eXpand.Search

[CWolffIF]

Hi Tolis,

is there a documentation about the eXpand.Search Modul (from the eXpand.System Modul)? I like to understand the possibilities of the Modul and the paramters to set in den Moduleditor.

In one of my projects (but only in one) I go an Error when using the Search-Button from the DetailView. But I don´t really understand the options to set.

iXISXRM.Win.exe Error: 0 : 05.01.19 14:04:15.611 ================================================================================
The error occurred:

Type:       NullReferenceException
Message:    Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

I understand the importance of some basic at least documentation and examples. So at the moment I am focusing or packaging the framework in smaller nuggets where you will find what you need see the Packages project. You welcome to participate if you like.

Now digging the source on this exception first it leads to

eXpand/Xpand/Xpand.ExpressApp/Xpand.ExpressApp.Win/SystemModule/SearchFromDetailViewController.cs

Line 16 in 84e8e3e

var propertyEditor = ((DetailView)View).GetItems<PropertyEditor>().Single(editor => editor.PropertyName == SearchAbleMemberInfos.ToList()[0].Name);

where the only possible NullReference could be in SearchAbleMemberInfos which is declared in base class and assigned at

eXpand/Xpand/Xpand.ExpressApp/Xpand.ExpressApp/SystemModule/Search/SearchFromDetailViewController.cs

Lines 33 to 34 in 84e8e3e

	_searchAbleMemberInfos = detailView.Model.Items.OfType<IModelPropertyEditorSearchMode>().Where(
	mode => mode.SearchMemberMode == SearchMemberMode.Include).Select(searchMode => View.ObjectTypeInfo.FindMember(((IModelPropertyEditor)searchMode).ModelMember.Name));

This line tells us the the View.ObjectTypeInfo.FindMember returns null, so you need to question if this check holds
mode.SearchMemberMode == SearchMemberMode.Include
