Re: EOF related objects present a lot in the heap
hi @Chuck Hill The snapshots are referenced counted. (...) There is no way to accelerate this and I doubt it would be overall beneficial to do so. That would just increase the database traffic to re-generate the snapshot. The points which I see which could make it interesting for us are: - for some entities, we create a new record at change. Each record has all the data. As such, if 10 changes happen, only the latest record is actually used. The others snapshots there consume heap space for nothing and for quite some time, - we currently use a one editing context per session strategy. Our users potentially remain connected and active for hours. Whereas the data they deal with can have a short lifespan (1 hour or so). So some of the data may remain in the editing context while not being used anymore But it looks like we have others ways to look for right now. As far as I get it right now our best options to reduce RAM consumption looks like: - reducing the editing context scope (so they retain less), - switching to persistent sessions Any other hint/option welcomed :) @Musall Maik What would be the point of freeing some memory in WO only to allocate the same memory in another process? you're right in case of memcached. For our current issue putting it to the file system or db would be better. @Musall Maik Do you think it would be possible to not serialize out the session on each RR loop, but instead having a short timeout delay (like 10 or 30 seconds), make the session persistent once the timeout is reached, and keeping the actively used sessions in memory? Well, from my wicket experience and what was said here earlier, the cost of serialization is dramatically low. So adding 100 ms on each request and be sure to spare RAM would be ok for me. Anyway, once the mechanism is up and running, it's a matter of optimization. @Ramsey Gurley Do you have some estimate of the average size of serialized down sessions ? Approximations are fine: do we speak of Kb, Mb, Gb ? I guess a few Mb but then.. BTW, how does it play ball with the editing context snapshot ? Every time no RR is running all snapshots are cleared, is it right ? 2013/4/30 Chuck Hill ch...@global-village.net On 2013-04-29, at 2:11 AM, Musall Maik wrote: Am 26.04.2013 um 21:21 schrieb Chuck Hill ch...@global-village.net: On 2013-04-26, at 12:12 PM, Ramsey Gurley wrote: Disadvantages of persistent sessions: * Hard.

Re: All WOWODC 2012 recordings now available
why are we keeping videos private until they are a year old? they should be published right away so people can use them. And the hosting of WOCommunity.org and other things will magically be paid by magic? I had stopped working for ONE MONTH last year to work on my WOWODC presentations (and the organization, and editing the recordings) last year and I would have to pay for the WOCommunity hosting out of my pocket so that people who wants access to the content don't pay 50$ a year?

It's a tough decision. Running the community is not free, there are cost involved and the only revenue we have it the memberships. Early access to the videos is a significant incentive to purchasing them. The pessimist in me says that the ship has sailed on enlarging the community to any great degree. Certainly not to the point where risking the benefits that the WOCommunity org brings by sabotaging it's revenue stream makes any kind of sense. Some videos are always released immediately after WOWODC for free, and community members are always welcome to create their own and post them anytime they want.

Re: All WOWODC 2012 recordings now available
Jesse, I am certain that no one, you included, would give out your code for free in the interest of growing your business. If that were true, I am sure this community and others would follow in those footsteps. I have full confidence in the community leaders that they know what they are doing. They distribute what they can for free, but there has to be a limit in order to cover basic overhead.

A five page backtrack cache with a few hundred EOs in list pages serialized down to ~73Kb in my demonstration last year. Like the object store only tries to keep snapshots of changed EOs, the same happens for serialization. Unchanged EOs are just serialized using their global IDs. Only changed EOs have their values serialized by default. Naturally, your actual size may vary wildly depending on how you construct your components, how you reference your EOs, how many backtrack pages you allow, etc. Just using D2W, it is very light and fast. BTW, how does it play ball with the editing context snapshot ? Every time no RR is running all snapshots are cleared, is it right ? Yes. Just don't use the ERXObjectStoreCoordinatorPool.

