Is the page number field? Hmmm, I inspected one and it supports update(), not refresh(). So no, I don't think that I mean refresh().

Can you insert the field and then, since you still have a copy of the field, call update()?

This is supported by  com.sun.star.util.XUpdatable

Read this:

http://wiki.openoffice.org/wiki/Documentation/DevGuide/Text/Text_Fields

And I quote:::::::::::::::::::::::::::::::

All fields support the interfaces com.sun.star.text.XTextField <http://api.openoffice.org/docs/common/ref/com/sun/star/text/XTextField.html>, com.sun.star.util.XUpdatable <http://api.openoffice.org/docs/common/ref/com/sun/star/util/XUpdatable.html>, com.sun.star.text.XDependentTextField <http://api.openoffice.org/docs/common/ref/com/sun/star/text/XDependentTextField.html> and the service com.sun.star.text.TextContent <http://api.openoffice.org/docs/common/ref/com/sun/star/text/TextContent.html>.

The method |getPresentation()| of the interface com.sun.star.text.XTextField <http://api.openoffice.org/docs/common/ref/com/sun/star/text/XTextField.html> returns the textual representation of the result of the text field operation, such as a date, time, variable value, or the command, such as CHAPTER, TIME (fixed) depending on the boolean parameter.

The method |update()| of the interface com.sun.star.util.XUpdatable <http://api.openoffice.org/docs/common/ref/com/sun/star/util/XUpdatable.html> affects only the following field types:

 * Date and time fields are set to the current date and time.
 * The |ExtendedUser| fields that show parts of the user data set for
   OpenOffice.org, such as the Name, City, Phone No. and the Author
   fields that are set to the current values.
 * The |FileName| fields are updated with the current name of the file.
 * The |DocInfo.XXX| fields are updated with the current document info
   of the document.

All other fields ignore calls to |update()|.

I hope that this helps some!

Andrew,
   I think you are right, I add a sleep time after insert page number
field before getText, the page number can get correct.
But I think it's a bug for page number update issue.

Have you tried forcing an update? If so, then you won't need to wait.

I expect that an update may be a time consuming operation (say if you
insert at page number 400, and it must refresh from the start). I once saw
a problem where a document would open, but the initial page numbers were
wrong. It took a while for the page numbers to be updated after the
document loaded. The final solution was to issue a full refresh, which took
time, but made it happen. So, the trade off was to allow the user to
immediately see and edit the document rather than forcing them to wait for
the refresh to occur on load. With a large document, this can take time.

My guess is that it takes significantly more time to create and insert a
field than to trigger the update process. When the API is used to insert,
we have no context on the operation so it seems reasonable to not make an
immediate update before return. If the update process takes 1000 times
longer to occur (probably depends on document size and other factors,
depending on what is updated), then if I want to insert 100 fields, what
might have taken a fraction of a second may now take minutes.

Commands triggered from the GUI can make the reasonable assumption that
the user is not likely to perform that task a 100 times, and that a user is
sitting right there and probably desires an immediate response to the
command, so then the triggered code (a dispatch) includes the update task
as part of the process.

If you think that not updating the single field immediately is a bug, you
should try inserting a Table Of Contents (TOC).

So, although you are certain that it is a bug, and you may be right, I
might call it a design decision that tends to make the typical user
experience more performant; which is the usual case..... but this is mostly
speculation on my part.


Oliver, I have tired again, on my computer, if don't add sleep time, it
has problem for exist more than 2 page sample fie. You can try this sample,
add a page nubmer at end of this document. pls get this sample from
attachement.

     My expectation is that this is not a bug.

     I think that this is probably a timing problem based on the speed
     of the computer, the size of the document, how busy your CPU is,
     etc. If you do not have a number, then the values have probably
     not updated yet. Remember that the data model has no idea what
     page number it really is. This value must be updated by the view
     model / current controller (or something similar). If you have a
     value, then it just so happens that the values updated
     immediately. If you insert the value using the GUI, that code is
     smart enough to then trigger the update before it returns.

             OK, I had to  look...

             For a text field, see if you can call update. This may not
             work if the
             document has not finished repaginating. I have heard of
             cases where a
             document had not finished doing that before someone tried
             to do stuff to
             it. The solution was to tell the document to full refresh
             (probably using a
             dispatch).

                 look it up and I really need to run but figured it
                 might help you a bit and
                 you can look for the various refresh items (I think
                 that you can refresh
                 each index and for fields I think there may be a

                 refresh but I don't remember... have not done it in a
                 long time.).

                     Hi All,
                          Using UNO API I do below operation.
                     1.Launch a odt document,
                     2.Create a page number field and insert into this
                     docment
                     3.Get the document text

                     But in the step3, page number is not contained in
                     the get text. But if I
                     launch a doc document, I can get the page number
