Support "parentpanel" in expression for nested dynamic panels

If there is a nested dynamic panel (dynamic panel inside another dynamic panel), then to access values in expression from the parent panel can by using “parentpanel” prefix. Here is the JSON example. “child_question1” becomes visible when an user set any value into checkbox_root question and child_question2 shows choices that selected in checkbox_root.

{
      elements: [
        {
          type: "paneldynamic",
          name: "rootPanel",
          panelCount: 1,
          templateElements: [
            {
              type: "checkbox",
              name: "checkbox_root",
              choices: ["item1", "item2", "item3"],
            },
            {
              type: "paneldynamic",
              name: "childPanel",
              minPanelCount: 1,
              templateElements: [
                {
                  type: "text",
                  name: "child_question1",
                 visibleIf: "{parentpanel.checkbox_root} notempty"
                },
                {
                  type: "checkbox",
                  name: "child_question2",
                  hideIfChoicesEmpty: true,
                  choicesVisibleIf: "{parentpanel.checkbox_root} contains {item}",
                  choices: ["item1", "item2", "item3"],
                }
              ]
            }
          ]
        }
      ]
    }

@masciugo I have fixed the issue by the commit above. {panel.region} will work for your example.

Thank you, Andrew

@masciugo In your case the following example should work. Unfortunately, it doesn’t. I will take a look.

Thank you, Andrew
