How do I widen this column?
by David Pennington 30 May '21

30 May '21

I have some columns in a page that display amounts. As you can see, one of the columns is wide enough for the minus sign but the other column is too narrow and the minus is forced onto the line above. Both entries come from the same printString code so there should be no difference in their presentation. Can anyone explain how to sort this out? David

Accessing renderContext actionUrl
by Jupiter Jones 26 May '21

26 May '21

In a component I’m wanting to construct some custom urls. In a JSObject subclass I can start with: myActionUrl := self renderContext actionUrl copy How would I do that from within the WAComponent hierarchy? I can’t see how to access the render context. Cheers, J

jQuery dialog question
by Louis LaBrunda 25 May '21

25 May '21

Hi Everyone, I'm trying to use the jQuery dialog as a replacement for the JavaScript alert() function. I'm using VA Smalltalk v9.2.2. The code below opens the dialog when the image button is clicked but closes soon thereafter. Does anyone have any idea why and what I can do about it? Or have a better way of doing it? Lou help: aString on: html "Create the html to display the help string." | helpString id | helpString := aString copyReplaceAll: LineDelimiter with: '\n\'. html div id: (id := html nextId); script: (html jQuery new dialog autoOpen: false; html: [:r | r label class: 'Label'; with: helpString]; title: 'Help'; width: 1000; resizable: true; modal: true). html space. html imageButton class: 'HelpImage'; title: ('Popup Help - ', aString); url: theSession helpUrl; onClick: (html jQuery id: id) dialog open. -- Louis LaBrunda Keystone Software Corp.

Re: [Seaside] Executing form callbacks within a block
by Esteban Maringolo 24 May '21

24 May '21

Well.. I'm not writing the values directly to the database, but I'm using GLORP in between. Glorp detects changes and at the end of a "unit of work" (kinda transaction) it creates the corresponding statements to write/update/delete rows in the database. But in order to do that it has to know the object "state" before starting doing mutations on it. So what I finally did was to have a hidden input as the first callback. A super simplified version, without validations and whatnot is like this: html form: [ html hiddenInput callback: [self db beginUnitOrWork. self db register: self model]. html textInput on: #name of: self model. html submitButton callback: [self db commitUnitOfWork] ] Regards!

Executing form callbacks within a block
by Esteban Maringolo 20 May '21

20 May '21

Hi all, I have a situation where I want to execute _ALL_ the callbacks of the inputs in the form within a particular block (basically, a DB transaction). html form: [ html textInput on: #name of: self. html textInput on: #age of: self. html submitButton ] I want to execute the three callbacks within something else, or at least have the option to execute something before the first callback executes and ensure something gets executed after the last one is executed. I know it involves fiddling somehow with WACallbackProcessingActionContinuation, but it's not fully clear if I could do this. The hacky alternative would be to have a hidden field that does start the tx and the submit / cancel commits or cancels it. html form: [ html hiddenInput callback: [self beginTransaction]. html textInput on: #name of: self. html textInput on: #age of: self. html submitButton callback: [self commitTransaction]; value: 'Submit'. ] But in this case I'd have to keep the tx "outside" of the form, and I'd like to wrap everything in a single block. Is there a way to do this with Seaside? Thanks! Esteban A. Maringolo
