When you create a data connection, Designer creates a data
description and saves it in the form. In addition, the Data View
palette displays a hierarchy view of the data source. If the data
source is an embedded XML schema or Adobe data model, the hierarchy
is generated from the description saved in the form. If the data
source is a non-embedded XML schema, an XML data file, or WSDL file,
the hierarchy is generated using the external file.
When you reopen the form, Designer determines if the source file
for the data connection has changed. If it has changed, you are
prompted to update the connection. When you update the connection,
Designer recreates the data description that is saved with the form
file. It also regenerates the hierarchy in the Data View palette.
To prevent the update warning, in the Data Binding panel of the
Options dialog box, clear the Show Update Dialog When Source File
Changes option.
Updating the Data View palette for non-embedded XML schema data connections
When
the source for a data connection is a non-embedded XML schema, an
XML data file, or WSDL file, the hierarchy view in the Data View
palette is generated using an external file. If the external file
changes, when you reopen the form, the hierarchy in the Data View
is regenerated to reflect the changes. If the external file changes
when you are editing the form, a dialog box is displayed. This dialog box
enables you to reload the hierarchy in the Data View palette .
To
prevent these warnings, when you open the form file, update the
data connection when you are prompted. Alternatively, in the Data
View palette, select the name of the data connection, right-click,
and then click Connection Properties to re-create the data connection.
