Anyone have any idea on how to get SpawnWaitDialog to work? I have tried
various ways without success. (Calling the custom action as check and
asyncWait) Setting various options on the dialog SystemModal, Modeless,
KeepModeless as well.
Calling DoAction before SpawnWaitDialog as well as after.
>From what I can tell if I run the custom action synchronously
Calling the CA first then calling SpawnWaitDialog the custom action
does not run until after I manually close the dialog.
If I run the custom action first then the dialog never displays.
If I run the custom action asynchronously
Calling the CA first then calling SpawnWaitDialog the custom action
does not run until after I manually close the dialog.
If I run the custom action first then the dialog I have to manually
close the dialog.
I am running out of ideas.

Thanks for the reply Bob, but I have tried using the SpawnWaitDialog control
without success. What am I missing?
I have attempted the following:
I set the initial value of a property that my DTF custom action sets
(it sets the property to either 1 or 0).
Call the SpawnWaitDialog (The dialog just has a Text control to display
Validating - Please wait...)
Then call the custom action
Display a failed dialog if not successful
Otherwise go on to the next screen
Code:
Inside my Next Button control I do the following:
<Publish Property="DATA_VALID" Value="2">1</Publish>
<Publish Event="SpawnWaitDialog"
Value="ValidatingDialog"><![CDATA[DATA_VALID <> 2]]></Publish>
<Publish Event="DoAction" Value="ValidateDataImmediate">1</Publish>
<Publish Event="SpawnDialog"
Value="ValidationFailed"><![CDATA[DATA_VALID = 0]]></Publish>
<Publish Event="NewDialog" Value="[DataDlg_Next]"><![CDATA[DATA_VALID =
1]]></Publish>
Results:
The Validating dialog is displayed forever.
- I added a button on the validation dialog to publish "EndDialog" and when I
press it, the dialog goes away and starts running the custom action. So the
action is not getting run while the dialog is up.
- If I add the Modeless="yes" and KeepModeless="yes" properties on the
validating dialog it pops up and goes away immediately. Other combinations of
attributes do not see to make a difference.
- I attempted to move the DoAction to invoke the custom action inside of the
validating dialog. But adding a publish event under a Text control does not
seem to get invoked when the dialog is displayed.
Thanks for your help
- Tom

Use a SpawnWaitDialog control event before your CA.
