What to write in the "onDrop:" ?
by Sebastian Nozzi 13 Aug '09

13 Aug '09

Hello Seasiders, I am having trouble understanding how to make the Javascript (Scriptaculous) part talk to the Smalltalk one. Using Seaside 2.8. What I want to have are mouse-movable DIVs (which represend model objects) that remember their position the next time they are rendered. For that, I would like to know how to pass the coordinates (offset) from a dropped DIV back to the Smalltalk side and store that property in one model object. I've seen that SUElement provides something like this, but I'm clueless as to what to write in the #onDrop: part of my droppable to make the connection. It should extract the information via... Javascript? DOM? and send it back as a ajax-request to the server/smalltalk side... I am correct? The modified snippets would look like these: "Render the drop-container" html div script: (html droppable accept: 'myDraggableClass'; onDrop: "..." ); with:[ ... "Render the DIVs to be dragged inside container" myElements do:[:e | html div passenger: e; class: 'myDraggableClass'; script:(html draggable); with:'dragMe']. ...]. Any hints? Are there examples on the use of SUElement and co.? Thanks in advance! Sebastian.

Questions about double (or more) request
by Mariano Martinez Peck 12 Aug '09

12 Aug '09

Hi! I am trying to understand how seaside handle double or more, request. I started with the simpler example: WACounter, which has: renderContentOn: html Transcript show: 'renderContentOn'; cr. html heading: count. html anchor callback: [ self increase ]; with: '++'. html space. html anchor callback: [ self decrease ]; with: '--' increase Transcript show: 'increase'; cr. count := count + 1. (Delay forSeconds: 3) wait. Now, suppose the counter is in 0. I click one time on '++' and wait and I see in the transcipt: increase renderContentOn Ok, perfect. New session, 0 again. Now I click on '++' but before it finish, I click 3 times more (very quickly). I can see this in the transcipt: increase increase increase increase renderContentOn So, as I can see: 1) the callback (self increase in this case) is called for every click. 2) the renderContentOn isn't call until all of the self increase of that session finish. 3) when renderContentOn is called, the webpage shows the number 1 (which is correct instead of 4). Now the questions are: a) how does seaside can do that? every request has its own variables? I think this has to be with continuations but I want to be sure. b) which of all of the self increase is the one that is finally rendered? the first one? c) how can I handle the famous double commit? suppose now self increase does something in a relational database (like persisting an order or something like that) and I don't want it to get persisted twice or I don't want an error because of duplicated PK. Thanks for the help. I just want to understand how this is handle! best, Mariano

Problems with Seaside 2.9 libraries
by John Chludzinski 11 Aug '09

11 Aug '09

I'm porting code from 2.8 to 2.9. I have a chat app (currently model on CTChat) using Comet. I also have an app that uses SUTreeReport (using Scriptaculous). If I add the libraries in the following order, the app using SUTreeReport works: addLibrary: CTLibrary; addLibrary: MMAFileLibrary; addLibrary: MMALibrary; addLibrary: JQDevelopmentLibrary; addLibrary: PTDevelopmentLibrary; addLibrary: SUComponentLibrary; addLibrary: SUDevelopmentLibrary; If I add libraries in the following order my chat app works: addLibrary: PTDeploymentLibrary; addLibrary: CTLibrary; addLibrary: JQDeploymentLibrary; addLibrary: MMAFileLibrary; addLibrary: SUDeploymentLibrary; addLibrary: SUComponentLibrary; addLibrary: MMALibrary; It looks like PTDeploymentLibrary clashes with something else, likely JQDeploymentLibrary. ---John

Seaside + JQuery example page on port 9090?
by Thierry Thelliez 11 Aug '09

Having these examples on port 9090 is making access difficult when you are behind a firewall. Could they be moved to a regular port? Thierry

two inputs one updater
by Sebastian Sastre 11 Aug '09

11 Aug '09

Hey guys, anyone knows how to: - update 2 inputs - using one updater? having that: - there are other inputs in the same page - only one big (tag) form wrapping all When I saw the implementation of triggerFormElement: I've though two parameters can came serialized in the POST so I've tried this: updater callback:[:h| self renderThoseTwoInputsOn: h]; triggerFormElement: idInput1; triggerFormElement: idInput2; yourself. but with that I only get the model of input1 updated. As workaround I'm posting the whole form but is really not ideal. What could be interfering with the update of the second input? maybe the serialized value of the second input is not hitting its callback? fixable? hints? thanks, sebastian

Magma + Seaside (+Seaside28Jetsam?)
by Ramiro Diaz Trepat 10 Aug '09

10 Aug '09

Hi,I am trying to get a working image that includes Seaside and Magma. I am using the latest Pharo web as my start point. I have published a couple of Monticellos with the extension migrations from BlockContext to BlockClosure. After this, Magma seems to work fine in Pharo. But, to install the seaside modules, the wiki says that I must first install Seaside28Jetsam Which seems to break Seaside (2.8). This was surprising since the latest version seems to be very recent (7th of July). Any clues on how to get this stack working will be greatly appreciated. Cheers r.

Socket(Object)>>primitiveFailed
by Germán Arduino 09 Aug '09

09 Aug '09

Hi: I'm trying to start an image in the form "completepath/vmname completpath/imagename completpath/startupscript arg1" were arg1 is the a port number to start WAKom. As not worked headless I tried showing the main Squeak window and I get the subject error with not much more info. I researched the lists but not found nothing related. I'm using "Squeak 4.1.1beta2U.app" with a 3.10.2 image running on Mac OS X Server 10.5.5. I tried on a linux box with a unix vm and get the same error at socket level (Socket>>listenOn: / TcpListener>>pvtOldListenLoop:). Any help will be appreciated. Thanks. -- Germán S.

wikiserver 1.4.4 promo codes
by John M McIntosh 09 Aug '09

09 Aug '09

Apple approved WikiServer 1.4.4 for sale on the App store yesterday, as usual they have handed us another 50 USA promo codes, so if there are people on the list that would like one or two, please email me, not the list, a request. I note these are for USA itunes customers, but there are ways for people to create a new dummy itunes USA account with out supplying credit card information to redeem the promo code then install the app on your device for a month of free usage. Since we now support the ability to export the wiki data and run on a desktop version it's easy to preserve any data for later importing into a purchased version. -- = = = ======================================================================== John M.

Seaside + JQuery example page on port 9090?
by Torsten Bergmann 08 Aug '09

08 Aug '09

There are tools to access "non standard" ports if you are behind a closed (8080/80) firewall. But I agree with Thierry - ports like 9090 make life harder if you quickly want to show a (non local) seaside demo. So having all demos on a reliable server with standard port would make it more comfortable.
