Using a link (http GET) in VisualWave

HI There,

I'm new to VisualWave and I am trying to do something that is pretty common in the Perl/CGI world but I can't figure out how to do it in Smalltalk.

Basically, I want to display a list of records on a screen represented by an HTML href's. When the user clicks on the link, I want to display more details about this record. I can get it working with a button, but I'm not sure how to do this with a link. When I tried to pass a parameter such as 'id=1' I got a walkback saying the message id=1 was not understood. Is there a way to do this in VisualWave?

Thanks,

Steve.

I'm not quite sure how you're trying to do this that's causing problems. In a pure VisualWave application (by which I mean, just a VisualWorks GUI, that's automatically being translated into web pages, with initial URLs of the form .../launch/ClassName) then it should just work. You write it as if the user were clicking on the list, and the web page updates. I like to use a nicely recursive example of that, by using ../launch/ServerConsole. At which point you get the server console for administering the web server as a web page. Not everything works on it, but it certainly has a list.

Or are you doing something else? I'm not sure how you mean that you're trying to pass the parameter.
