Re: didUpdate?

Hi Theodore, I agree with George, I wouldn't do the Session way. Worman set you on the right track. Ok, it didn't fully give you the solution but it pointed you where to look. The EOEditingContext knows all. It knows what the current values are (just invoke methods on the EO itself) it also kn

Re: Fluffy Bunny question

Hi Sharpy, Jesse, and John, I appreciate your replies. We are running Applications that only extend the ERAjax lineage bypassing full blown ERXApplication. We are using almost the same as you Sharpy. Same Eclipse version but newer WOLips. Specifically we're running: Eclipse 3.7.2 WOLips 3.7.201

Fw: Fluffy Bunny question

Hi WOrriors, Sorry for the cross post but it seems these days most questions get asked on the Apple lists regardless if they are pure Apple related or WOLips / Eclipse / WOnder related. Anyone have some advice for me? I'd like to put my EOModel files into "Resources/model" but fluffy bunny isn

Incremental build - development via Web adaptor

Hi WOrriors, Big question: How can I we get an incremental build to embed framework static resources into the app's "build" folder? We're in the midst of converting an app from XCode to Eclipse and have some questions about using either the "incremental" build setting that puts products in the

Re: Migrating from EOF to ????

Hi WOrriors, The Tapestry API changes are way more than that the API changes we faced in WO 5.4.3 from 5.3.3. However, we had to deal with WO API changes for no real benefit. No boost in productivity. Nothing broken in 5.3.3 that WOnder had not already addressed. Still, we happily alienated A

Re: Migrating from EOF to Cayenne

Hi WOrriors, I still question why we are fighting so hard for Object-relational mapping. If we are contemplating doing work, shouldn't we consider going straight for object databases? Take out the transcription layer. Let's get more productive. Only use OR-mapping for old systems that we must

Re: Migrating from EOF to Cayenne

Hi WOrriors, I have mixed feelings. It's obvious when you look at Cayenne the original developers had used EOF before and wanted to make an open source clone. They also wanted to make it better, if possible, than EOF. It's been a while but when I looked at it I was put off by some things. Th

Re: I am going to write a WO book

Hi Markus, Good for you! Thank you for even thinking about this. You ask what you should say about WOnder? I'd recommend the following: 1) Defining what the project is and some history 2) Show how to integrate it in your app, the pre-requisites. 3) Leave it at that. You kind of have to do thi

Re: Restoring session after timeout.

Hi Mahdi, The session is not just a cookie. It is a reference to many objects stored in RAM for one user. It's what allows a web application to "remember" what a user is doing. It can eat up a lot of resources but is very convenient. That thing you are currently storing in a cookie is just a "k

Re: Why are static web resources duplicated in the app bundle?

Thanks Q for the tip. Looks like you are right on the money. I asked my buddy "JD" what the heck you are talking about since WODeployedBundle.relativePathForResource() is undocumented. It in turn calls _preloadAllResourcesIfNecessary() which is where the fun really starts to happen. Here's w

Re: Why are static web resources duplicated in the app bundle?

Good thought Chuck, I checked and the app I was testing and it has direct connect disabled. I guess somehow deep in the bowels of WO it just expects the duplication to be there. And, as you say, perhaps it is tolerated because you might at some point want to turn on Direct Connect mode to test

Why are static web resources duplicated in the app bundle?

Hi WOrriors, Do any of us know why static web resources such as images and javascript files get duplicated during a split install? Surely they need to be in the .woa that resides under the Apache root but why are they duplicated in the other .woa alongside the java logic? I've seen this for ma

Re: Finding WO people for startups (cult of the dead)

Hi Chuck, Simon, and all WOrriors, I certainly understand your concerns and they are valid. WO is already a very expressive framework and you have a work process that simply does what you need. You are agile and get things accomplished. You don't have a need to try something new. I also underst

Oracle and Sorting Null Values - everyone thinks different - everyone is correct

Hi Dave, You asked if null should be universally "less than" non-null. No, everyone thinks differently. For us it is the opposite. We use Oracle and like the way it sorts. We want "null" to be greater than "non-null". That is because for our domain we want to see values that have something "in

Hello WOrriors, We're using WO 5.3.x (not 5.4.x) I've run into a pickle where if I do an ec.deleteObject() and then call ec.saveChanges() I find that this fails during a "validateFor*Save*". Curious, indeed, because it should only call "validateFor*Delete*". When asking the EC to delete the Ob
