Changing Phase in Validation Script

[Former Member]

Hi guys,

I would like to change the phase in the Validation Script.When i added a script to change phase in validation target, it seems like the valistion script is run many times. I known it from the log file . So i'm not sure that the script is run multiple times or All document run the validation script again. Please see the log below. The first one are occured many times (more than 20 times) then the secound one come many times as well.

I think the problem probably is when the document is changed the phase the validation script is run again. It may cause StackOverFlow exception. How can i handle this case?

Below is the code in validation script :

//'*** IMPORTS ************************************************************
import com.frictionless.api.ibean.IBeanIfc;
import com.frictionless.api.ibean.CollectionIfc; 
import com.frictionless.api.common.platform.IapiSessionContextIfc; 
import com.frictionless.api.doccommon; 
import com.frictionless.api.projects.ProjectIBeanHomeIfc;
import com.frictionless.api.common.types.TypeFactory;
import com.frictionless.api.common.types;
import com.frictionless.api.ibean.HighLevelBizDocIBeanIfc;
import java.math.BigDecimal;
import com.frictionless.api.ibean; 
import com.frictionless.api.common.platform.IapiDbHandleIfc; 
import com.frictionless.api.ibean.ExtensionCollectionIfc;
//'*** END OF IMPORTS **************************************************

exception = new ApplicationException(session);
projectHome=IBeanHomeLocator.lookup(session, ProjectIBeanHomeIfc.sHOME_NAME);

log = Logger.createLogMessage(session);
log.setMethod("Project Validation");

logInfo(msg){
	log.setLogMessage(msg);
	Logger.info(log);
}

if(doc.isObjectAccessModeView()){
    projectHome.upgradeToEdit(doc);
}

logInfo("------- Start Project Validation ------------ ");
docTypeRef = doc.getDocTypeReference();
docTypeHome = IBeanHomeLocator.lookup(session,docTypeRef );
docType = docTypeHome.find(docTypeRef);
docTypeName = docType.getDisplayName();

logInfo("Var docTypeName : "+ docTypeName);

currentPhaseRef = doc.getCurrentPhase();
logInfo("Var currentPhaseRef : "+ currentPhaseRef);
currentPhaseName = null;

if(hasValue(currentPhaseRef)){
	currentPhase = IBeanHomeLocator.lookup(session,currentPhaseRef ).find(currentPhaseRef);
	currentPhaseName = currentPhase.getDisplayName();
}


logInfo("Var currentPhaseName : "+ currentPhaseName);

if(docTypeName.equals("Project Approval flow") @and !hasValue(currentPhaseName)){
	logInfo("Change phase to Draft for "+ doc.getDocumentId());
	doc.getIBeanHomeIfc().upgradeToEdit(doc); 
	doc.getIBeanHomeIfc().changePhase(doc,"Draft");	
	//exception.chainAtEnd(doc.createApplicationException("CURR_CONFIG_PHASE","Please change phase"));
}

if(!hasValue(doc.getDocumentDescription())){
	exception.chainAtEnd(doc.createApplicationException("DOCUMENT_DESCRIPTION","Please enter Document Description"));
}


//'*************************************************************************
if(exception.getChain() != null){
    throw exception.getChain();
}
//'*** END *****************************************************************

Hi,

ChangePhase() issues an implicit save and that should be the root cause of the stack overflow issue.

Validation call hapens before the save and in the mentioned validation script, a change phase is done, which issues an implicit save, which internally calls the validate script again and that goes in recursion infinitely.

Would suggest to look at other scripting exists (e.g. postCreate) considering the post Script behavior..

Thanks,

Baski

Thank you so much for your response Baski,

The 'PostCreate' script is excuted only 1 time when the document has been saved for first time,right?

Thank you in advance,
