Open Source Document Management System | OpenKM

Hi, We are going to create a file workflow. we need to popup a dialogbox after a task node. We want to develop this diaogbox like the AboutPopup. So we tested this idea like this in the trasition action after a task node. But, the system reply the error: callbackRunProcessDefinition. we didn't know why the dialogbox can't be initialized and showed in this workflow.

Consider UI works from OpenKM not from the workflow engine point of view. Each task is mapped with a group of form elements, and there's no relation between transaction and form elements. I think you should consider adding in the middle another task to shown form elements.

Thank you for your suggestion. To be extend your idea can meet our requirement,but we neet a dialog box in some respect. we will continue to research some way to realize it.

Another aproach might be in the UI create new object in form elements for it. But I do not suggest going in this direction, I think might be very very complex and there's a high % of possible failure.

Another suggestion is using the WF API ( rest web services ) and from there build your own user interface, that probably will be a better solution for you.

Finally if you have a workflow problem, you can choose another WF engine ( outside OpenKM ), use it in the front and OpenKM in this scenario will be an slave ( only for storing an retrieving documents ). I'm talking about a webservices integration.
