Can a decorator be associated to many owners?
by Joseph Blatter 01 Nov '06

01 Nov '06

i want just one aWAMyDecorator to be the decorator for various components. But AFAIK decorators are bound to an owner. so i was trying to attach a decorator (the same) to two components, one of these components (a select tag, the first one) has associated a live callback: aMyComponentOne>>renderContentOn: html html select list: #(1 2 3 4 5); selected: 2; labels: [:ea | ea printString ]; liveCallback: [:anIndex :h | self halt ]. aTestComponent>>renderContentOn: html aMyComponentOne addDecoration: aMyDecoration. html render: aMyComponentOne. aMyComponentTwo addDecoration: aMyDecoration. html render: aMyComponentTwo. When i select an item i get an "Error: Components not found while processing callbacks: aMyComponentOne" error message. however if i invert the calling order aTestComponent>>renderContentOn: html aMyComponentTwo addDecoration: aMyDecoration. html render: aMyComponentTwo. aMyComponentOne addDecoration: aMyDecoration. html render: aMyComponentOne. works fine, (?) so isn't clear for me why decorators are related to callback processing. cheers __________________________________________________ Correo Yahoo!

Anyone using Seaside & Paypal?
by Rick Flower 31 Oct '06

31 Oct '06

Just curious as I get further in writing my web-app in Seaside, whether or not anyone else here has implemented a paypal package that works in conjunction w/ Seaside & VW? I could take a stab at implementing one, but thought I'd ask first.. Thanks for any info you've got..

Space Breaking LiveCallback in IE
by Ron Teitelbaum 31 Oct '06

31 Oct '06

Hi All, I just found an error that was interesting so I thought I'd pass it along: This is just a test app, but it has a toggle anchor that shows different search forms. If a form has a table that has table data that only includes a space the live update fails in a strange way. By uncommenting the alerts on the #ajax method I saw the error: Reference to undefined entity 'nbsp' Which caused the form to render without any surrounding components. This works fine for Firefox. But I also noted that having an alert in the fireFox code causes the liveUpdate to not work at all. So only use the alerts for debugging IE only, and don't include TD spaces in your live updates. html text: ' ' does work. Ron Teitelbaum

WAEmailErrorPage missing?
by Nevin Pratt 31 Oct '06

31 Oct '06

I'm just starting to play with the latest Seaside on Squeak 3.8. I just noticed that there is no longer a configuration parameter for emailing the stack when an error occurs. This was previously provided by WAEmailErrorPage. Why was that functionality removed? Or am I just overlooking something? Nevin

Image Freezing
by Ron Teitelbaum 31 Oct '06

31 Oct '06

All, Ok after a little poking around I noticed: CTPusher >> startUp self shutDown. delay := Delay forSeconds: 15. process := SeasidePlatformSupport withName: 'ping' withLowestPriorityFork: [ [ self pingProcess ] repeat ] I've been working with Squeak for a long time now and never had the image freeze up on me before. The only thing I did differently was to load the Comet application. In the bug http://bugs.impara.de/view.php?id=4882 I noted that I was able to reproduce the error without starting seaside. The above code seemed like a good candidate, so I terminated the process. I was not able to get the image to freeze up after this. I tried changing the priority from 10 to 11 so that it would not run concurrently with idle process and it still had not frozen up on me. Does this process have to run at the same priority as idle? Is there a problem with a deadlock in the priority switching process of the vm? Ron Teitelbaum

