[VW7.8NC] - How to display a News ticker on the bottom of a screen
by Dobbelstein, R. 17 Oct '11

17 Oct '11

Hi, I am new to this group and new to Seaside. I am trying to implement a kind of Slideshow in which the upper part of the screen displays several "slides" sequentially whereby the contents is dynamic. The lower part (consisting of one line of text) should display a News ticker scrolling from right to left and it should continue to do so even when the upper half of the screen changes. The source for the news ticker woould be the headlines of an RSS-feed. Any ideas how I can accomplish this? Code snippets or examples are very much appriated.

jquery serialization question
by Larry White 16 Oct '11

16 Oct '11

Hi, I'm having some strange problem with Jquery/Seaside. I'm trying to serialize a form containing a single testArea when the submit button is clicked. I have an onClick handler for the submit button that does this: (html jQuery ajax serializeForm onSuccess: (html jQuery ajax script: [ :s | s add: ((html jQuery: #postStatusTextArea) value: ''). s add: ((html jQuery: #activityStream) prepend: (CBActivityComponent post: self session user posts first)) ]) ); If I execute this by clicking the button the callback for the textArea gets invoked twice most of the time (though not every time). I tried wrapping the same logic inside a block instead of parens like so: [html jQuery ajax serializeForm onSuccess: (html jQuery ajax script: [ :s | s add: ((html jQuery: #postStatusTextArea) value: ''). s add: ((html jQuery: #activityStream) prepend: (CBActivityComponent post: self session user posts first)) ]) ]; Now it submits exactly once every time. However, other javascript functionality on the pages stops working. So my questions are, should the onClick be inside a block as in the second example, and if not, does anyone have any idea why the non-block version would serialize twice per click (some of the time). thanks much. Larry

UTF8TextConverter, GRPharoUtf8Codec, GRPharoUtf8CodecStream against GRNullCodec
by Marten Feldtmann 14 Oct '11

14 Oct '11

Hello, I have a question about what all these classes do (in a big picture) and how they work together and when they are actually called. I looked into the source code, but I am still having problems of fully understanding. When I have an Adapter with GRNullCodec I assume, that all (?) traffic, content (?) goes through the GRNullCodec, but due to the fact, that GRNullCodec does nothing, the traffic/content is not changed. What exactly goes through these codec ? If I use an adapter with GRPharoUtf8Codec is then the content converted to/from UTF8 ???? What does this mean to strings (in my application) I render on my pages like in the following command: html text: stringInSomeCodePage in both cases GRNullCodec and GRPharoUtf8Codec and with texts in specific code pages like Utf8, Latin1 and "true" Unicode (Utf32). In my firsts demos I held all my strings in UTF8 and used the GRNullCodec (and everything is ok in the browser side). Then I changed to GRPharoUtf8Codec and it seems to me, that I got now an additional UTF8 conversion. Then I switched my application strings back to Latin1 and it was ok again. How does this all work with Unicode characters with code points > 255 (and usage of GRPharoUtf8Codec) (in Squeak: WideString)? When is a GRPharoUtf8Codec really needed ?? Perhaps this is a stupid question .... but then I would like to know it :-)) Thanks for answering ! Marten

Q on "html select" and how to get selected item in an Ajax callback
by squeakman 13 Oct '11

13 Oct '11

Hello All, Is there a way to get the selectedItem when the Ajax callback is triggered in an html select? The following code snippet works for me but I think there must be a better way. (html select) id: 'stocksList'; list: self listOfStocks; onClick: (html scriptaculous request callback: [:i |self selectedStockIndex: i asNumber + 1.] value: self jsForGetSelectedIndex). Note that I am using the call:value: method. The "self jsForGetSelectedIndex" returns the javascript code that gets the selected index. In the callback: I use this returned value to figure out which item was selected. Is there a better way to do this? Thanks, Frank

Browser problem after installing seaside
by Javier 12 Oct '11

12 Oct '11

Hello, I'm new to the mailing list, and new to Seaside/Smalltalk. I'm having a problem after installing the new Seaside using ConfigurationOfSeaside30, and it is that, after installing it, my class browser no longer syntax color the code, and the completion stops. This happens both in Pharo or Squeak. I actually prefer installing Seaside this way, as I have written some classes and like the standard squeak/pharo image. I suppose this is due to the required packages of Seaside overwriting some of the classes in Squeak/Pharo. How can I solve this issue?

Redirecting to an error page etc., if an exception is caught using WAListenerAdapter
by John Toohey 11 Oct '11

11 Oct '11

Hi, I'm trapping all my apps exceptions in a custom exception handler, and would like to 1) redirect to an error page, or 2) emit custom HTML into the stream. However when an exception is raised and my handler is called, the WAStreamResponse is already committed, so I cannot do anything with it. Is there an easy solution to this problem? How are people dealing with this issue in general? -- ~JT

Q on Periodical
by squeakman 09 Oct '11

09 Oct '11

Hello, Is there any way to setup a periodical but not have it running initially? I guessed that using "evalScripts: false" would result in the script not being executed but that did not work. Here is the code that I am using: html script: ((html scriptaculous periodical) id: self domId; frequency: 5; on: self triggerMethod of: self parent; evalScripts: false; assignTo: 'FLPer'). What I want to do is have the script assigned to the javascript variable "FLPer" but not have it executed until a later time. Thanks for any help you can provide, Frank

[Seaside] Kaliningrad: Developing with Amber, Seaside and Monticello
by Dale Henrichs 09 Oct '11

09 Oct '11

If you've been interested in seeing how you might use Amber with Seaside, you should check out Kaliningrad[1]. The real purpose of Kaliningrad is to allow you save your Amber work in Monticello packages, but I used Seaside to implement Kaliningrad, so it is an example of how to integrate Amber and Seaside...
