[Fmx, Livebinding] TListview uses FMX.Bind.Editors, Sources are missing

[Rollo62 503]

Hello there,

 

I was trying to integrate some features of the ModernListView from here into my projects.

It all looks very good, until I got to that point where a form uses Livebinding to populate the Listview.
This worked well before, and I would like to keep that, otherwise I need to rework much more than desired.
 

Since ModernLV makes changes to the FMX.ListView.pas it gives the following error message:

F2051 Unit Fmx.Bind.Editors was compiled with a different version of FMX.ListView.TCustomListView

Yes, pretty clear;:  But I've expected to find FMX.Bind.Editors.pas in my source folders, but I cannot find it 

So FMX.Bind.Editors seems to be secret module, hardcoded in the DCU binaries somewhere.

 

I used an extended TListView approach before, extended by two measures:

1.  Extending the TListView class by some variables I need, using an interposer class

2. A helper for adding the missing functionality

 

This approach worked well, and I have never have seen any issues or a message like above.
So this approach changed the binary DCU version, since I didn't touch FMX.ListView.pas directly.

 

With the ModernListView approach, there is a patched FMX.ListView.pas file needed, which of coarse changes the DCU version.

I could try to get back to the 2-step verson like above, but I don't know yet if all changed might be in (probably not).

 

Do you have any suggestions howto handle this, best of all if  FMX.Bind.Editors would be available somewhere ?
Since I have implemented my changes in a few projects already 80%, it would be really nasty to switch back.

 

Ok, its already quite late, maybe tomorrow I can see some light on this issue ...

Yes it was late yesterday:

 

I can find the source here

As an addition to this topic:

I just stumbled about a great article from Jitendra Kumar regarding the deeper explanations to this type of error

F2051 Unit Abc was compiled with a different version of Xyz
