isolate
by recursive68＠gmail.com 26 Nov '19

26 Nov '19

Hi, Given it looks like the isolate method is never going to added back to the current or future versions of Seaside as it's been an open bug issue for the last 5 years, how in general would go about replicating it's behaviour ? I think it's a shame as I think this sort of functionality made Seaside standout from the crowd as a web framework. Thanks

JQAjax>>#script: in GemStone 3.3.1 with Seaside 3.2.1 works differently than in pharo
by PAUL DEBRUICKER 27 Mar '17

27 Mar '17

In Pharo I can use a #script: send like this html jQuery ajax callback: [ :json | self setMapBoundsFrom: json ] json: (JSStream on: 'map.getBounds()'); script: [ :s | s << ((s jQuery id: #'results') html: [ :r | self renderResultsOn: r ]) ] And the #results id has its content set to the value of the #renderResultsOn: method. In GemStone it seems like a page refresh is happening instead. Has anyone else seen this? I think it was happening in older versions too but I am not sure of what version combination.

Problem with JSScript vs JSObject
by Mariano Martinez Peck 02 Feb '17

02 Feb '17

Hi guys, Maybe it is because it's already Friday afternoon but I am failing to see something obvious probably. I render a div this way: html div id: self chartId; class: 'researchChartComponentChartContainer'; script: (chart wholeScriptOn: html). And the method #wholeScriptOn: does: wholeScriptOn: html | script chart | script := JSScript new. chart := self makeChartOn: html. script << chart. ^ script The method #makeChartOn: answers an instance of Highstock (subclass of JSObject). If I let the code as above, I get a client side error: VM4229:1 Uncaught SyntaxError: Unexpected token $ in JSON at position 0 However...if I change wholeScriptOn: to be: wholeScriptOn: html ^ self makeChartOn: html It works. So...what the hell is going on? As an instance of Highstock it works but as a JSScript it doesn't? They even seem to print the same #asJavascript. Any idea? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

If someone is smart-enough and wicked enough to bypass your client side checks, you don't need to be user-friendly to them. The server checks are more to protect your server from them. You are right. I am convinced. I will add client side checks. Thanks for your answer, Ben. Cheers, Bernhard

problem with lightbox:
by Johannes Brauer 22 Jan '17

22 Jan '17

Hi, I have a problem using lightbox: (scriptaculous-components-call/answer): When the lightbox appears the page (root component) beneath it is rendered without any css applied. After closing the lightbox the page is displayed well again. I could not figure out what I am doing wrongly. I am using Pharo 5 and Seaside 3.2. Johannes

How to define the duration of my sessions
by Sabine Manaa 22 Jan '17

22 Jan '17

Hi, how can I define the duration of my sessions? >>application cache expiryPolicy configuration at: #cacheTimeout put: 120. does not work any longer (no implementor of #expiryPolicy) In the comment of WASession there is the text "If the session has not been used for #defaultTimeoutSeconds, it is garbage collected by the system. " but there is no implementor of #defaultTimeoutSeconds. And 2nd question, is it possible to define a certain task to do from my session instance if the session is unregistered because of duration? (e.g. write sth in a log file) (From the class comment also: WARegistry clearAllHandlers. does not exist any more) Regards Sabine -- View this message in context: http://forum.world.st/How-to-define-the-duration-of-my-sessions-tp4930014.h… Sent from the Seaside General mailing list archive at Nabble.com.

Bad Request ZnEntityTooLarge
by Bernhard Pieber 20 Jan '17

20 Jan '17

I have a Seaside application which includes a file upload feature. renderContentOn: html … html fileUpload callback: [ :file | self receiveFile: file ]. html submitButton: 'Upload‘ ] … In receiveFile: I just save the uploaded file on the file system. When I upload a file larger than 16 MB an error page is shown with the error message: Bad Request ZnEntityTooLarge I found that by using ZnConstants>>maximumEntitySize: I can increase this limit. However, I want to catch this in the image and show an error message to the user. I tried wrapping receiveFile: and renderContentOn: with an on:do: exception handler for ZnEntityTooLarge. However, neither works. It seems that the error happens before renderContentOn: is even called. I searched the mailing lists but did not come up with an answer. How can I achieve this in Seaside? Any help would be much appreciated. Cheers, Bernhard

How can I provide AJAX calls to 3er party libraries?
by Mariano Martinez Peck 13 Jan '17

13 Jan '17

Hi guys, I know how to use AJAX but always everything inside Seaside. I know need a way to provide JSON responses to AJAX calls made by a 3er party lib. For example, in Highstocks [1], there is an example like this: /** * Load new data depending on the selected min and max */ function afterSetExtremes(e) { var chart = Highcharts.charts[0]; chart.showLoading('Loading data from server...'); * $.getJSON('https://www.highcharts.com/samples/data/from-sql.php?start= <https://www.highcharts.com/samples/data/from-sql.php?start=>' + Math.round(e.min) +* * '&end=' + Math.round(e.max) + '&callback=?', function (data) {* chart.series[0].setData(data); chart.hideLoading(); * });* } So... how could I provide that at my server side? Above JS would be code that I write in Seaside and it is passed to the client. Therefore, I THINK I am able to write that JS generating a URL with the correct _s and _k or whatever.. Thanks in advance for any lead you can give me here. -- Mariano http://marianopeck.wordpress.com
