[rules-users] Compatibility of Rule Flows from 4.0.7 to 5.0.0

[Nimesh Muley]

Hi,

I have attached a file for translating rule flows from 4.0 to 5.0. I have tested my flows with the XSL and it works fine. However, the XSLT may not be quite slick or compact as I have touched upon XSLT after a long time. I have covered all the nodes available (ruleSet, start, end, join, split, milestone, action and subProcess).

There is one issue in the XSLT. I have not added the xmlns attribute to the process element. Reason is that this attribute appears in child nodes too with empty string, even though it is not mentioned for the child nodes. This attribute is needed in the 'process' node because the Eclipse editor for 5.0 ignores the process node if there are more than 2 sub processes in that ruleflow. Am not sure why this is happening but that has been my observation.

In case XSLT is not present as an attachment then let me know the location where it can be uploaded.

Thanks.
Regards,
- Nimesh

No they are not compatible, 5.0 has a new ePDL XML language that is human writable. I suggest that somone in the community starts looking into an XSLT to translate them.

Hi All,

I wanted to know if RuleFlows made using the Eclipse 4.0.7 RuleFlow Builder will work with 5.0.0.  When, I try to upload a 4.0.7 ruleflow into Guvnor, I get a NullPointerException and before that the following:

Cannot find the declaration of element 'org.drools.ruleflow.core.impl.RuleFlowProcessImpl'.

I checked the 5.0.0M1 jars for drools-core, and this class seems to have been removed from there. Also, after installing the 5.0.0 plug-in into Eclipse, my rule-flow nodes have all gone.


Also, this may be a minor bug but it says(both in the docs and the BRMS Guvnor M1 Release):
"Ruleflows allow flow control between rules. The eclipse plugin provides a graphical editor. Upload ruleflow .rf files for inclusion in this package.":

Should the .rf say .rfm ?

Cheers,
Vikrant
