[SOLVED] Datasources in a datamodule aren't available for one form
lazarus / 16-Databases

I started a small project with 1 DM and 4 Forms (3 of them using the
DM). All was fine and suddenly only the login form doesn't "see" the
components into the DM anymore.

I tried to add new TDBEdits and in the DataSource property I always
see (none).
In the source code I'm able to type damMain. plus any component name
inside it and the auto complete fills it correctly. (and yes, I added
the DM in the Uses clausule of the form  )

So, is there any "special" file used by Lazarus that could be
corrupted or something else?
Any idea about what happened?

Thanks
Micheus

Is your Datasource in the DataModule ENABLED?

Pascaluvr, thank you for answer.

Yes, and I checked it again.
The problem is already present at design-time and only with this
specific form (that was working before).
You can see it on this 41s video I made for better show my issue.
I'm finding I'll need to rebuild this form.

Just now, it has occurred me try to remove the file from project and
add it back - It worked! 
- File->Remove from project;
- I commented any reference in the other files to this form;
- Rebuild the project CTRL+F9;
- After checked OK, File->Save All and Quit from Lazarus;
- Load Lazarus again;
- Load the problematic file and File->Add Editor File to Project...

... and I already was able to see the datamodules on that DM.

So, it seems there is some extra information, in some place, being
used by Lazarus.

I actually use the DataSet's in DataModule and the DataSource's in the
Form that need connect to DataSet.
