Oryx: Not able parse the knowledge when adding Message Events or Send Task Node

[uvijayreddy657]

I am getting the following exception when loading the process which has Intermediate Message Event(i.e. Email Notification Nodes)  or Send Task nodes

URL url = new URL(guvnorRepoURL+ "/drools-guvnor/rest/packages/pkg/assets/" + assetName+ "/source/");

kbuilder.add(ResourceFactory.newUrlResource(url),ResourceType.BPMN2);

KnowledgeBase kbase = kbuilder.newKnowledgeBase();  //Getting error at this statement

[tsurdilovic]

Could you please test with the latest from master: http://people.redhat.com/tsurdilo/oryx/latest/ and let us know if you still run into issues. Please note that this is NOT AN OFFICIAL RELEASE.

Hope this helps.

[uvijayreddy657]

Tihomir,

I tried with the both latest wars designer-1.0.0.055-jboss.war and guvnor-distribution-5.3.0.CR1.war.

Now I am not getting exception for Message Intermediate Event. But when adding "Send Task" node getting the following exception.

For Send Task Node:

Thanks for your quick replies.

[tsurdilovic]

Could you pastebin or gist your bpmn2 so I could test locally? If you have a test case (java) that would be nice to have as well.

Thanks.

[uvijayreddy657]

Tihomir,

I am in a small confusion about email notifications which node to use in the oryx. Whether I should use Catching Message Intermediate Event or Throwing Message Intermediate Event or Send Task or Recieve Task.

thanks.

[tsurdilovic]

Hi, if I understand your question correctly, you would create an email service node for this, like the one that by default available in the Eclipse editor. This video should help: http://vimeo.com/26126678.

We should probably add the Email and Log service nodes by default in the oryx designer, if no custom workitem definition configuration is present. I will see to add that for the next release.

[uvijayreddy657]

I have seen Email Node which is in the Eclipse Editor. This is the same feature which I am looking for. May be I am curious, in which release this node will be added in the Oryx designer.

Thanks.

[tsurdilovic]

Funny you ask as  I just committed this to designer couple days ago  - https://issues.jboss.org/browse/JBPM-3382

It is very easy to create those yourself now in Guvnor, just use the following .wid configuration:

import org.drools.process.core.datatype.impl.type.StringDataType;

[

  [

    "name" : "Email",

    "parameters" : [

      "From" : new StringDataType(),

      "To" : new StringDataType(),

      "Subject" : new StringDataType(),

      "Body" : new StringDataType()

    ],

    "displayName" : "Email",

    "icon" : "$protocol$://$host$/$subdomain$/rest/packages/$pkgName$/assets/defaultemailicon/binary"

  ],

  [

    "name" : "Log",

    "parameters" : [

      "Message" : new StringDataType()

    ],

    "displayName" : "Log",

    "icon" : "$protocol$://$host$/$subdomain$/rest/packages/$pkgName$/assets/defaultlogicon/binary"

  ]

]

and replace $protocol$, $host$, $subdomain$, $pkgName$ to your concrete values.

This will be available in the next designer release which should be available within next 3 weeks. If this is urgent for you, I can always craete an unofficial release which is based on master bits + this fix...let me know if you want that.

Hope this helps.

[uvijayreddy657]

Thank You Very much Tihomir.

It would really help me if can you can provide me the latest war with this fix.

[uvijayreddy657]

After creating an email node using WorkItem Defintion, trying to load the existing process the Oryx Designer is hanging up. Tested the same in multiple times. Below is the screenshot.

[tsurdilovic]

Typically when you see this, its a JavaScript error. Do you have FireBug installed to check what it is? Also paste your workitem configuration as most likely it contains something that is causing this problem.

Thanks.

[tsurdilovic]

>> It would really help me if can you can provide me the latest war with this fix. << Sorry I will do this as soon as possible. Currently working on a addition of a new feature so need to get master stable before I can create the unofficial war.

[uvijayreddy657]

Below is the WorkItem Definition which I used to create Email and Log Nodes as you Suggested Tihomir. I did not give value to icon.

import org.drools.process.core.datatype.impl.type.StringDataType;

[

  [

    "name" : "Email",

    "parameters" : [

        "From" : new StringDataType(),

        "To" : new StringDataType(),

        "Subject" : new StringDataType(),

    "Body" : new StringDataType()

    ],

    "displayName" : "Email",

    "icon" : ""

  ],

  [

    "name" : "Log",

    "parameters" : [

      "Message" : new StringDataType()

    ],

    "displayName" : "Log",

    "icon" : ""

  ]

]

[tsurdilovic]

This was a bug in the designer which caused a JavaScript error. Is fixed now (see https://issues.jboss.org/browse/JBPM-3393) and will be available in the next version. For now, please make sure that you have images for your workitems.

Hope this helps.
