Why business component does not support generics method parameter

Question

Hi Folks,
I have created a business component and in this business component I have added a public method which takes a parameter - List of map (Like List<Map<String, String>> inputListOfMap). Now when I try to run the artifacts for this business component it gives an error
ERROR
com.splwg.shared.common.LoggedException: No method declaration for createListElements found matching argument types [List, Element, String, String] with pattern public\s+(final\s+)?(<[^>]*>\s+)?([\w\.]+)\s*(<[\w<>,\s\.]+>)?\s+createListElements\s*\(\s*((\w*\.)+)?(List)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(Element)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(String)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(String)(\<[^\>]*\>)?\s+\w+\s*\)\s*(throws [^\{]+\s*)?[;\{]
After checking the spl-tool2.2.0 jar class JavaSourceFile.java i am guessing that such method parameters are not supported. It compiles well if its a simple Map or List. Also works fine if I make the method as private. But in this case I cannot use this method from any other class... which I don't want.
it would be great help if anyone can suggest what needs to be done to overcome this issue
Following is the method of Business Component
public void createListElements(List<Map<String, String>> inputListOfMap, Element sourceElement, String groupName, String listElementName) {
          logger.info("createListElements ");
          Element groupElement = null;
          Element listElement = null;
          if(!isBlankOrNull(groupName)){
               groupElement = sourceElement.addElement(groupName);
          if(notNull(inputListOfMap) && inputListOfMap.size()>0){
               for (Map<String, String> inputMap : inputListOfMap) {
                    //If group name is provided then put the list element will be within the group element else within the bill element
                    if(notNull(groupElement))
                         listElement = groupElement.addElement(listElementName);
                    else
                         listElement = sourceElement.addElement(listElementName);     
                    for (Map.Entry<String, String> mapEntry : inputMap.entrySet()) {
                         String elementName = mapEntry.getKey();
                         String elementValue = mapEntry.getValue();
                         if(notBlank(elementName) && notBlank(elementValue)){
                              listElement.addElement(elementName).addText(elementValue);
     }

Hi Victor,
the issue is that the archive pool in your NWDS is not set up properly. Could you check the configuration of the development configuration? I guess you are developing in Local Development, right? Please check in the "Component Browser" that the two Software Components "NWMCLIENT" and "XOCA" are present and contain some DCs inside them. If this is not true, than something went wrong with your setup of the IDE. The modifications of the default.confdef are most likely not right.
Please come back to me if you don´t know how to proceed.
Regards,
Stefan
