By @VargaJoe

var crmcontactsall = this.Model.Items.Where(c => c.Type("RorWebCRMContact") && c.Path.StartsWith(company.Path)).ToList();

This worked in 7.0.2, but after upgrading to 7.1.1 it gives 0 results without an error. If we replace the 'startswith' term with 'InTree' (which is the recommended way anyway) it works correctly.

var crmcontactsall = this.Model.Items.Where(c => c.Type("RorWebCRMContact") && c.InTree(company.Path)).ToList();

@kavics: Has something changed related to this feature in the last few releases? Should this work?
@VargaJoe: please clarify the type of Model.Items, is that a list in a collection view (ascx)?

yes, the example code is from a ContentCollectionView

I cannot reproduce this bug so I would like to see/debug the actual solution. The ContentCollectionView.Model is a ContentCollectionViewModel (what a surprise). This object is generally an IQueryable that can wrap IEnumerable or ISnQueryable. This duality maybe can cause an error but I think this is not the case now.

I've managed to reproduce the bug with the following steps:

  • installed services and webpages with snadmin
  • changed the contentcollectionview to insert a few extra rows
var test = this.Model.Items.Where(c => c.Type("Page") && c.Path.StartsWith("/Root/Sites/Default_Site")).ToList();
var test2 = this.Model.Items.Where(c => c.Type("Page") && c.InTree("/Root/Sites/Default_Site")).ToList();

and duplicate the foreach to use these lists

  • created a page with a ContentCollectionportlet and set to query all the page with CurrentSite bindings and use the modified view
    (interestingly, when I set CustomRoot with /Root or /Root/Sites, the portlet does not give results, but with CustomRoot /Root/Sites/Default_Site does)

  • on the test page the first foreach shows nothing and the second shows the two pages (login and the test page)

  • some extra test

var test3 = SenseNet.ContentRepository.Content.All.Where(c => c.Type("Page") && c.Path.StartsWith("/Root/Sites/Default_Site")).ToList();
var test4 = SenseNet.ContentRepository.Content.All.Where(c => c.Type("Page") && c.InTree("/Root/Sites/Default_Site")).ToList();

With the same result (test3 nothing, test4 working).

I could try to reproduce this on a demo site if there is any.
