indexing and logic inside a dynamic panel

Are you requesting a feature, reporting a bug or asking a question?

Questions I’m using a dynamic panel with 3 widgets inside. I want the user to fill these widgets one by one in a fixed order so I want to hide them first. As each tab is independent, I need to retrieve the tab index each time.

How can I get the current panel tab index to write the logic? Can this be done directly in the survey editor? Can we also add some logic to the “add new” button so it is disabled until we ask all questions in the current tab?

Example: {mypanel[currentIndex].question1} notempty -> mypanel[currentIndex].question2 visible

What is the current behavior?

What is the expected behavior?

How would you reproduce the current behavior (if this is a bug)?

Provide the test code and the tested page URL (if applicable)

For anyone stuck on this issue, I was struggling for a while because of an ambiguity in @andrewtelnov linked example:

var json = {
   "textUpdateMode": "onTyping",
 "pages": [
  {
   "name": "page1",
   "elements": [
    {
     "type": "paneldynamic",
     "name": "panel",
     "panelCount": 1,
     "templateElements": [
      {
       "type": "text",
       "name": "question1"
      },
      {
       "type": "text",
       "name": "question2",
       "visibleIf": "{panel.question1} notempty"
      },
      {
       "type": "text",
       "name": "question3",
       "visibleIf": "{panel.question1} notempty and {panel.question2} notempty"
      }
     ]
    }
   ]
  }
 ]
};

Because the dynamic panel happens to be named "panel", it looks like the logic must be written as {${panelName}.${questionName}}, when in fact panel is a keyword in the logic expression for the current dynamic panel's instance. In other words, even if your dynamic panel is named opinions, the logic will be panel.question1 and not opinions.question1.

Perfect this is what I was looking for.

Thank you.
