Use this dialog box to specify a number of standard settings that LiveCycle Designer ES will use for each form design. If necessary, you can override these settings for an individual form design.
Specifies the default Acrobat and Adobe Reader target version in which the form will be run. LiveCycle Designer ES validates the form design as you work and displays a warning message on the Warnings tab in the Report palette if a feature that you add fails the validation for the selected Acrobat and Adobe Reader target version. You must also ensure that you have the version of Acrobat installed that matches the target version that you select; otherwise, you may get an error or a warning message when you click the Preview PDF tab. For example, if you select Acrobat and Adobe Reader 6.0.2 or later as the target version for the form, ensure that you have Acrobat 6.0.2 installed. The target version you select is also displayed at the bottom of the Save As dialog box when you save a form.
Specifies the default language and country, or region for the form design, which defines the format and punctuation of date, time, date/time, numeric, and currency values displayed in the form. Locale options are organized first by language and then by country or region. The form locale also defines the language used by the spell-check feature. For forms that have print output for multiple locales, select the Viewer’s system locale option.
Specifies that scripting changes in a form will be preserved automatically when the form is saved. If the form is certified, scripting changes will not be saved. If the form is uncertified, certification of the form will not be possible.
Specifies that scripting changes in a form will be preserved through scripting when the form is saved. You must use the delta script object to do this. The Manual option is useful for certified forms.
Applies strict scoping rules to JavaScript. Applying strict scoping rules enhances the performance of forms and makes the script more portable. Performance enhancements apply to forms targeted for Acrobat 8.1 and later.
You should not apply strict scoping rules in forms that are targeted for versions of Acrobat earlier than 8.1. When you select strict scoping and then choose a target version earlier than Acrobat 8.1, the scripts may behave differently or not work.