RE: [Seaside] Space Breaking LiveCallback in IE
by Ron Teitelbaum 31 Oct '06

With the alert still loaded and the space error gone, there is no alert for MS IE 6.0. The form is replaced and the search button on both forms works fine. Is there some other way I can see the form replacement error. I'd hate to hit it later with something more complicated. Do I need to load an older version of IE to see it? Thanks for your help! Ron _____ From: Michel Bany [mailto:michel.bany@gmail.com] Sent: Tuesday, October 31, 2006 9:42 AM To: Ron(a)USMedRec.com Subject: Re: [Seaside] Space Breaking LiveCallback in IE Before fixing it with loading order I added your exception alert. MS IE 6.0 didn't catch the exception, I got no alert. That makes sense. You had two errors, (1) the nbsp error and (2) the form error. The alerts I suggested were supposed to demonstrate the form error. However, the nbsp error occurs first. Now that the nbsp error is fixed, try again the alerts and you should get them. Having the space in the table causes the updated code to show on the page, the problem is that it replaces the entire page with the update stream. All the other components disappear. With Seaside reloaded on top of SeasideAsync, "html space" is output as &nbsp which is invalid XML (valid XML is &#160). This causes an XML parsing error in the javascript and the javascrit assumes that the server has responded with a debug page. That's why the entire page is replaced. Good to hear that your problem is fixed. Cheers, Michel.

Nested forms - next solution in ShoreComponents
by Pavel Krivanek 31 Oct '06

31 Oct '06

ShoreComponents-3-pk.2.mcz can work again with nested forms. The solution is very similar to the solution in ShoreComponents-2.6 but it doesn't require parent references. The next little improvement is that ShoreComponents supporting html code is placed in the special component so applications that cannot use ShoreRootComponent subclass as the root component can use ShoreComponents too if they place this component somewhere. I think that it may be good idea to test this solution of nested forms properly and use it directly in Seaside. It helps to create more general and reusable components. -- Pavel

Access to the request GET fields in a WATask
by Sébastien Rocca-Serra 31 Oct '06

31 Oct '06

Hi, I have to respond to this kind of URL: http://some.server.com/seaside/myapp?login=foo&key=1234 I created MyTask, a subclass of WATask and chose it as root component for 'seaside/myapp'. My problem is that I can't access to the initial request fields (login & key). Note: self session currentRequest fields contains the usual _k and _s fields, but not my initial fields. Any suggestions? Thanks, Sebastien.

RE: [Seaside] Space Breaking LiveCallback in IE

Teach me to hit alt-s in an email! Sorry. It does appear to work just fine in IE as long as the space is not there. The rest of the code is here: renderSimpleSearchOn: html html form defaultAction: [self search]; with: [ html table id: 'searchTable'; with: [ html tableRow: [ html tableData: [html text: 'First Name: ']. html tableData: [html textInput value: 'Enter First Name']. ]. html tableRow: [ html tableData: [html text: 'Last Name: ']. html tableData: [html textInput value: 'Enter Last Name']. ]. ]. html submitButton id: 'findPerson'; callback: [self search]; text: 'Search'. ]. renderAdvancedSearchOn: html html form defaultAction: [self search]; with: [ html table id: 'searchTable'; with: [ html tableRow: [ html tableData: [html text: 'First Name: ']. html tableData: [html textInput value: 'Enter First Name']. ]. html tableRow: [ html tableData: [html text: 'Middle Name: ']. html tableData: [html textInput value: 'Enter Middle Name']. ]. html tableRow: [ html tableData: [html text: 'Last Name: ']. html tableData: [html textInput value: 'Enter Last Name']. ]. html tableRow: [ html tableData: [html text: 'Name Suffix: ']. html tableData: [html textInput value: 'Enter Name Suffix']. html tableData: [html text: '(Sr. Jr. III ...)']. ]. ]. html submitButton id: 'findPerson'; callback: [self search]; text: 'Search' ]. I wasn't aware that the last two alerts were causing the problem. Funny too cause those were the only ones I tried! Thanks for pointing that out!

If a form has a table that has table data that only includes a space the live update fails in a strange way. By uncommenting the alerts on the #ajax method I saw the error: >From your description, I understand that your callback generates a form, i.e. something like liveCallback: [:renderer | ... renderer form: [ ... ] ... ]. I believe this won't work with IE. The #ajax js, uses innerHTML to update the DOM and I believe that IE does not allow form tags in this case. But, maybe, you are trying something else.... This works fine for Firefox. But I also noted that having an alert in the fireFox code causes the liveUpdate to not work at all. As far as I can remember, I believe that only the last two alerts are specific to IE, i.e. the ones sending parseError. HTH Michel.
