi! I'm looking for a suggestion to do the following. I want to display an image that will be composed depending on user selection. All combinations are too numerous to be prerendered and just referenced in a CSS. So what would be a good way to force a reload/redisplay of that image? Thanks, Alex

Re: Re: [Seaside] How do I use JQuery with Javascript variable

Thanks Johan for your response. I saw my omission of the code snippet "addLoadscript html document:" before your reply. I put also indicated halts but they were not reached during the execution. Another question I have is this: the original code runs entirely in Javascript on the client. There is no way to do the same in Seaside with JQuery? > > Francisco, > > Wait... now I see that you are just generating the script but you are not attaching it anywhere.

Thanks Johan for your answer. See my code below: renderContentOn: html | checkedValue | (html jQuery: #testButton) onClick: (html jQuery ajax callback: [:val | checkedValue := val] value: (JSStream on: '$(''[name="someRadioGroup"]:radio:checked").val()'); onComplete: ((html jQuery: #result) load html: [:renderer | renderer html: 'The radio element with value <tt>' , checkedValue , '</tt> is checked.'])). html form: [html div: [html label for: #radioYes; with: 'What is your answer?'. html radioGroup: [:group | html radioButton id: #radioYes; group: group; name: #someRadioGroup; value: #yes; selected: true; with: 'Yes'. html radioButton id: #radioNo; group: group; name: #someRadioGroup; value: #no; with: 'No'. html radioButton id: #radioMaybe; group: group; name: #someRadioGroup; value: #maybe; with: 'Maybe'. html radioButton id: #radioConfused; group: group; name: #someRadioGroup; value: #confused; with: 'I dunno']]. html div: [html button type: #button; id: #testButton; class: #green90x24; with: 'Which?']. html div id: #result] Unfortunately the code did not work.
