Re: [rules-dev] RE: [rules-users] Compatibility of Rule Flows from 4.0.7 to 5.0.0

Hi, I have raised a feature request for this https://jira.jboss.org/jira/browse/JBRULES-1797 and also submitted a patch (JBRULES-1797.patch.zip) for the same. If there are any changes in the patch kindly let me know.

Thanks.

Easiest check would be to see whether the XML contains element called as "process". Since XML Parsing is internal to the individual releases (4.0 uses XStream and 5.0 uses XMLReader), I am not sure whether we should form a XML document from the reader to check if the process belongs to version 4.0 or compliant. Brute force check would be indexOf ("<process") >= 0 then it is 5.0 else 4.0 ;-). I am sure there would be better ways than this kind of check. I do not mind taking this further. Due to lack of in depth knowledge about drools, I am not able to decide what the approach should be for checking the version. This would be a really good feature as it would mean that drools 5.0 is backward compliant for rule flows J. And this adds lot of confidence to enterprises. p.s. Since this was now moving towards dev, I have moved the thread to the dev mailing list. Thanks.

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.

I suggest that somone in the community starts looking into an XSLT to translate them.

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 MASTEK LTD. Mastek is in NASSCOM's 'India Top 20' Software Service Exporters List.
