Hi Guys.
- I have a Wizard that generates a new form at runtime, containing a Grid Control.
- The Wizard passes a reference to one of its temp Tables to the form, in which I use linkPhysicalTableInstance in the runtime form's datasource init() method. - The GridControl has an add new record button, which inserts records in to the tmp table reference.
- The new record is saved to the reference temp table correctly, and displays in the grid *when the runtime form is closed and reopened* but does *not* display in the grid immediately after the insert.
- To add to the weirdness, after a runtime form has been created, a record inserted and then closed, subsequent run time forms do display new record insertions immediately, without needing to be re-opened. Some code snippets below.
Can anyone please suggest why this behavior only happens for the first time that data is inserted in to the temp table, but displays fine for subsequent runs of the runtime form?
Creating the runtime form:
args = new Args(formstr(RunTimeFormName));
formRun = classFactory.formRunClass(args);
formRun .parmRuntimeFormsGridTmpDS(sysWizard.ReferenceToWizardsTableTmp()); // Passing a reference for Wizards tmpTable to form
formRun .init();
formRun .run();
formRun .wait();
formRun .detach();
RunTime Form's parmDataSourceMethod:
public void parmRuntimeFormsGridTmpDS(CommentsGridTmp _ReferenceToWizardsTableTmp)
{
ReferenceToWizardsTableTmp = _ReferenceToWizardsTableTmp;
}
DataSource init() method:
public void init()
{
super();
RuntimeFormsGridTmpDS.linkPhysicalTableInstance(ReferenceToWizardsTableTmp);
}
RunTime Form's New button clicked method:
void clicked()
{
int64 numRows;
;
// Refresh records loaded in grid DS to ensure correct number of records for setting initial index number
// Note: SomeId is passed in Args() record, its passing fine as is the number of rows count - and replacing with a static value has no effect.
select count(RecId) from ReferenceToWizardsTableTmp
where ReferenceToWizardsTableTmp.SomeId == someId;
numRows = ReferenceToWizardsTableTmp.RecId;
ReferenceToWizardsTableTmp.Comment = "Comment " + int642str(numRows + 1);
ReferenceToWizardsTableTmp.Filename = "";
ReferenceToWizardsTableTmp.someId = someId;
ReferenceToWizardsTableTmp.insert();
element .Task(#TaskF5);
// super();
}
So as described above, the first time that the runtime form is created and a record is inserted, it doesn't display. Reopening the form will display the inserted data fine. Also, after reopening the form any new records inserted appear in the grid in real time.
So I guess it must be something to do with the linkToPhysicalTable and where the grid fields look for records to display.
Any help appreciated!