Triggering AjaxObserveField through javascript
Hi there, I've got a series of WOPopUpButtons each with their own AjaxObserveField. They all have the same options and related to different objects. When manually manipulating pop-ups, everything works perfectly. I've also got another WOPopPupButton that is used to set the other pop-ups all at once. I set the values through javascript, and the selection fields on the page update, however their values are not submitted through AjaxObserveField. I have tried manually firing the onchange event in javascript, but it doesn't work. I had previously used the observeFieldFrequency attribute of AjaxObserveField to bypass this problem, but that causes issues with text fields (which are set up in the same manner). So, how can I get the javascript behind AjaxObserveField to update and submit these values? Thanks, -Taylor taylorchadden.com @drizztmainsword ___ Do not post admin requests to the list.

D2W Design Question
Hi, I'm trying to figure out something and I'm lost again. And I figure there is an easy answer so here goes: I'm using embedded components and I have a master list style page. On my inspect component I have an ERDActionBar that lets the user go between different screens such as inspect page, an edit page and different pages for special attribute handling and relationships. So here is my question: if I'm showing a list of objects from a to many relationship - how do I open a new page to edit one of the objects in the relationship without changing what the current object is and without using a modal window?

Re: D2W Design Question
Hi Johnny,
Ok, I admit to now being confused.
Your master list is D2W? Or is it just loading embedded D2W components below it?
When you said new page I interpreted that as new window. Not sure what this
looks like. Screen shots would help.
Is the link in question from a to-many relationship on your inspect page? Or is
it from the original list? I was assuming that you would be able to get the
object in the list, then pass that in your link to your new page. What object
is it that you don't want to lose reference to?
In case it helps, here is how I usually create a simple link for a situation
like yours. It could be in any page, really, but I usually put such a thing in
a list page:
.wo
wo:link action = $viewwo:str value = $displayValue//wo:link
.java
public class SelectDocumentForView extends ERXStatelessComponent {
public SelectDocumentForView(WOContext context) {
super(context);
}
public EOEnterpriseObject object() {
return (EOEnterpriseObject) valueForBinding(object);
}
public String key() {
return (String) valueForBinding(key);
}
public String displayValue() {
return (String) object().valueForKey(key());
}
public WOComponent view() {
Document selectedDocument = (Document) object();
return (WOComponent)
((Session)session()).navController().inspectDocument(selectedDocument);
}
}
rules:
100 : (pageConfiguration = 'ListMyWGDocuments' and propertyKey = 'title') =
componentName = D2WCustomComponent [com.webobjects.directtoweb.Assignment]
100 : (pageConfiguration = 'ListMyWGDocuments' and propertyKey = 'title') =
customComponentName = SelectDocumentForView
[com.webobjects.directtoweb.Assignment]
To set up a dummy propertyKey you just declare it in your displayPropertyKeys
for that pageConfiguration. So if 'title' wasn't actually a property, it would
still show up because I've declared a component for it. You'd change the html
above to display a static string instead of the value of the propertyKey.
Hope that helps,
David

Re: D2W Design Question
I have the power to confuse anyone when it comes to this WO/D2W!
OK. I created a screenshot with comments and I've posted it here:
http://www.kahalawai.com/ToManyLink.jpg
So yes... I'm using embedded d2w components. Each of the thumbnails is a link.
When the user clicks on the thumbnail it should keep the first two columns the
same and in the third column keep the action bar but replace the list of thumbs
with a form to edit the thumbnail (or create a new one).
The model is:
Product - Product Images - ERAttachment
The selected object in the display group is a Product the list of the thumbs
are Product Image eos.
I'm just trying to figure out how to put that component action in there... so I
keep the current selected object but I have a secondary selected object somehow.
Does that help? Or make any sense?
Thanks,
Johnny

code and a component that subclasses ERDInspectPageRepetition. I'm using
the subclass of ERDInspectPageRepetition to fetch the eos and print them to
the screen. So...
Is there an example of a custom link component in Wonder? Can I just create
a componentAction that sets the propertyKey to the dummy key?
I don't understand why I would use target = _blank? I don't want to
change the browser window? Or is that a special D2W thing?
Thanks a lot!

with the actual component, let me know.
