Hi,
I have the following code in AMImpl. I encountered "oracle.jbo.InvalidOwnerException: JBO-25302: Component object SummaryVO2 has no parent" although i have called the code "this.addChild(prevVo);". If I commented out the code "prevVo.applyViewCriteria(vc);", will not encounter the error "oracle.jbo.InvalidOwnerException: JBO-25302". However, commenting out "prevVo.applyViewCriteria(vc);" is incorrect because I will need "SummaryVOCriteria" view criteria to exist in "SummaryVO2" vo: -

*public void createDynamicVOAndApplyVC (String str){*

*if(findViewObject("SummaryVO2") != null){*
SummaryVOImpl prevVo = (SummaryVOImpl)findViewObject("SummaryVO2");

ViewCriteria vc = prevVo.getViewCriteria("SummaryVOCriteria");
Variable [] var = prevVo.ensureVariableManager().getVariables();

ViewLinkImpl vl = (ViewLinkImpl)findViewLink("kanbanVL");
NamedObjectImpl parent = prevVo.getParent();
vl.remove();
prevVo.removeApplyViewCriteriaName("SummaryVOCriteria");
prevVo.remove();
prevVo = (SummaryVOImpl)this.createViewObjectFromQueryStmt("SummaryVO2", str,"model.SummaryVOImpl");

ViewObject master = findViewObject("SummaryVO2");
ViewObject detail = findViewObject("ekanbanVO2");

vl = (ViewLinkImpl)this.createViewLinkBetweenViewObjects("master_detail",
*"kanbanVL",*
findViewObject("SummaryVO2"),
*new AttributeDef[]{master.findAttributeDef("PULL_SEQUENCE_ID")},*
findViewObject("ekanbanVO2"),
*new AttributeDef[]{detail.findAttributeDef("PullSequenceId")},*
null);

prevVo.ensureVariableManager().addVariable(var[0]);
prevVo.ensureVariableManager().addVariable(var[1]);
prevVo.ensureVariableManager().getVariables();
prevVo.applyViewCriteria(vc);
this.addChild(prevVo);

*}*

*}*
