Reg:Workflow store

[Shantanu Puranik]

Hi 2 All,
    I am using OS Workflow framework for my application. I've a doubt regarding Workflow store.

 I would like to know what is the significance of [b]OS_CURRENTSTEP_PREV[/b] and [b]OS_HISTORYSTEP_PREV[/b] in Workflow. And if it so important, then why these tables are not included or mapped for SpringHibernateWorkflow Store.

Pl can anyone help me......

Thanks & Regards
Karthikeyan.

I am using SpringHibernateWorkfloeStore without these tables just fine. The AbstractHibernateWorkflowStore contains a note that previous steps are not persisted.

Perhaps Hani or Pat could shed some light on the purpose of the previous step.

Hi Samer,
       Thanks for ur reply.I am also using SpringHibernate Workflow store for my applicatin and i've no problem using it.But I'm curious to know why these previous step ID's are not persisted in hibernate.
             Also Samer, may i know what type of application you're using this workflow store whether its Enterprise application or for small application..because we've to double check it before using this workflow store.

One application is a manager self-service application allowing managers to make employee changes such as pay, job, reporting relationships, and transfers. The other application is to manage changes to and applications for purchase and expense credit cards.

I am also planning to update two other applications one for performance reviews and one for mass pay changes to use OSWorkflow in the near future.

What do you mean by double check it? Are you not confident that it is production ready?

you can overload the springhibernateworkflowstore to persient the two table your self if you need use the two tables in you application ,with this operatioin you must first mapping these table to each of class and add these to your hibernate configuration ,,then you can only do persisention in createNewCurrent ,and moveTohistory methods of springhibernateworkflowstore class!

Without keeping track of the previous steps there is no way to trace the path of execution to determine how the current step(s) came to be. At a glance it would seem that the history table would be enough. However that view does not take splitting into account. I was surprised to discover that the Hibernate storage mechanism included with OSWorkflow did not implement this behavior. I am currently trying to add it in as unobtrusively as possible but don't quite have it working yet. I'm not yet certain how much more time I'll be spending on it.
