5 Triggers
In order to streamline the tools available and simplify the development process for building Forms applications for the Web, triggers that are not applicable to Web deployment have been removed. In addition, the functionality of some triggers is being more strictly enforced.
The following sections are included:
Obsolete Triggers
The list of obsolete triggers.
Table 5-1 Obsolete Triggers
| Obsolete Triggers | Upgrade Notes |
|---|---|
|
ON-DISPATCH-EVENT |
Applies only to OLE and OCX items. Therefore, no upgrade path or replacement functionality. |
|
All V2-style triggers |
When you open FMBs that contain V2-style triggers, the triggers are dropped and a warning message lists the names of the dropped triggers. You should recode V2-style triggers into PL/SQL in Forms 6i, before upgrading to this release. |
|
When-Mouse-Move/When-Mouse-Enter/When-Mouse-Leave Triggers |
These triggers are ignored when running on the Web due to the amount of network traffic that would be generated. |
Stricter Enforcement of Triggers
The use of specific triggers is more strictly enforced. These triggers do not execute if they are used incorrectly.
