The LiveCycle Designer ES workspace provides a number of ways to assist you with debugging your calculations and scripts.
Displays target and warning marker messages as well as all JavaScript or FormCalc scripting syntax errors when you select the Check Script Syntax command from the Tools menu or click the Check Script Syntax button in the Tools toolbar. For more information, see “To check script syntax”.
When you double-click a syntax warning message in the Warnings tab, the script that contains the error is loaded into the Script Editor, and the line with the error is highlighted.
You can also double-click a warning message to select the related object in the Design View and the Hierarchy palette, and press F1 to display information about how to fix the warnings.
If you include fields on your form design that are bound to a data source, the Binding tab can assist you by displaying lists of fields based on how you defined their data binding. For example, you can list only fields with Global Data Binding or only those with no data binding defined. This feature is especially useful on forms that have a large number of data bound fields.
Displays validation messages, JavaScript or FormCalc scripting execution errors, and design-time form rendering errors generated by LiveCycle Designer ES when you import or save a form, or preview a form using the Preview PDF tab.
You can use the Hierarchy palette to determine the location of a form object for a reference syntax. The Hierarchy palette is a graphical representation of the structure of a form. It displays the contents of the Master Pages and Design View tabs.
The Hierarchy palette also displays referenced objects under the Referenced Objects node. A referenced object is an object that is added to a form only when it is required. Wh
enever data flows across multiple pages or content areas, the overflow leader and trailer subforms are inserted into the form in the appropriate places.
Every LiveCycle Designer ES object that can be bound to a data source includes a Binding tab in the Object palette. If you bind an object on your form design to a particular data node from your data connection, the Default Binding (Open, Save, Submit) list displays a valid FormCalc reference syntax for accessing that data node. You can use the FormCalc reference syntax in other calculations or scripts for testing purposes.
The XML Source tab contains the form design’s XML code. The XML source code defines all aspects of the form. You can use the XML Source tab to view the XML Form Object Model structure of a form design and to understand the relationships between objects and properties. In the XML source, the XML element names are equivalent to the object names in the XML Form Object Model, and attributes are equivalent to properties.
When you select an object in the Hierarchy palette and then click the XML Source tab, the first line of the corresponding element is highlighted. The object name in LiveCycle Designer ES, as listed in the Hierarchy palette, becomes the value of the name attribute in the XML source.
You can set options in the Tools > Options dialog box for viewing the source in the XML Source tab, such as showing or hiding line numbers and setting the syntax coloring.
You may also find it useful to change the default options for the Script Editor to make it easier to debug your calculations and scripts. These options are in the Workspace panel of the Options dialog box, which is available by selecting Tools > Options and then selecting Workspace from the list on the left. For example, you can choose to display line numbers in the Script Editor or change the formatting of FormCalc or JavaScript syntax.
