Description Robert Großkopf 2012-05-01 00:34:03 UTC
When creating a form and a subform you have to define the relations between form and subform. There is a possibility to link from one form to another. When you youse the litte wizard for it and press the button, that it should suggest the right values, it only works with the fist field of the subform with the right fieldtype. Relationships, which are created in the database, are not consulted.

When creating whole forms with the wizard it works right. Wizard reads the relationships right from the database.

Database with 3 tables, one table with two foreign-keys.

Try to change the relation between form and subform in the form "Leser_subformtest" with the suggestion of the dialog. It suggests wrong values. The form itsel is created with the form-wizard. This wizard suggests the rigtht values.

Detailed description how to choose the dialog with wring suggestion

In this description is declared how to find the wrong dialog. The suggestion of this dialog works in the right way, when I copied two tables, switched the position of the foreign-keys in one of the tables and declared the relationship new.
Without declaring the relationship the dialog didn't suggest anything - the button is disabled. But the function behind the button doesn't read the relationship at all.

@ Robert,

thx for attach 66240. But I can´t reproduce some steps. Please list more details in your document.

You wrote:
When you start the form-wizard with the table „Leser“ you could choose the table „Ausleihe“ as subform. The relation between both tables is choosen automatically.
Asks from me:
1) What means "start the form-wizard with the table „Leser“". Please describe exactly the procedure. E.g. do you choose table "Table: Leser"? And which "available fields" have you chosen?
2) I created a form with the "Wizard to Create Form". I have chosen as subform "Table: Ausleihe". Also here: Please describe exactly the procedure. E.g. have you chosen the automatic selection or the "manual selection"? And which "available fields" have you chosen?
3) The next steps?

Asks from me:
1) Please describe exactly the procedure ("you could chosse the entries for Link fields in a dialog")
2) What do you mean with "See the cursor over the three point"?

1)  This dialog has a button „Suggest“. What dialog? How do open this dialog?
2) I will test the rest if I know the procedure.

Description how to get the right connection with form-wizard and the wrong with suggestion in the dialog

The way to get the right connection between two forms:
Use the form-wizard, add the subform, base on an existing relation. This relation is the relation choosen in Tools → Relationships.

After creating such a form (with subform) open the form for editing. Open the form-navigator and there, with a click of the right button of the mouse, open the properties of the subform. You could see the linked fields (as linked by the form-wizards). There are buttons between the fields, for example 
Link master fields... "ID" [...].
A click on one of this buttons opens a dialog. Choose in this dialog "Suggest". The wrong connection is suggested.

@ Robert
Now I understand what you mean. I can reconstruct your observation. But I want to discuss your conclusion.

You believe there is a bug.

IMHO it is possible that there is a normal behavior. Click on "Sugggest" shows all (!) fields of the table "Ausleihe" and this is IMHO correct.
I understand you so that your argues "The table "Medien" doesn't exist in this form" is the cause of the malfunction. I can´t comprehend this argument. "Medien_ID" isn´t a field of the table "Medien" but of the table "Ausleihe.

We need another base-specialist to confirm your suspicion.
Perhaps someone reading this bugreport can help.

I set Lionl to CC.
Comment 7 Robert Großkopf 2012-09-01 08:09:52 UTC
@Jochen:
Difference between the suggestion of the form-wizard and the dialog, where you can link the forms, is:
The form-wizard works right with the defined relationships of the database.

The dialog works wrong (or didn't have a look) at the relationsships. When I press "Suggest" I expect, that the dialog would have a look at the defined relationship - but I don't know, whre the dialog gets it's information from, not only from the relationship, also from the position of a field in the table and other tables in the database ...
Comment 8 Jochen 2012-09-01 08:45:49 UTC
Hi Rainer,
please have a look at comment 6 and comment 7.
Which procedure do you suggest?
Comment 9 Robert Großkopf 2013-04-21 19:29:59 UTC
The content of this report seems to be clear:
Formwizard reads the relationship of the table from the database.
If you will create a form without the wizard and will link a subform to a mainform, you could chose the fields, which should be linked. You could also press the button "Suggest" - but this "Suggestion" doesn't have a look at the relationship of the table like the formwizard. It suggests only the first field, which has the same fieldtype as the chosen fieldtype of the mainform.
I will change the status to "New".
Base works well without fixing this bug. So I change the importance also to "low" and "minor".
