Common Errors
Though some error messages are specific to a task in particular, others may apply to any and all tasks
because they are related more to the system than to PReS itself. Some examples would be W3813, W3830,
W3991, W4005. These correspond to issues such as not having any space to write files, permission errors
on folders or files, etc.
Comments Tab
The Comments tab is common to all tasks. It contains a single text area (Task comments)that lets you
write comments about the task. These comments are saved when the dialog is closed with the OKbutton,
and are displayed in the Task Comments Pane.
NewWild Card
For a given Metadata Field Management action, all nodes of a given level mightbe updated with a new
Field Value.To accommodate this,metadata/data selection functions have beenmodified to accept a wild
card parameter "?", indicating the function operates on allnodes (not just one) of a given level.For example,
in a PDF emulation, the format of a selected region is:
region(?,0.59375,2.21875,1.85416,2.51041,KeepCase,NoTrim)
where “?” represents the current physical data page processed by the task.
Limitations
l The name of the metadata field to add must adhere to these syntax rules: start with a letter, followed by
zero or more letters, numbers, underscore or dash. The name is not case-sensitive.
l
Metadata Fields Management actions on the page level are not possible since the entire task
execution is based on the data page node.
l
The task raises an error if the selected Metadata Fields Management action is Sum and if one of the
field valuesis not numeric.The task supports approximately 15 digits of precision in a range from 2.23
x 10
-308
to 1.79 x 10
308
.
