Hello,

When doing a create datawindow (dw_1.Create ( ls_dw, ls_error )) the drowpdowndatawindows of 
the columns that are not retrieved because the object does not exist. 

With the reports (example with composites), putting the object as psr in the dataobject works 
for me, but with the drowdowndw I don't know how to do it.

Any idea?

Thank you in advance,

Juan

Hello Chris.

Thanks for your answer.

The problem is that I don't have the dddws in the target.

With the composite reports I leave them in the same folder of the executable as psr and 
it works fine but with the dddws it doesn't work for me.

Thanks,

Best Regards, Juan

Is there a way to add the objects dynamically because I have the definition of the dddw in the database?



Thanks,

If you have the dddw in the database, then before creating the primary DW, you might try saving the dddw syntax as a temporary text file, then calling LibraryImport() to add the dddw to a PBL that is in the application's search path. In theory that should work.

save to pbl won't work for powerserver, and possibly won't work in future version of PB as pbl elimination will be a new feature.



this is an enhancement request to allow child datawindows to be created from syntax at runtime. This WAS a feature in PS 2020 and prior versions, so it is possible to do, but appeon hasn't implemented it in powerbuilder.

want this? Then enter you own enhancement request, otherwise they will think only 1 developer would use this feature.

Hi Juan;

  That should happen automatically after the Create() command when you then issue a Retrieve() command on the newly created DWO. At that point, all DDDW's should have fired as well & their datum should be populated.
