Single-Select Matrix ignores `hideIfRowsEmpty: true` if a `visibleIf` expression evaluates to `true`

[phuongvannguyen]

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

What is the current behavior? When I set a matrix Q3 with 'Hide the question if it has no rows"= True, row visible if Q2 = 'abc' and Q3 is visible if Q1 = yes then when I choose Q1 = No and input 'abc' for Q2--> Q3 is shown despite of the condition Q3 is visible if Q1 = yes.

What is the expected behavior? The expectation in this case is Q3 is not shown. Q3 is shown only if when Q1 = Yes and it has rows

Below is my test on online demo

{
"logoPosition": "right",
"pages": [
{
"name": "page1",
"elements": [
{
"type": "boolean",
"name": "question1",
"title": "Q1"
},
{
"type": "text",
"name": "question2",
"title": "Q2"
},
{
"type": "matrix",
"name": "question3",
"visibleIf": "{question1} = true",
"title": "Q3",
"columns": [
"Column 1",
"Column 2",
"Column 3"
],
"rows": [
{
"value": "Row 1",
"visibleIf": "{question2} = 'abc'"
},
"Row 2"
],
"hideIfRowsEmpty": true
}
]
}
]
}

Hello, Thank you for sharing a demo. In your survey configuration, Q3 has Row 2 which always appears regardless of confitional logic.

Would you please elaborate on your end goal?

To our developers: @andrewtelnov, when a matrix defines two visibility conditions (visibleIf and hideIfRowsEmpty: true), a matrix appears even though its rows are invisible. Please consider this demo: View Plunker.

{
 "logoPosition": "right",
 "pages": [
  {
   "name": "page1",
   "elements": [
    {
     "type": "boolean",
     "name": "question1",
     "title": "Q1"
    },
    {
     "type": "text",
     "name": "question2",
     "title": "Q2"
    },
    {
     "type": "matrix",
     "name": "question3",
     "visibleIf": "{question1} = true",
     "title": "Q3",
     "columns": [
      "Column 1",
      "Column 2",
      "Column 3"
     ],
     "rows": [
      {
       "value": "Row 1",
       "visibleIf": "{question2} = 'abc'"
      },
      {
       "value": "Row 2",
       "visibleIf": "{question2} = 'abc'"
      }
     ],
     "hideIfRowsEmpty": true
    }
   ]
  }
 ]
}

Expected behavior: a matrix doesn't appear unless a row becomes visible.

hi Jane, my expectation is Q3 will be shown only if when Q1 = Yes and it has rows
