Refreshing forms from the table.

[arnam]

Hi,

In the method modifiedField my code modifies fields from the table
(lines of the document) and a fields in another table (document
header). (Tables are associated with foreign key)

How to call a refresh on the form, from the code that is implemented
on the table? Few diffrent forms may use these tables, so I wan't to
refresh them all.

Sorry for bad english.

Regards
Peter

In general, you can call something like this:

if (table.isFormDataSource())
{
table.dataSource().refresh();
}

But you shouldn't save a record in the modifiedField(). Use this method only
for an initialization of fields. Simply set values to the "this" buffer (e.g.
this.Field1 = '') and no refresh is needed.
Also, you should update other tables during a record saving - e.g. in the
insert() method.

On the first table (lines of document), from which modifiedField() is
executed I use "this" buffer, but related table (header of document)
is modified using 'select forUpdate' clause. So first table has
relation to dataSource, but second table doesn't (dataSource() is
nil).

Yes, but I need to display updated data on the form, on the controls
connected with the header table, immediately after update of lines
table.
