Content Navigator known limitations: Some viewers have client and server side support limitations

Technote (troubleshooting)


Problem(Abstract)

The limitations include issues with specific viewers and server side viewing support.

Symptom


    Important: IBM Content Navigator includes viewers that are designed to support as many file types as possible. However, these viewers are not able to render every type of file with the same accuracy as native applications, such as Microsoft Word. The flexibility of the viewers can lead to differences in the way that the documents are displayed between the native application and the viewers. The severity of the differences varies depending on the complexity of the file type. In particular, PDF files and Microsoft Office files are difficult to render with complete accuracy in a universal viewer.

    If you configure IBM Content Navigator to view documents in one of the following viewers, you might notice some differences between the native application and the viewer display:
    • Ajax viewer
    • Applet viewer
    • Daeja ViewONE Professional viewer (formerly named FileNet viewer)
    • HTML conversion viewer
    • PDF conversion viewer

    Viewer limitations on client machines


    Applet viewer


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    Microsoft Office documents and Lotus documents can be viewed only on Microsoft Windows 32-bit or 64-bit client machines. If you try to view these documents on another type of client machine, you see the following message: "The document cannot be viewed. The document format application/msword is not supported by any of the available engines."

    Resolution:
    To view these documents, you can do the following:
    • Preview the document, rather than view the document
    • Configure one of the other viewers provided with IBM Content Navigator open Microsoft Office documents and Lotus documents
    • Configure another viewer plug-in that includes support for the Mac operating system with Microsoft Office MIME types




    Text documents might not render correctly in the applet viewer. For example, the tab stops and margins in the document might not display in the way that you expect and can cause unexpected text alignment and wrapping. This issue is caused by limitations in the third-party software that is used to render text documents in the applet viewer.




    If you have annotations in rich text format documents, the annotations might appear to be in different locations depending on the version of IBM Content Navigator that you are running. This behavior is caused by a change in the third-party software that is used to render rich text format documents in the applet viewer. Changes in the layout of the document, such as where text wraps, can cause the annotations to appear to be shifted or out of alignment with the associated text.




    Rendering and formatting is not supported when viewing HTML documents that contain CSS elements in the applet viewer.

    Resolution:
    HTML documents with CSS should be mapped to the HTML viewer map.





    Daeja ViewONE Professional viewer
    The Daeja ViewONE Professional viewer has replaced the IBM FileNet viewer.


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    The PDF and Universal viewer modules are Microsoft Windows 32-bit only. However, the standard viewing module supports both 32-bit and 64-bit versions of the JRE.




    The Universal viewer module is used to display non-image content, such as Microsoft Office documents, Lotus Symphony documents, and PDF documents. However, the Universal viewer module is not supported on Mac OS client machines.

    Resolution:
    You can use one of the following methods to view these types of documents:
    • Open the documents in the native applications.
    • Include another viewer in your viewer map as a fallback viewer for the Daeja ViewONE Professional viewer for Microsoft Office documents and Lotus Symphony documents. For more information, see Supported viewers, which describes the viewer fallback behavior.
    • Configure another viewer plug-in that includes support for Mac OS with Microsoft Office and Lotus Symphony MIME types.

    * If you are running IBM Content Navigator 2.0.3 or higher, you can contact your IBM Sales representative to purchase either of the following modules to use the Daeja ViewONE viewers to view Microsoft Office Documents:
    • IBM Daeja ViewONE Professional Module for Microsoft Office


    ✓*

    ✓*

    Partial redaction of vector-based images in PDF files is not supported with IBM Content Navigator.

    Resolution:
    When redacting a PDF, create redaction annotations of vector-based images to redact the entire image, not just a portion of an image.





    IBM Daeja ViewONE Virtual viewer
    The IBM Daeja ViewONE Virtual viewer was added in IBM Content Navigator 2.0.3


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    The IBM Daeja ViewONE Virtual viewer requires the IBM Daeja ViewONE Virtual Module for Microsoft Office license to support Microsoft Office documents.

    You can contact your IBM Sales representative to purchase the IBM Daeja ViewONE Virtual Module for Microsoft Office.




    The IBM Daeja Virtual viewer version 4.1.4 does not support the Text/Plain MIME type option.




    Line data applet viewer


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    The line data applet viewer is not supported on Mac OS client machines.




    The line data applet viewer is supported for 32-bit versions of Microsoft Windows only.





    Download as PDF


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    When you download AFP files as PDF documents, any colors in the AFP file are lost. Reading and writing of AFP files is limited to a pixel depth of 1 bit per pixel (black and white).




    When you download multi-part documents by using the download all parts as PDF functionality, only the first document is downloaded if you are using an external engine, such as Office documents.






    Viewer limitations on the IBM Content Navigator web application server



    Thumbnail view
    The thumbnail view displays an image of the first page of an image file or PDF file on the Document Information pane. On the following operating systems, the thumbnail view displays the first page of non-image documents, such as Microsoft Office documents, Lotus Symphony documents, and text documents correctly:

    • AIX 6.1
    • Windows

    However, the behavior for non-image documents, such as Microsoft Office documents, Lotus Symphony documents, and text documents is different on some operating systems.


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    On Linux for System z platforms, the thumbnail view displays a MIME type icon for non-image documents.





    Preview view
    IBM Content Navigator uses the HTML conversion viewer to generate document previews. The preview view allows you to preview documents without having the JRE installed on the client machine.


    Issue

    V2.0.2

    V2.0.3

    V3.0.0

    On AIX 7.1, the preview view cannot display presentation file formats, such as ODP and PPT files if you do not have a compatible Motif library installed.
