Playing with PersistableAdapter

I am starting to play with the new "PersistableAdapter" API, I am noob to java too.


My question is, how to update an attribute of the primaryBusinessObject using a workflow expression or transition?


If I try the code below directly I will receive an error cause the PBO was not checked out before running the code, but If I checkout the PBO before running it I receive the error stating that "1.1 is the original version of a working copy and cannot be modified"


Obviously I am missing something here... Any help?



com.ptc.core.lwc.server.PersistableAdapter obj = new com.ptc.core.lwc.server.PersistableAdapter(primaryBusinessObject,null,null,new com.ptc.core.meta.common.UpdateOperationIdentifier());




newValue);


obj.persist();

Try the following:

- Check out the object
- Get the "working copy" of primary business object and pass it to the
method (PersistableAdapter)

- Check in the object once you modify your object


*Note:*

- You can use
"wt.sandbox.SandboxHelper.service.getWorkingCopyOf((wt.vc.Versioned)primaryBusinessObject)"
to get working copy of primary business object. Based on my knowledge
"getWorkingCopy" API is deprecated in 10.X

- Alternately, check if you can use class "WorkInProgressHelper" to get
working copy.

This may be what you are looking for. Use this class instead. I vaguely remember that there may be an even newer class for this in 10.2 but you'd have to look at the Java doc's for that info. I've used this a lot in workflows. Works really well and doesn't require any checkout.

I guess there is a new class that helps us do this. I've done this in the past with a custom webject but this is so much nicer. I haven't used it yet but it is from PTC's documentation on the API.

Just for reference of others with the same need, the code for updating an
attribute in a workflow expression/transition using version 10.2 is:



Object object=primaryBusinessObject;

if(object.getClass().isAssignableFrom(wt.doc.WTDocument.class)){

wt.doc.WTDocument doc=(wt.doc.WTDocument)primaryBusinessObject;

doc = (wt.doc.WTDocument)
wt.vc.wip.WorkInProgressHelper.service.checkout(doc,wt.vc.wip.WorkInProgress
Helper.service.getCheckoutFolder(), ").getWorkingCopy();

com.ptc.core.lwc.server.PersistableAdapter obj = new
com.ptc.core.lwc.server.PersistableAdapter(doc,null,java.util.Locale.getDefa
ult(),new com.ptc.core.meta.common.UpdateOperationIdentifier());

obj.load("Attr1");

obj.set("Attr1", "NEW VALUE");

doc=(wt.doc.WTDocument)obj.apply();

wt.fc.PersistenceHelper.manager.modify(doc);

wt.vc.wip.WorkInProgressHelper.service.checkin(doc, null);

}





Estou a disposição para qualquer esclarecimento.
