Use this dialog box to update forms that were
created in Designer version 6 to version 7. Updating older forms
will result in the shifting of some text, which may require manual
adjustment. In addition, script handling of enter and exit events on
drop-down list boxes is affected. If the older form will be viewed
primarily with Acrobat 7.0.5 or Adobe Reader 7.0.5 or later, use
this Compatibility dialog box to update the form to version 7.
To display
this dialog box, select File > Form Properties and click Compatibility.
If your form was created in version 6, you will see buttons you
can use to update to version 7.
-
Revert Rendering Model
-
Forces all versions of Acrobat to use the previous form rendering
model that was available in earlier versions of Designer.
By
default, Acrobat now uses a new form rendering model (Direct Rendering)
for rendering PDF forms. The new form rendering model provides better
performance than the previous form rendering model. However, the
new form rendering model can cause differences in the appearance
and performance of legacy forms that use the previous rendering
model.
-
Revert Text Formatting or Update Text Formatting
-
If you open a form from an earlier version of Designer, the
text formatting rules are different.
To use the current text
formatting rules, click Update Text Formatting. Updating older forms
will result in the shifting of some text, which may require manual adjustment.
To
use the version 6 text formatting rules, click Revert Text Formatting.
-
Revert Event Model or Update Event Model
-
If you open a form from an earlier version of Designer, the
behavior of the enter events on the form is different. In version
7, the first time a user clicks in a drop-down list, an enter event
is sent with the reenter property set to false. If the user clicks
in the field again or presses the Enter key, another enter event
is sent with the reenter property set to true.
To use the
current event handling rules, click Update Event Model. If you want
the enter event to occur each time a user clicks a drop-down list,
update the event model.
To use the version 6 event handling
rules, click Revert Event Model. For example, if you have a form
that was created in Designer version 6, and you want to download
data from the server only once on the first enter, you may want
to keep the old event model or revert to the old event model.
