The Report palette displays different warning and error messages relating to aspects of the form design. When a warning message is generated, these details appear in the Warnings tab in the Report palette:
LiveCycle Designer ES generates these types of warning messages:
Target warning messages appear when you try to use a feature that is not supported in the Acrobat and Adobe Reader target version. For information on addressing target warning messages, see Addressing target warning messages.
Marker warning messages appear when a problem occurs with an object. These messages are associated with warning symbols, such as a yellow triangle or white “X” within a red circle. For information on addressing marker warning messages, see Addressing warning marker messages.
Scripting error messages occur when there are issues with scripts in the form design. When you save or preview the form design using the Preview PDF tab, scripting error messages appear in the Warning tab in the Report palette. For information on scripting error messages, see Addressing scripting error messages.
