Hello all,

I want to pass the List values of an object to the other Visualforce page using a query. Since we cannot pass list as parameter to other page i am using

public PageReference DisplayDetails() {
      
        PageReference reRend = new PageReference('/apex/wrapperCustomObjpage2');
        reRend.setRedirect(false);
        return reRend;
       
    }

But the variables in the controller were reintializing after entering into the other page. I am not able to display the data into pageblocktable. Could any one suggest me the best approach
