1.  After I ran the Rendering Using VVT Symbology tool, some of my features were displayed as bright purple or pink.

Features will be displayed as purple if the attribute fields required for rendering have not been populated.  Bright pink features indicate that the attribute fields required for rendering are populated with erroneous values.

2.  Unintentionally, I deleted a record from the error table.

A back-up error table is created within each ReViewer session.  It contains a record of each error logged and can be used to restore deleted records.  The table shows a delete status for any records that were deleted from the error table.

  1. Open the back-up table by right-clicking anywhere on the error table records and selecting Open Back-up Table from the list.  The back-up table will appear in your ArcMap project.  Scroll to the right on the back-up error table so that you can determine which error to copy.
  2. Right-click on the appropriate error record in the back-up table.  Select Copy from the options.  This will copy the record directly into the error table, so you do not need to paste it into the error table.  If you have not already done so, delete the error record from the error table that has the incorrect information.

3.  The error description that I entered for an error needs to be changed.

It is not possible to edit the fields in the error table.  You need to delete the incorrect entry and create a new record for the error.

4.  When I click on the Select and Identify Tool, I do not see the attribute fields for the feature that I’ve selected.

Pick the layer from the dropdown list at the top of the Identify Results window and re-select the feature.  If there are no values in the fields, the feature has not been attributed.  Use GeoPop to attribute features.

5.  The Duplicate Error Tool is not working.

The Duplicate Error Tool can only be used with Point Notepad Tool.

6.  The information that I entered for an error record is incorrect.

You can copy the incorrect error record from the back-up error table to your working error table.  Only the original error information will show.

  1. Identify the error number (ErrNum) of the record in which you made the incorrect entry.  Let’s say the ErrNum of the record of interest is 8.
  2. Open the back-up table by right-clicking anywhere on the error table records and selecting Open Back-up Table from the list.  The back-up table will appear in your ArcMap project.
  3. Locate the record with ErrNum 8 in the back-up table.  Scroll to the right to make sure that you are looking at the record that contains erroneous information.
  4. Right-click on the record and select Copy from the options.  This will place a copy of the record into the error table.  You will see a new record created in the back-up table with a new ErrNum and a status that reads “Copied from Record #8.”  The new record that appears in the back-up and error tables will show only the information entered when the error was first committed to the table.
  5. Close the back-up table.
  6. Enter the correct error correction/correction validation information and delete the old, incorrect record.

7.  I ran Batch Validate on a feature class or selected set of features without any problem.  I want to run Batch Validate again, this time on new features or some additional features.  When I launch the batch validation, the features I want to have checked are not selected.  Batch Validate is not detecting the features.

You must clear the selection before performing a new batch validation.  The selection set that has been created will be checked until you create a new selection set.  Clear all selected features by choosing Clear All Selected Features from ArcMap’s Select dropdown menu.  Make sure your selectable layers are set according to your needs.  Launch Batch Validate and choose the checks you want to run.

8.  I tried to visit an error and got the following error message:

Error message - The associated layer referenced by the error table is no longer on the map

The error table does not store spatial data for an error record.  The record points to a feature class.  If you remove a feature class from the Table of Contents to which an error record points, you will receive the error message above.

  1. Re-load the feature class to which the error record points.
  2. If the Location field in the error table is not visible, make it visible using the Toggle Column Visibility Tool.
  3. Check the path name showing in the Location field for the record to determine how to add the feature class.
    1. If the feature class is a notepad feature class created using the Polygon, Polyline, or Point Notepad tools, use the Load Notepad Feature Class tool to load the notepad feature class(es) from the ReViewer session that holds the feature classes.  Look at the Location field in the error table to see the path name—it will include the name of the ReViewer session in which it is stored.
    2. If the feature class is one of the DFIRM data layers, use the DFIRM Layer Data Loader to add the appropriate feature class back into the ArcMap project.

9.  I ran batch validate and got the following message box:

Batch Validate window

There are no batch validation checks for the Annotation layers.  Change your Selectable Layers settings so that these layers are not selectable.  Clear the existing selection and re-launch Batch Validate.
