Re: {Spam?} CVS Update - 050627

Hi Sasa/all,

I downloaded everything from cvs yesterday and found that 
WfProcess.get_activities_in_state()was still not working. Here's what I 
have had to do to fix the problem:

1. Change DODSPersistenceManager.getActivitiesForProcess(String 
procId,String actState,SharkTransaction ti) as follows:

After this call: DOs = query.getDOArray();
add: for (int i=0; i<DOs.length; i++) {
                ((SharkDODSTransaction)ti)._read(DOs[i]);
        }
(otherwise iterator4type("class 
org.enhydra.shark.instancepersistence.data.ActivityDO") is always empty).

2. Change WfActivityIteratorWrapper.fillObjectList(SharkTransaction t) 
sort of like you said but slightly differently (to avoid 
ArrayStoreException):

Just before call to setObjectList(activities); add an extra else as 
follows:
else { // case:  !(qemod.equals(queryExpression))
        for (int i = 0; i < l.size(); i++) {
                   ActivityPersistenceInterface po = 
(ActivityPersistenceInterface) l.get(i);
                   activities.add(SharkEngineManager.getInstance()
                                .getObjectFactory()
                                .createActivityWrapper(userAuth,
                                            po.getProcessMgrName(),
                                            po.getProcessId(),
                                            po.getId()));
                }
}

I tested the above changes with the following code:

1. Get assignments as usual: WfAssignment[] assignments = 
sConn.getResourceObject().get_sequence_work_item(0);
2. Now test for wfProcess.get_activities_in_state:
for (int ii=0; ii<assignments.length; ii++) {
        String processKey = assignments[ii].activity().container().key();
        WfProcess sharkProcess = execAdmin.getProcess( processKey );
        log.debug("assignment " + ii + ": " + 
assignments[ii].activity().key() + ", " + 
assignments[ii].activity().state());

        //i have a notstarted-not-running assignment n my wf, so test 
WfActivityIterator.get_next_n_sequence( 0 ):

        WfActivityIterator activityIterator = 
 
sharkProcess.get_activities_in_state(SharkConstants.STATE_OPEN_NOT_RUNNING_NOT_STARTED);
        WfActivity[] sharkActivities = 
activityIterator.get_next_n_sequence( 0 );
        for (int i = 0; i < sharkActivities.length; i++) {
                result.add(sharkActivities[i]);
                log.debug("adding: " + sharkActivities[i].key() + ", " + 
sharkActivities[i].state());
               }
               log.debug("sharkActivities length is: " + 
sharkActivities.length);

}

Seemed to work ok with these changes.. Please let me know if the above 
changes seem to make sense to you.
Thanks!
Geeta

{Spam?} [shark] CVS Update - 050627






Hi,

the CVS is updated with some bug fixes:

- DODS stdcaches.jar fixed - it caused concurent exception errors (thanks 
to Roland Schimmack)
- SecurityManager now reads proper entry from Shark.conf (thanks to Geeta 
and Sebastian)
- DODS EventAudit and InstancePersistence managers fixed to support 
persisting of null variables on Oracle (thanks to Roland
Schimmack)
- WfActivityIterator and DODSPersistence manager fixed to properly 
retrieve activities in a certain state when using
WfProcess.get_activities_in_state() method (thanks to Geeta)
- BaseIteratorWrapper fixed not to throw null pointer exceptions when 
there is no expression set (thanks to Neville van Deventer)


probably this week, we'll have a bug fix release (mainly because the 
crucial bug in DODS jar file), so we will appreciate if you can
test this version, and give us a feedback if there are some more problems.

Regards,
Sasa.
