Any code to share for a "remember me" functionality on logins? Is there a common pattern on how to do it? Thx T.

Re: [Seaside] ZnUnknownHttpVersion

It's working on a seaside server, but not on a RestServer.This code should show you the problem. | server |server := ZnServer startOn: 1700 .server delegate: (ZnRestServerDelegate new uriSpace: (ZnCallHierarchyRestUriSpace new rootClass: ZnExampleSumRestCall;yourself); yourself). (ZnClient new) get: 'http://localhost:1700/appName?action=&firstParameter=["Value"]&secondParameter=["Value"]&lastParameter={ "Key":["firstValue","secondValue"]}' Regards.

Hi sven,Thank you for your response. The problem is that the request is not even sent from the Client to the Server. Try to do this in a Workspace to get my error, a server must be running on the given port : ZnClient get: 'http://localhost:8080/appName?action=&firstParameter=["Value"]&secondParameter=["Value"]&lastParameter={ "Key":["firstValue","secondValue"]}

Changing subcomponts after AJAX call
by Esteban A. Maringolo 06 Mar '14

06 Mar '14

Hi, I'm refactoring the components in my seaside application in order to reuse some parts of them. Until now, everything was a single component, and the selector was a regular form, with an AJAX call to render the details of the selection in a div working as a container. Something like... ... html button bePush; onClick: (html jQuery ajax serializeForm; onComplete: ((html jQuery id: contentId) load html: [ :h | self renderDetailsOn: h ])); One of the things I'm trying to achieve is to change a to "master-detail" implementation, having the master as a general selector component and detail as an specific component for the selection. My questions is how this should be performed in the context of an ajax call. In normal Seaside flow I can have a container component and call the detail with #call:/#show:, but I have no idea of how this should be done in this context. Is it safe to have something like the following? renderDetailsOn: html html render: (MyDetailsComponent on: self selection) What if I need to call/show from the detail component? won't it break backtracking, it's not registered? Thanks in advance. -- Esteban

ZnUnknownHttpVersion
by lanvin.kevin＠laposte.net 06 Mar '14

Sorry for multiple copies. Hello I am using a REST API in my web application and I have a problem with the http version. when I do this kind of request, everything is ok : localhost:8080/appName?action=&firstParameter=["Value"]&secondParameter=["Value"]&lastParameter={} Parameters are JSON strings. Now if I just change the last parameter as following, the ZnUnknownHttpVersion error is raised. localhost:8080/appName?action=&firstParameter=["Value"]&secondParameter=["Value"]&lastParameter={ "Key":["firstValue","secondValue"]} Every special character is converted to %.. excepting ':' . Thank you

Fwd: MAStringReader and nil
by Otto Behrens 06 Mar '14

06 Mar '14

I apologise in advance if this cross post bothers you, but I'm not sure if people are looking at the other list where I posted. We will appreciate your help if you know something in this area of Magritte-Seaside. ---------- Forwarded message ---------- From: Otto Behrens <otto(a)finworks.biz> Date: Thu, Mar 6, 2014 at 12:38 PM Subject: MAStringReader and nil To: "Magritte, Pier and Related Tools ..." <smallwiki(a)iam.unibe.ch> Hi, We'd like some help with how nil / undefined is handled in Magritte, and specifically a MAStringDescription. The method MAStringReader >> read:description: overrides the default behaviour to return nil. Is a nil in Magritte seen as a "unpopulated" token? Our problem more specifically is this: We start with an object containing an string in an instance variable. We use a MAStringDescription for this instance variable. We use the magritte-seaside binding to edit this field on the UI. If the user does not capture text in the text input, an empty string is "written". The method on MAStringReader mentioned above intercepts this and returns nil, so nil is written back to our domain object, where we started off with an empty string. We do not want nils to be written into our domain object where we initialized it with an empty string. How do we fix this? Is there a hook where we should be specifying this? Or is there a fundamental way of working with Magritte-Seaside where it will write nils and we have to manage that on our domain object? Thanks for your help. Otto

Javascript calls through jQuery
by Esteban A. Maringolo 04 Mar '14

04 Mar '14

Is there a way I can perform an AJAX call to get a JSON response and pass it to a JavaScript function? Now I'm gluing everying externally by means of a JS file, but the AJAX calls are outside of the Seaside session (REST Filter), and I'd like to get everything in the same session. Thanks in advance, Esteban A. Maringolo
