[jboss-user] [JBoss jBPM] - NullPointerException in Decision.java
Just to continue the 3.2 Decision discussions... With the Decision patch (as described in http://jira.jboss.com/jira/browse/JBPM-854) applied, I'm getting a NPE at line 112 in Decision.java. This is whilst executing against a jbpm 3.1 database that's been upgraded to jbpm 3.2. It seems line 112 can just be removed and that fixes it. I've raised the following JIRA issue http://jira.jboss.com/jira/browse/JBPM-968.

[jboss-user] [JBoss jBPM] - Upgrade database schema from 3.1.2 to 3.2
I've gone through the process of upgrading existing 3.1.2 jbpm instances to 3.2. I had to set some default values for new 3.2 columns, most of which had reasonable defaults. However, a version_ column has appeared in several places - what is a reasonable default value for the value_ column? I've used 0 for now.

Any update? We embed jBPM, so our community of workflow developers do not know of the starter kit. Instead, we just point them to the jBPM on-line docs, but the contents of the URL have just changed. We could host the docs ourselves, but rather not do so.

[jboss-user] [JBoss jBPM] - Parallel Review Process: template process definition
I believe the jBPM community can greatly benefit from a library of demo/template process definitions for common workflows. The current code samples, docs & references to workflow patterns concentrate on the low level building blocks, but it requires a blind jump and effort to pull together the blocks into a coherent workflow. So, to start, I'd like to put forward the following template definition for supporting a review & approve process where 'N' parallel reviewers can approve or reject. Approval is only reached when a specified percentage of the reviewers approve. A custom 'ForEachFork' (modified from the contribution on the wiki) is used to implement the parallel part. The process variables 'reviewers' (a list) and 'required_approve_percent' need to be provided when starting the workflow. Is there a better way? Would it be useful to start a library of these on the WIKI?

[jboss-user] [JBoss jBPM] - Token lifecycle with fork and join
Jbpm 3.1.2 I have a simple process which includes a fork and join. It functions as one would expect, however, I do have a query regarding the lifetime of tokens during the process execution. Upon reaching the fork, child tokens are created; one for each path. When all child paths reach the join, the process continues. However, if I use ProcessInstance.findAllTokens() at this point, it returns the child tokens for the previous fork & join. Each token is still active (according to Token.hasEnded()). Is this correct? I would at least expect those child tokens to have been ended. Actually, I wouldn't expect to get those tokens from findAllTokens(), as that's all happened in the past. Any light on this subject appreciated?

[jboss-user] [JBoss jBPM] - log.debug
JBPM 3.1.2
In VariableContainer.java there are unprotected log.debug statements such as:
log.debug("create variable '"+name+"' in '"+this+"' with value '"+value+"'");
This is fine for simple values such as strings etc, but we have some object
types whose toString() is a little more heavy. Even when debugging is switched
off, the toString for value is being called.
Can these calls be wrapped in log.isDebugEnable() in future versions of JBPM?
Should I raise a JIRA issue?
Thanks,
David Caruana

[jboss-user] [JBoss jBPM] - Re: unable to delete process instance
JBPM 3.1.2 With 3.1.2, I get similar constraint violations from FK_VARINST_TKVARMP, in the table "JBPM_VARIABLEINSTANCE". I too manually delete variable instances before deleting the process instance, but I still have cases where this does not work resulting in the above constraint violation. I'm attempting to find a simple reproducible test case, but don't have one yet. Anyone have any reliable code for deleting a process instance? Thanks. Should I raise a bug in JIRA?

