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

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

slow picture loading
by Tudor Girba 27 Nov '12

Hi, I am working on a pier page, and I have a couple of images in it that seem to be slow to load, although they are served through apache. It is true that the images are slightly large (~230K), but still I think they appear too slow. The example is here: http://www.humane-assessment.com/ Anyone has any idea of why this would happen? Cheers, Doru -- www.tudorgirba.com "Live like you mean it."

Re: How to migrate a VW-Application to Seaside
by Stephan Eggermont 26 Nov '12

Hi Josef Without knowing more about your specific situation, I would start adding some small reporting/presentation part to your application. This would allow you to get to know Seaside in a way that can directly add value to your system. There are several things to investigate and try out before committing to port the whole system to the web: - SeaBreeze - Amber - jQuery with jQuery-Mobile and Twitter bootstrap If you provide some more info on your goals and needs, we can be more specific. (whole application vs reporting only, mobile needs, graphical performance needed, amount of data moved around etc.) Stephan

HTML5 and RenderLoopContinuation
by Tobias Pape 26 Nov '12

26 Nov '12

Hi I just played with Seaside and HTML5, however, the resulting html is not HTML5 compatible. The validator says Line 2, Column 249: Bad value Content-Script-Type for attribute http-equiv on element meta. which is the result of WARenderLoopContinuation>>updateRoot: "…" anHtmlRoot meta contentScriptType: WAMimeType textJavascript. anHtmlRoot htmlAttributes at: 'xmlns' put: 'http://www.w3.org/1999/xhtml'; at: 'xml:lang' put: 'en'; at: 'lang' put: 'en'. "…" The content script type is incorrect as of HTML5. (see answer here: http://stackoverflow.com/questions/6320084/why-is-meta-http-equiv-content-s… ). Also, 'xml:lang' is accepted for compatibility only, and 'xmlns' is incorrect for HTML5 too (while silently ignored). Long story short, can we optionalize this part? I can work around the xml:lang and xmlns-attributes in a subsequent #updateRoot: but I cannot undo the content script type without editing WARenderLoopContinuation>>updateRoot: If you want to, I can try to come up with something.
