RE: [rules-users] Basic questions about rule deployment
Just a note about URLs. URLs will automatically do base 64 encoding, which primarily means that all spaces are replaced with %20%. If you are using a URL to represent a file, make sure you test it with a file that has spaces somewhere in the path. I just learned this the hard way. You may need to convert your URL to a URI.

Re: [rules-users] Basic questions about rule deployment
Replacing a space with %20 has nothing to do with base 64 encoding. It's called percent-encoding (in RFC 3986) and it's required for valid URI. You may be confusing terminology here, but your point of testing with space-containing filenames is well taken. - Godmar On 10/11/07, Hehl, Thomas [EMAIL PROTECTED] wrote: Just a note about URLs.

Re: [rules-users] Basic questions about rule deployment
Thanks for the warning! I tested this with a path that contains spaces. For some reason I don't have any problems with the corresponding URLs. Nevertheless I tried to convert those URLs into URIs and THEN I see the problem of the spaces not being accepted. As the URLClassLoader takes URLs, this is not really an issue for me so far. Still I don't really understand what is going wrong, as I had the impression that URLs are a SUBSET of URIs. But this relationship seems not to be strict... The only thing I can say is that my app works with spaces inside the path without the need of the described URI-workaround. -- View this message in context: http://www.nabble.com/Basic-questions-about-rule-deployment-tf4601653.html#a13155173 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] activation-group not canceling other rule members
All, ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] activationCancelled() not being executed?
It is really difficult to answer that since your understanding seems correct. Is it possible for you to provide a self contained test showing the problem? []s Edson 2007/10/11, Fermion [EMAIL PROTECTED]: It's been a while since I had time to investigate this problem. I followed your advice and hooked up the DebugAgendaEventListener to my workingMemory instance. This clearly shows, that my activations are created but never canceled. So at least it is consistent with what I'm observing in my application. But before I start even considering it being a bug (I'm quite sure it is not), maybe it's better to understand what is happening in my code: I think that I nailed my problem down to an issue with my fact IDs: If I have, for example, a real world value (lets say a temperature) that is connected to a java bean, my understanding is, that the fact ID of this value inside the workingMemory should not change, even if I change the real world value (temperature rises)(and thus the java beans value). In fact the change is propagated to the working memory (as I call firePropertyChange inside my bean), but a NEW rule is activated by the changed fact, having a DIFFERENT fact ID! I'm quite sure that this is the reason for my problem with the missing cancellations. I'd assume that for a rule to be canceled the fact with the CORRECT fact ID would have to be changed. Now, in my application, it seems that every modification creates a NEW fact inside the working memory (which is of course not, what I want). I had the hope, that calling the firePropertyChange from inside the beans setters would notify the working memory automatically about the correct fact-ID. I checked my equals() and hashCode() methods but the hash code is always constant and equals is correspondingly true. I also checked that I don't accidentally re-assert the fact on modification. So what I don't understand is WHY the working memory thinks that the fact ID has changed...

Re: [rules-users] activationCancelled() not being executed?
Hi, as you might have noticed, I'm trying to avoid supplying a self-contained test package. The problem with that is, that my application code has grown quite a bit and it will not be very easy to extract the code. Nevertheless I will provide such a test package, should I not succeed in finding the error myself very soon. As I have next to no experience in Java, I just want to rule out that it is no stupid Java-beginner mistake. Actually I'm quite sure that it is; otherwise the bug would most likely be known to someone in the community. Therefore I will first clean up my code a bit more. Thanks for the help anyway and I'll report back... fermion -- View this message in context: http://www.nabble.com/activationCancelled%28%29-not-being-executed--tf4348054.html#a13162482 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
