Set generate flag to false for index, but index will still be created

Question

I found that the generate flag for index will now be stored correct, even I close and reopen th ephysical model.
However, even i set the generate flag for an index to false, the DDL for the index will be generated. Any workaround?
Additional hint:
* The flag is considered if no physical model is opened.
* To not open the physical model is no workaround because if the physical model is not opened, no sequences will be generated.
Thanks in advance,

Hi David,
thanks for your answer. However, I do not see that this is a practicable workaround for me.
Let me explain.
* I have table A with a foreign key on column X to table B.
* I have set that data modeler should create missing indexes for foreign keys (preference/data modeler: automatic index generation for foreign key constraints enabled)
* If I generate DDL, I will get the missing index generated by data modeler (index name ends with FKX). That's fine.
* But, now I have a combined index of column X and column Y on table a. this index would make the automatically generated index needless - because it is already covered by the combined index.
* To avoid generating the needless index, I design an index on column X and set the flag for generation to false.
* If I have designed the index on column X, data modeler does not generate the missing index. However, the needless index will be generated even the flag is set to false.
Of course I can exclude the index from the generation in the generations dialog, but from my point of view I already decided not to generate the index in the relational model. In case the physical model has not been opened, the indexes having generate equals to false are excluded from the generation (could also be seen in generation dialog).
Cheers,
