Need to implement validation on submission of rename if new name is already present

take a look at https://www.ptc.com/en/support/article/CS119050 

Hi @TP_10729144 

Do you use a wizard ? and Processor that do what you need?

If so use preProcess method to check if the name already exists in the system and return an error.

@Override
public FormResult preProcess(NmCommandBean nmCommandBean, List<ObjectBean> objectBeans) throws WTException
{
	FormResult formResult = super.preProcess(nmCommandBean,objectBeans);
	formResult.setStatus(FormProcessingStatus.FAILURE);
	return formResult;
}
