Re: [rules-users] help! the field *** is not visible

A better approach would be to use:- rule system will execute 'tc' command when Server(message8388608) then System.out.println(The network is so crowd that it needs repairing.); Runtime.getRuntime().exec(tc);#execute the tc command end This assumes you insert Server facts into

[rules-users] completing persisted workItem doesn't complete a process

hi, i've a very simple process with only 4 work items that run async. For steps WI1 WI2 i complete each step but when the process reaches WI3 step i manually kill the whole process and then load it from a database i.e. ksession.loadStatefullSess.. Now after i complete WI3 step i can see that

[rules-users] Insert an object containing a HashMap

Hello, I have searched the forum for information on this case, but I haven't find, at least yet. I am trying to insert an object containing a HashMap, but when I call ksession.insert( fact ) method I get this error: java.lang.ClassCastException: java.util.HashMap cannot be cast to

Re: [rules-users] completing persisted workItem (the last in a process) doesn't complete a process

hi, two updates to the previous post: 1. it looks like the reason why i can't see the process status changed to COMPLETED is because of something going wrong with JPA and what a session obtained using its API can see i.e. my custom work item code looks like below: public void

Java or DRL declaration of the fact object, please? Also, are you using the HashMap field of that fact in any rules, and if so, how? And, perhaps, the full stack trace? -W On 12 April 2011 14:06, hbunny off...@interdevelopments.ro wrote: Hello, I have searched the forum for information on

Re: [rules-users] help! the field *** is not visible

Try adding 'dialect mvel' (no single quotes) after the rule name to the top of each of the rules. I have seen this error before and doing this resolved the issue. hello,everyone!I wrote a rule with Drools,but the error told me that the field Server.Message is not visible, I can't find how it

Re: [rules-users] help! the field *** is not visible

Still, accessing the class field com.sample.Server.Message in eval() in this way is almost certainly not a good approach. But note that dialect mvel may be written preceding all the rules it should apply to. -W On 12 April 2011 14:38, John Peterson john.peterson.g...@statefarm.comwrote:

[rules-users] Existing Test Harnesses for Drools?

Re: [rules-users] completing persisted workItem (the last in a process) doesn't complete a process

for those interested the problem was that i misinterpreted ProcessInstance object as something that always gets updated whenever underlying process changes, whereas in fact that's the version of a process obtained at the specific moment. This is especially true while working with persistence. So

Re: [rules-users] completing persisted workItem (the last in a process) doesn't complete a process

I ran into this issue also. I was told that the ProcessInstance you are looking at is just a snapshot of what was loaded from the DB. It doesn't get updated after being loaded. I wasn't told why this was the behavior, just that it was expected. Didn't seem intuitive to me. I was told that the

[rules-users] is it correct that rows in a sessioninfo table in df persistence never get deleted?

hi, i'm not sure whether it's OK or not but while using drools flow persistence records in [i]sessioninfo[/i] table never get deleted ? Once i'm done with the process and call knowledgeSession.dispose() previously created record in a table doesn't get removed? Is it correct that sessioninfo table

Re: [rules-users] completing persisted workItem (the last in a process) doesn't complete a process

A process instance is disconnected once the command is completed. This means that it will represent the state at the end of the command and won't be updated when the process instance actually changes. You can however always get the latest snapshot using ksession.getProcessInstance(id).

Re: [rules-users] is it correct that rows in a sessioninfo table in df persistence never get deleted?

Yes, as disposing a session doesn't mean you don't want to restore it at some point later from persistence. You might for example temporarily want to dispose the session since you know it is no longer needed (short-term) and recreate it later whenever necessary. If you don't need the session