[jboss-user] [JBoss jBPM] - Alfresco has embedded jBPM
Hi jBPM developers and contributors, For the last couple of months we've been embedding jBPM into Alfresco. We've found the quality of the jBPM code, documentation and examples to be very good and haven't really needed to use this forum too much! Excellent work. The integration has involved: 1) Layering the Alfresco Web Client User Interface onto jBPM - this means using our own meta-data support to describe the data required by a process and each task and having that drive the Alfresco UI dialogs. 2) Encapsulating jBPM behind a service-oriented API - potentially allowing RMI or Web Service access. 3) Allowing jBPM process context and task variables to reference objects inside the Alfresco Content Repository - jBPM beanshell scripts can navigate the repository and perform operations (such as checkout,checkin, transform). 4) Using Spring Modules to tie Alfresco & jBPM persistence and transactions 5) Hooking into various jBPM plug-in points such as Value Converters, Task Factory etc I understand that work around task meta-data and task dialog rendering is taking place for 3.2. We'd be happy to share our experience in this area. A preview of this integration will be available soon - some documentation can be found on our wiki at http://wiki.alfresco.com/wiki/Workflow. Thanks.

[jboss-user] [JBoss jBPM] - Error handling in GPD process deployment
GPD 3.0.11, JBPM 3.1.2 I've noticed the error handling to be erratic when deployment of a process archive from the GPD fails. Often, a dialog is presented stating the deployment succeeded when in fact it hasn't. Other times, a dialog is presented due to an unexpected error. Two extremes. The deploy servlet returns arbitrary messages in the response for certain exceptions e.g. FileUploadException, IOException, but for others, just leaves the exception to propagate, presumably forcing an HTTP error response. However, for valid HTTP responses, it seems the content is completely ignored by the GPD. Obviously, an improvement would be to present the cause of the error in the GPD and to also catch all errors. However, I raise this as I'm developing my own deploy servlet to fit the setup of our server, but it's not clear what the protocol is for reporting an error. For now, I've kept as close as I can to the error handling in UploadServlet.

[jboss-user] [JBoss jBPM] - Re: 3.2 Timeline?
Thanks for the prompt responses. Given our timelines (heading for a 1.4 qa cycle in sept), I think it's best to stick with 3.1.2 for now. However, your plans for 3.2 sound ideal, allowing us to try early 3.2 drops on our 1.5 dev line. Initially, we're going to build JSF components (inbox, start process, task view ) that integrate with the rest of Alfresco's JSF based UI and look & feel. Over time, we'll introduce more workflow interaction within Alfresco. I'm not the JSF expert, but members of our team have now gained deep experience from developing the Alfresco UI (and DCTM's Webtop) of this type of technology. I'm sure we can help each other. Our WCM team will be introducing Chiba into our stack, so who knows, we may in the future use xforms for managing tasks etc. We're just taking it step-by-step for now :-) Regards, David View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960622#3960622 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3960622 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [JBoss jBPM] - GPD deployment and commons file upload version
Hi, After some "tweaking" of the jBPM Console Webapp, I've managed to loosely integrate the bpm stack with Alfresco's tomcat stack (thanks to some help from Spring Modules), such that db connections, transactions etc are shared between jBPM and Alfresco. By "tweaking", I mean I've had to modify some oddities around using request scoped beans, request parameters, assigning unique ids to controls and using Alfresco's logged-in username for task list retrieval etc - I'm not the JSF expert, but for now it helps us test jBPM in the context of Alfresco's stack. Btw, we do intend to build Alfresco specific UI for task handling within Alfresco, but otherwise we intend to fully embed the jBPM engine as is (plus extensions). So, my first question, of which I'm sure there will be plenty more! Our stack is using commons-file-upload v1.1.1, and it seems this is incompatible with the GPD v3.1.2 deployment process. The gpd is passing a request containing a Content-type whose multipart seperator is "," whereas the file-upload utility is looking for ";" - file-upload v1.0 seems to check for "," (or at least it works). I think http specifices ";". Any ideas how to work-around this? I don't really want to have a special build of the GPD v3.1.2 (at least for now). Will v3.2 (HEAD) change this request? Unfortunately, we have to use file-upload v1.1.1 for portal compatibility.
