ProBindingSource and DataSets containing recursive data

Posted by karsten.ehrlich on 07-Mar-2011 10:22

Hi,
i have some issues with ProBindingSource in combination with ProDataSets containing one recursive data-relation and some other data-relations.
Basically, if you pass such a DataSet to the constructor of the ProBindingSource you will get a System.IndexOutOfRangeException.
The sample procedure attached to this post does the trick for you. (Since there seems no self-referencing data in the sportsdb I had to fake the recursive relationships. )
The dataset in the example looks like that.
define dataset dsEmployee for ttEmployee,ttFamily,ttSomething
 
  data-relation r1 for ttEmployee,ttFamily
    relation-fields (EmpNum,EmpNum) nested    
  data-relation r2 for ttFamily,ttEmployee
    relation-fields (SelfEmpNum,EmpNum) recursive    
  data-relation r3 for ttFamily,ttSomething
    relation-fields (EmpNum,EmpNum) nested
  . 
(We pretend father and son (or mother and daughter, or….) work in the same company.)
Now to the parts that make me wonder:
1. If you remove the third table and data-relation r3, everything works fine.
or
2. If you deactivate r3 (setting it to not-active), everything works fine.
or
3. If you leave r3 active and delete the self-referencing data, everything works fine.
or
4. If you set no DataSources at all and fill the entire DataSet using a "before-fill" call-back, everything works fine.
It doesn’t even matter if the third table contains any data or not.
Can someone shed some light into this, any ideas?
Thanks.

You should submit a bug for this issue.

Hi Karsten,

Support for recursive relations in ProbindingSource feature is provided from 11.0 release. This is already implemented in 11.0. I had tested this with the attached file and it works properly. However, In 102B service packs this feature is not available.

Thanks and Regards,

Anil Kumar.

I was able to reproduce this issue in version 11, both in and outside the debugger, so it is a bug.

The core (language) support for recursive data-relations was added to the product in version 10.2A,

so this bug can be fixed both in 10.2B and 11.0.

Is there any fix still foreseen for 10.2B?

Thx

I have no idea. I was just leaning on your previous post:

I believe your bug was OE00205963. It has been fixed in 10.2B05 and 11.0.

Thank you, Maura.

So we will patiently wait for SP5,... or OE11.
