Possible bug in Page inputfield?

[steveooo]

Hello guys,

I have a Page field for my own global media gallery. When I select one page, I get following PageArray via the API:

object(ProcessWire\PageArray)#287 (7) {
  ["hooks"]=>
  array(2) {
    ["PageArray::render"]=>
    string(60) "MarkupPageArray->renderPageArray() in MarkupPageArray.module"
    ["PageArray::renderPager"]=>
    string(56) "MarkupPageArray->renderPager() in MarkupPageArray.module"
  }
  ["count"]=>
  int(3)
  ["items"]=>
  array(3) {
    [0]=>
    string(29) "/files/unpublished/"
    [1]=>
    string(25) "/files/animals/"
    [2]=>
    string(23) "/files/sloth/"
  }
  ["total"]=>
  int(3)
  ["start"]=>
  int(0)
  ["limit"]=>
  int(0)
  ["selectors"]=>
  string(0) ""
}

So I select 1 Page and get 3 Pages in return? How can this happen? From the interface here, everything looked fine:

Here is the stuff that created the field (if needed):

$data['getFileField'] = new Field();
$data['getFileField']->type = $this->modules->get('FieldtypePage');
$data['getFileField']->name = 'fooBar';
$data['getFileField']->label = $this->_('File select');
$data['getFileField']->parent_id = $files['page']->id;
$data['getFileField']->inputfield = 'InputfieldPageListSelect';
$data['getFileField']->labelFieldName = 'title';
$data['getFileField']->allowUnpub = 1;
$data['getFileField']->description = $this->_('Select one file or folder. If folder is selected, the first file inside of it is used.');
$data['getFileField']->icon = 'file-o';
$data['getFileField']->save();

Is this a bug?

EDIT:

Now I am pretty sure it is a bug in PW (3.0.10):

If I select a page via the Page field, the PageArray is only with this page.

If I change the page via the Page field (and save), I get the old one plus the new one.

So somehow it does not get reseted on new selection.

Maybe you selected the wrong input field type?

[steveooo]

No, sorry. Double checked that

If you only want to allow one page you should also configure to only allow single page. Currently you have a single select but the field is multiple.

[steveooo]

The thing is: Even if I allow the "folder" page that has children (files or another folder), the Page select would give me the children. But It somehow remembers the old selection and does only add to it. Maybe some caching thing even if I disabled all caching?

Any idea how I can test it better to find the bug?

EDIT:

When I select a single page with no children, the Page select also does not work...

The behavior is like this:

If I change my selection, the old one does not get removed. All previous selections still appear as items in the resulted PageArray.

This very seems like a bug. Does it help for you guys (and girls) when I upload a screencast of the bug?

Hello guys,

hope you all had a great weekend!

I made a short screencast that shows the bug and its behavior. Maybe this helps anyone for a fix or for a solution (maybe I am doing something wrong?).

The bug is that it should have replaced the Sky-1.jpg item instead of only adding the new one.

Here is the video:

Thanks for your answers!

I don't see where you set:

$field->derefAsPage == FieldtypePage::derefAsPageOrNullPage;

When you don't set it it will store as a PageArray. 

[steveooo]

Thank you! That was the problem!

But is it still a bug? I thought that using PageArray output for the Page field, I get (when only one page is selectable) a PageArray with only one item in it. Kind of return $page vs return array($page)..

But thanks again!

[Martijn Geerts]

Not a bug, it just how it is. The 1 page is forced by the Inputfield, not the Fieldtype.
