Drools Guvnor problem

[paulcoronel]

Hello,

I have integrated drools-guvnor with my business application (i use Seam framework). The StandaloneEditorServlet is used  to view and edit BPMN processes. However I have problems when saving processes. The first time that i save a process, it is saved successfully, after making changes to the process i try save again,  but the editor application shows the following error:

Unable to save this asset, as it has been recently updated by [Administrator]

Can you help with some solution to this problem?

Thanks in advance

I'm also integrating Guvnor with my web application and I'm experiencing the same problem you have. What you would need to do is to refresh the iframe where Guvnor is whenever you save the process. The problem is that right now, there is no way to add some kind of listener to Guvnor's save button when you are editing a process.

I will try to add this functionality into Guvnor soon.

Best Regards,

Thank you Esteban, I'll be waiting for your solution

I have created an issue for this problem: https://issues.jboss.org/browse/GUVNOR-1774

[eaa]

And this is the pull request: https://github.com/droolsjbpm/guvnor/pull/28

Let's wait and see if drools' team apply it.

What I did was basically to add 2 new hook function in JS:

registerBeforeSaveAllButtonCallbackFunction() and registerAfterSaveAllButtonCallbackFunction(). Using them, you can attach your own listeners to, for example, refresh the iframe after the process as been saved.

Hi,

to avoid this problem

Is there any way to save the  bpmn2 process, from my own save button?

Drools Guvnor does this

Thanks in advance

Yes, but it would involve some trickery:

1) First you have to get the JSON representation of the process via JavaScript:

window.frames[X].ORYX.EDITOR.getSerializedJSON()

where X is the number of the frame in your doc

2) Pass the JSON to designer to get it to convert it to BPMN2 (post):

localhost:8080/designer/uuidRepository?profile=jbpm&action=toXML&data=<YOUR JSON HERE>&pp=

3) Use the Guvnor rest api to create a new asset with its source being the BPMN2 you got back from Designer:

see this class as example on that...https://github.com/tsurdilo/process-designer/blob/master/src/main/java/com/intalio/web/server/TaskFormsServlet.java

Hope this helps

Thanks in advance

Designer deffers creation of new assets and saving to Guvnor as that is the asset repository. For some reason I think this blog post will be
