CrossSiteLookup for external List / BDC / BCS
Hi,
i've allready ask this question in the past, but maybe there is still a way to achive this?
viewtopic.php?f=5&t=2007&p=6327&hilit=e ... list#p6327
I'm able to provision the CrossSite-Lookup via JavaScript as a Website-Column.
If i define it as a normal Lookup column, to point to a external List, i'm able to create a normal CrossSiteLookup field. I can search for items in the external list. But i cant save the value.
In the Screenshot "CrossSiteLookup_ExternalData_Lookup.png" you see the lookup with BdcIdentity as Lookup-Column and "Titel" as additional value.
The field schema looks like this:
If i defnie it as a normal BusinessData column, but with the csl for crosssitelookup as JSLink, it dosnt render and im getting this error:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

The schema for this field looks like this:

Dear ragesoft,
Sadly, I do not think it is fully possible. There might be a way, but we did not manage to do it. If you do manage - please, let us know!

Hi Nikita,
what is a good starting point to realize a custom CSL for external Lookup fields?
My approche to overwrite the schema donst work until now. If i place the field inside a SPForm it also crashs the edit-form with a message "webpart page cannot be displayed"....
So, can i create somethink like a custom display template and reuse the init method of the crosssitelookup lib?
as far as i can see, the init starts in the jsinitializer for each field.
And then it is processed by "Plumsail.CSL.CrossSiteLookup.Init"
Can i use the "Template" "Custom" and some sort of JS to manipulate a default external lookup inside the spform?
The default html for a normal lookup looks like this (if i get it right):
Thx alot!

Some addon:
Inside SPForm-form, i have the ability, to read and set the normal external Lookup:
So "all" i need now, is to overwrite the default rendering of this field 
I want to init it s crosssitelookup and the the field value on submit or on change or what ever

Dear Ragesoft,
I am not quite sure you could use Cross-site Lookup field here, it would probably be easier to just create your own field similar to it in functionality.
I guess you could try to use something like custom template - https://spform.com/custom-fields/custom ... nline-mode
Or maybe even create an HTML field with HTML control, and use JS to save value to SharePoint field, though I do guarantee that this will work.
