Issue description

Trying to open a detailpage ends in ‚no items found‘ all the time.

Steps to reproduce

1. set auto_item and Enable folder URLs in Settings to true
2. create 2 pages

• listpage
• detailpage

3. Create Metamodel with

• Attributes
  Name [text]
  Alias [alias] (generated via Name-field)
• Filter: testfilter
  Simple Lookup on attribute alias (URL-Paramerter: auto_item)
• render: testrender
  jumpTo : detailpage,
  Filter: testfilter
  Attributes: name and alias

4. Create some TestItems e.g. detailItem_1 and detailItem_2
5. add MM-List to listpage with no filter and render-settings: testrender
   => ItemList is showing up in FE with detail-link (link is /test/referenz-test/detailitem_1.html e.g. /test/referenz-test/detailitem_2.html)
6. add MM-List to detailpage with filter testfilter and render-settings testrender

Describe the behaviour of the application

Now click on detail-link of an detailItem on listpage => detailpage (e.g. URL: .../test/referenz-test/detailitem_1.html) is loaded with message 'no items found'

I tried to find the reason and came up to class ItemList in MM core,
function setFilterParameters($arrPresets, $arrValues)
dumping $arrValues I get an array like this:

array:2 [▼
"auto_item" => "test"
"referenz-test" => "detailitem_1"
]
So the value of auto_item is ‚test‘ and not ‚detailItem_1‘. That‘s the reason why I get an ‚item not found‘ I guess because there is no item with alias 'test'.

Describe the expected behaviour of the application

loading detailpage and showing data from detaiItem_1

I need more information on your setup.

1. What are the page aliases?
2. What part in the above URLs is originating from where.
3. Are folder URLs in use?

Can you please enhance above recreation steps with the page structure setup (page aliases at minimum).

[JoT2]

Sorry for the delay.
Page and Item Aliasses

1. List page (first level) name: Test, alias: test
2. Detail page (second level) name: Referenz-TEST, alias: test/referenz-test

Item Aliasses
name: detailItem_1, alias: detailItem_1
name: detailItem_2, alias: detailItem_2

on listpage (test.html) :
mmList (no filter):

Name:
detailItem_2
Alias:
detailitem_2
Details (jumpTo: test/referenz-test/detailitem_2.html)

Name:
detailItem_1
Alias:
detailitem_1
Details (jumpTo: test/referenz-test/detailitem_1.html)

on detailpage (referenz-test)
mmList (filter: Simple lookup, Attribute: Alias, URL parameter: auto_item )
=> There are no items matching your search.

Folder URLs in Use: yes

I hope this helps.

Maybe another extension is guilty...
