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

Hi - Following these instructions you can make Comanche serve static files from a local directory while also handling Seaside requests: http://samadhiweb.com/blog/2011.07.10.seaside.comanche.staticfiles.html Is there a way to do the same with Zinc and the ZnStaticFileServerDelegate ? Thanks Paul

jQuery Ajax: do something before and after
by jtuchel 25 Mar '13

25 Mar '13

Hi, I am trying to do something pretty simple (I thought): I want to show some wait dialog or replace a submit button with a spinning wheel and the text 'please wait' until the ajax has finished. For this I did something like this in my code s submitButton onClick: ( s jQuery ajax onBeforeSend: (((s jQuery class: 'submit') hide)); callback: [self doSomething]; onComplete: ((s jQuery class: 'submit') show)); with: 'Click here'. I tried to open a jQuery dialog in the beforeSend and closing it in complete, but this either doesnt work at all or only in one of FF and Chrome, but never in both. How do people solve this "easy" task?

You need better descriptions for behavior, relationships, validation. - Generate web components by introspection. - Use a hexagonal architecture. - Persistence is an implementation detail, to be decided on ALAP - In the component model of Seaside a component has children; the child does not have an explicit parent (as there might be more than one). The child uses announcements to inform its parent. - In development, break up the css into many methods - Refactor - The reflective capabilities of Smalltalk allow fairly large architectural changes to be made with little effort. Learn how to manipulate your project's source code - Development is done in a MOOSE image, so you can visualize the code quality over time. - Did I tell you to refactor? Stephan Eggermont

Hi, I need an example how to use JQSelectMenu>>bgImage: and JQSelectMenu>>icons: The JQSelectMenu is part of JQWidgetBox. It works fine but I did not succeed in adding Icons/bg images. A code example from someone who is using it would help me Sabine -- View this message in context: http://forum.world.st/JQSelectMenu-bgImage-tp4666503.html Sent from the Seaside General mailing list archive at Nabble.com.
