ECN set state on certain changeables

[ColinBull]

Hi guys.

Just want some tips here. I want to use an expression in the ECN workflow

to set a state of INWORK for EPM and Documents only in the changeables in the ECN workflow. I have tried some code but i get exception errors in the robot it is trying to run highlighted in BOLD. Can anyone help?

//Set State of Main Object (Document or Part) back to Inwork.
wt.fc.QueryResult resultingChangeableQr = wt.change2.ChangeHelper2.service.getChangeablesAfter((wt.change2.ChangeActivityIfc) primaryBusinessObject);
System.out.println("(MM) ##### Total Doc Found:-" + resultingChangeableQr.size() );
while( resultingChangeableQr.hasMoreElements() )
{
java.lang.Object obj = resultingChangeableQr.nextElement();
if(obj instanceof wt.doc.WTDocument)
{
System.out.println("(CB) Document Found");
wt.fc.Persistable changeable = (wt.fc.Persistable) resultingChangeableQr.nextElement();
changeable = (wt.fc.Persistable) wt.lifecycle.LifeCycleHelper.service.setLifeCycleState( (wt.lifecycle.LifeCycleManaged)changeable, wt.lifecycle.State.INWORK );
}
if(obj instanceof wt.epm.EPMDocument)
{
System.out.println("(CB) CAD Document Found");
// wt.fc.Persistable changeable = (wt.fc.Persistable) resultingChangeableQr.nextElement();
// changeable = (wt.fc.Persistable) wt.lifecycle.LifeCycleHelper.service.setLifeCycleState( (wt.lifecycle.LifeCycleManaged)changeable, wt.lifecycle.State.INWORK );
}
} //End of While
System.out.println("(MM) ##### Executed:-" + resultingChangeableQr.size() );

Hi Colin



You are using nextElement() once for checking the instance and second time
before setting the state.

wt.fc.Persistable changeable = (wt.fc.Persistable)
resultingChangeableQr.nextElement();
should be coded as

wt.fc.Persistable changeable = (wt.fc.Persistable) obj;



Just to improve the code, please try to use WTObject instead of obj and
LifeCycleManaged instead of Persistable. And as you set the same state for
both doc and cad, I am unsure why check the instanceof before setting the
state. And try to use helper classes from the expression robot instead of
entire java code inside expression robot. This will be handy when you go for
upgrades(major as well as MORs).



Thank you and have a great time.

Colin,

Here's a class file that I think will do something very similar to what
you need. See the method, setResultingItemsState(),

Pass this method a ChangeNotice object and it will:

Query it for the ChangeActivity.

Once found, the ChangeActivity is queried for Resulting Items for a
WTDocument. In our process the WTDocument is the object whose state is
used for the target state for the other Resulting Items objects so we
first find the WTDoc on the Resulting Items and then get its state.

Next we reset the CA query and go thru it again. Any object that is not a
WTDoc will then have it's state set to match the WTDoc. If that object is
a WTPart it too is queried for EPMDocs. Any associated EPMDoc whose
number (less extension - .prt, .asm, etc) and Version match the WTPart
also have their states set to match the WTDocument's state.

Hope this helps

David
