I think that i have a dwshare issue. We are sharing 6 child datawindows with the parent and the users are getting an error on one column in only one of the child datawindows that is being shared with the parent. The code for this is

ls_pmdc = GetItemString( 1, 'pmdc')

i think the issue is that with this one datawindow the column 'pmdc' is spelled as 'pdmc'.

When I test the most recent build, i am not getting any kind of an error message, but the users are getting an error message like 'uo_dw_workrequest.of_setDefault() invalid column at line 31'.

Could the misspelling in that one column cause this issue? When you do a share do all columns in all datawindows have to be spelled the same as in the parent?

 

Thanks

Jim

Hi Jim;

  For a DWO "ShareData" to work 100% ...

  1. Same number of columns
  2. Must have the the columns in the same order in the SQL statement

Hi Jim,

No, ShareData doesn't change the datawindow properties (e.g. column names). It only shares the datawindow buffer - means the data.

If you call a method for a child dw you have to use the column name of this child.

If you want to be more flexible you can use GetItemxxx using the column number.

HTH,

René
