Fixed version (ground truth):
@Override protected void initialize(){
  getConnection().setInputModel(false);
  this.treePopulator=new TreePopulator(availableJSONTree);
  if (getConnection().getJSONFilePath() != null) {
    jsonFilePath.setText(getConnection().getJSONFilePath().replace("String_Node_Str","String_Node_Str"));
    checkFieldsValue();
    String jsonXmlPath=jsonFilePath.getText();
    if (isContextMode()) {
      ContextType contextType=ConnectionContextHelper.getContextTypeForContextMode(connectionItem.getConnection());
      jsonXmlPath=TalendQuoteUtils.removeQuotes(ConnectionContextHelper.getOriginalValue(contextType,jsonFilePath.getText()));
    }
    if (!new File(jsonXmlPath).exists() && getConnection().getFileContent() != null && getConnection().getFileContent().length > 0) {
      initFileContent();
      jsonXmlPath=tempJSONPath;
    }
    if (JSONFileOutputStep1Form.this.tempPath == null) {
      if (jsonXmlPath != null && !jsonXmlPath.equals("String_Node_Str")) {
        JSONFileOutputStep1Form.this.tempPath=JSONUtil.changeJsonToXml(jsonXmlPath);
      }
 else {
        JSONFileOutputStep1Form.this.tempPath="String_Node_Str";
      }
    }
    File file=new File(JSONFileOutputStep1Form.this.tempPath);
    if (file.exists()) {
      valid=this.treePopulator.populateTree(JSONFileOutputStep1Form.this.tempPath,treeNode);
    }
