Throw Warning Message in Custom Listener

marshall_brock — Tue, 26 Aug 2025 23:00:49 GMT

Version: Windchill 13.0

Description:

We have customized a PRE_WORKSPACE_CHECKIN listener to process an attachment file and populate attributes on the associated CAD document during the check-in process. It works great, but sometimes users forget to add the attachment, which results in none of the necessary attributes being populated. Is there a way to throw a warning (or error that can then be bypassed) to the user during check-in to tell them they are missing the attachment? Ideally I would like to call this in the custom listener.

public void notifyVetoableEvent(Object event) throws Exception{ if(!(event instanceof KeyedEvent)) { return; } //Object target = ((KeyedEvent) event).getEventTarget(); Object type = ((KeyedEvent) event).getEventType(); if(type.equals(EPMWorkspaceManagerEvent.PRE_WORKSPACE_CHECKIN)) { EPMWorkspaceManagerEvent wsEvent = (EPMWorkspaceManagerEvent) event; WTSet workingCopies = ((WTKeyedMap) ((EPMWorkspaceManagerEvent) event).getWIPMap()).wtKeySet(); WTCollection epmDocs = workingCopies.subCollection(EPMDocument.class); Iterator docItr = epmDocs.persistableIterator(EPMDocument.class, true); while (docItr.hasNext()) { EPMDocument epmDoc = (EPMDocument) docItr.next(); wt.fc.Persistable pers = (wt.fc.Persistable) epmDoc; com.ptc.core.meta.common.TypeIdentifier tiObj = wt.type.ClientTypedUtility.getTypeIdentifier(pers); String objType = tiObj.toString(); if( objType.endsWith("VOCCADDocument")) { QCheckHelper qChecker = new QCheckHelper(epmDoc); // WARNING THROW SHOULD HAPPEN HERE, PSUEDO CODE INCLUDED FOR REFERENCE if (qChecker.hasQCFile() == false) { new FeedBackMessage("Missing QC File! Continue check-in without adding?"); // IF USER CLICKS "PROCEED" BELOW CODE EXECUTES AND POPULATES WITH BLANK VALUES // IF USER CLICKS "CANCEL" THE CHECK-IN IS ABORTED } // END OF PSUEDO CODE, REMAINING CODE WORKS AS EXPECTED Map<String, String> attr_value_map = new HashMap<String, String>(7); attr_value_map.put("QC_ACTACTION", qChecker.getActAction()); attr_value_map.put("QC_ASSESSMENT", qChecker.getAssessment()); attr_value_map.put("QC_CHECK_DATE", qChecker.getCheckDate()); attr_value_map.put("QC_CHECK_TIME", qChecker.getCheckTime()); attr_value_map.put("QC_CHECK_USER", qChecker.getCheckUser()); attr_value_map.put("QC_PROFILE_NAME", qChecker.getProfileName()); WTKeyedMap keyed_map = new WTKeyedHashMap(1); keyed_map.put(epmDoc, attr_value_map); EPMWorkspaceHelper.manager.setAttributes(wsEvent.getWorkspace() , keyed_map); } } } }

Related to your other linked message, I did this on a rename listener by throwing a WTException

throw new WTException("Rename for Part " + master.getNumber() + " rejected since name length exceeds 40 characters for SAP");

though WTException is a hard no bypass way which might not work in your situation.

Thanks for the response, but you are correct that this would produce a hard error with no bypass which is undesirable in my situation. This is what I plan to use as a last resort. I was hoping to find a solution using either the conflict manager (ConflictElement/Resolution API) or FeedbackMessage, but I'm not very familiar with either.

Hi @marshall_brock

As I wrote, it it more complicated.

here is an example how to create message with options for the error message

ArrayList<String> incorrectMessages = new ArrayList<>(); incorrectMessages.add("Delete WTP case ProcessPlan error!"); WTPDeleteMessage errorTitle = new WTPDeleteMessage("!!!! WARNING !!!!: ", "35", new Object[]{incorrectMessages}); ConflictType cType = WTPDeleteConflictType.DELETE_WTP_NOT_ALLOWED; ResolutionType rType = ResolutionType.RETRY; ResolutionType sType = ResolutionType.SKIP; ConflictElement conflictElement = new ConflictElement(cType, new ResolutionType[]{sType, rType}, sType, errorTitle, wtp); ConflictException conflict = new ConflictException(new ConflictElement[]{conflictElement}); ResolutionType resolutionList = ConflictServerHelper.getResolution(wtp, cType); // VERY IMPORTANT API TO GET RESOLUTION OPTIONS if (resolutionList == null) { throw conflict; } else { String option = resolutionList.getDisplay(Locale.US); if (option.equals("Retry")) { logger.info(String.format("WTPart linked to Process Plan is deleted. WTPart: %s, Process Plan: %s User %s", wtp.getNumber(), plan.getNumber(), user.getName())); } else { throw conflict; } }

API to override conflict on EPMWorkspaceHelper.manager.checkout

You have to create own conflict type

In my example I used own class WTPDeleteConflictType

How to create RbInfo file

How to create a drop down list in a workflow instance task detail page of Windchill PDMLink

Also I created own WTPDeleteMessage based on WTMessage.class

Hope this can help you.

Thank you for the response with an example! I will give this a try.

I think we can use FormProcessingStatus.NON_FATAL_ERROR. This gives warning and proceeds with rest of the tasks.

Previously I had the same requirement and achieved the result with this.

Do you have any examples of how you achieved this?
