How to start an image with PORT parameter

I wish there was an easy way to show this, but I'll try to describe it well...
I'm using this statement... (html jQuery: '#display') html: [:r | r render: (self renderResultsOn: html)]. ... in order to render the results of a survey. On the page I have a simple select menu and a button that let's you pick between the available surveys. What is happening is the page is being loaded fine, I can select the survey fine, hit the button, the results display fine, but then the original div with the dropdown and button is also added to the bottom of the #display div (see above). The display div is simply: html div id: 'display'. I've tried taking the div out of the #with: statement where the select box and button are also in, but that does not seem to help. There are a couple other places I have been using the jQuery replace code, and it appears to be working correctly in those instances. Thanks, RS Windows Live™ SkyDrive™: Store, access, and share your photos. See how. _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Are you sure the DIV is still there when you perform the action? jQuery simply ignores actions on queries that do not match anything, that's sometimes quite confusing. If that's not the problem, then FireBug should tell you more in form of an error message.

<div id="surveySelect" class="questionDisplay">
<select> Selects the survey </select> <br/> <button> View this survey. </button> <div id="display"> <div> a result </div> <div> a result </div> ... <div id="surveySelect" class="questionDisplay"> also contains select and button </div> </div> </div> I don't think I'm getting any errors from FireBug (I'm not sure what they look like either). The div is there, though, or the results wouldn't been rendered at all. Nothing would happen when you click the button. Somehow, it's getting a copy of the containing div in there with it as well.

While I'm no expert, I found this Firebug tutorial helpful:

That is a nice little concise tutorial. I guess I didn't have the console enabled :p
I do get this error: parent.dap_Resize is not a function <img src="chrome://firebug/content/blank.gif" title="Break on this error" class="errorBreak"> if(typeof(inDapIF) != "undefined"){paren...ap_Resize(document.body.id, 120, 60);} That seems to be unrelated, though.

I may be misunderstanding your problem but shouldn't that be:
(html jQuery: '#display') html: [:r | self renderResultsOn: r] ? It looks pretty weird to me that you are trying to render the return value of a rendering method...

Erm... not sure what you mean.
The rendering block needs to be invokable later, long after the page has been rendered and the original canvas (in the method parameter 'html') has been cleaned up. In order to make this work, the rendering block gets passed a new canvas each time it is invoked (via the block parameter 'r'). So you need to make sure that you only use the new renderer and not the old renderer from within that block (not that the Slime package provides Lint tests that will catch this for you). Also, remember that the #render: method expects a "renderable" object. This could be a Component, a Block, or any number of other things. I assume your #renderResultsOn: method was returning self and that was causing the whole Component to be rendered again each time the block was called.

Hmm... I'll have to think about that when I get back to this after work. I'm pretty much throwing myself into this and going with what works. I really need to sit down and read and understand what it is that's going on behind all these different methods and whatnot, but I am finding it hard to read through some of this code for some reason. The comments and stuff help sometimes... I guess I am just more of a hands-on learner :)
Thanks for the help!

It's not your fault at all. This stuff can get confusing (and if
nothing else it's different). The comments don't always do a good job of making it clearer. I wonder if I could do a blog post on the scope of renderers... I'll think about it. Asking here is exactly the right thing to do and it helps us see where the confusion is so we can prioritize our efforts to make things better. If you see specific places methods or classes where better comments would have helped you, please let us know. Julian On Mon, Jul 20, 2009 at 9:24 AM, Robert Sirois<[hidden email]> wrote: > Hmm...

Are you meaning to kill a given process started with nohup in unix/linux? You must search its PID and kill that pid with kill PID or, as Philippe said. > I mean, I have a similar script to yours called "startApp.sh" but I > want to do another called "stopApp.sh". If you are using the script passed to the image on start up that I posted the other time, you can, in a forked process inside the image to constantly search for a file in a given path. When found, you call snapshot on the image and quit. This way, you start the image without the file on the path and when you need to shut them down, you create an empty file on the path, the images notice it and shuts down. You can even give each image a different file name to search for and stop the images independently. > The only way I saw to do this is to do a killall squeak but I don't > know...what happens if I have more than one vm/image ? > killall kills all the process named some form. If you have several processes for example of firefox, a killall firefox will kill all of them.

Careful with broad statements like that. On at least one flavor of unix, "killall" killed *all* processes, not just ones matching a parameter. I forget where to find the anecdote, but it was very disturbing. [looking with google] Ahh, here it is: http://en.wikipedia.org/wiki/Killall The implementation supplied with genuine UNIX System V (including Solaris) and with the Linux sysvinit tools (as killall5) is a particularly dangerous command that kills all processes that the user is able to kill, effectively shutting down the system if run by root. Heh. That *would* be surprising. -- Randal L.

How can I know the PID from a process I > started from nohup? Suppose I have this script: > In a script or a unix shell, you, after executing a command, can use $! to obtain the PID of the last process and $? to obtain the exit code of the process. Then you can use this variables to form the name of a file or to store it on a file to subsecuent use, like killing the process later. e.g miguel@laptop:~$ evince & [1] 13500 miguel@laptop:~$ echo $! 13500 miguel@laptop:~$ echo $? 0 miguel@laptop:~$ echo $! > evince.pid miguel@laptop:~$ cat evince.pid 13500 miguel@laptop:~$ man kill miguel@laptop:~$ kill -9 `cat evince.pid ` miguel@laptop:~$ that are backticks around the cat command.

Generally, send 15 (SIGTERM), and wait a second or two, and if that doesn't work, send 2 (SIGINT), and if that doesn't work, send 1 (SIGHUP).

Sometimes, you just want to get rid of a process no matter what, but I agree with you. So Mariano, listen to Randal.
