Can I export a subset of data driven pages in a scheduled process using a def query?

I am attempting to export a set of map books using a common index layer which has an attribute telling me which map books each feature in the index belongs to.  Interactively I can open ArcMap, change the definition query on the featureclass and refresh the data driven pages before exporting each map book.  I am attempting to do this in python so I can schedule it to update the books at a regular interval.  I could do this with a search cursor to loop through checking the attributes and append each page, although it appears the code below should work conceptually at doing what I'm attempting.  It runs (with the exception of the mxd.dataDrivenPages.refresh() line), but exports all of the features in the original unmodified definition query.  Any thoughts on if this can't work, why, or is the loop with a cursor my only option?

import arcpy mxd = arcpy.mapping.MapDocument("c:/temp/MapTemplate32KOneLine.mxd")  for myLayer in arcpy.mapping.ListLayers(mxd,'OneLineBoundaryTileEdit - 32K Index'):  myLayer.definitionQuery = "SUBTYPECD = 3 AND DEPOT LIKE '%BAR%'"  mxd.dataDrivenPages.refresh() mxd.dataDrivenPages.exportToPDF("C:/temp/BAR.pdf","ALL","","PDF_SINGLE_FILE","100","FASTEST")


Note:
The error I get from the mxd.dataDrivenPages.refresh() line is below.
Traceback (most recent call last):   File "testExportDataDrivenPages.py", line 13, in <module>     mxd.dataDrivenPages.refresh()   File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\_mapping.py", line 266, in refresh     return convertArcObjectToPythonObject(self._arc_object.refresh(*gp_fixargs((args), True))) ValueError: PageLayoutObject: Error in refreshing RefreshDataDrivenPages

Apparently you have to stop editing, then everything is fine...

I can leave the code up if it's useful for reference or delete the post.

Another option to consider is to simply run a query on your index layer (e.g, SelectLayerByAttribute) and export using the selected index features.


ddp.exportToPDF(outpdf, page_range_type="SELECTED")

I am having the same error in one of my scripts and this is the only post I can find where DataDrivenPages.refresh() gives the value error.  Are there know issues beside editing that would cause this to be thrown from python but not from the gui itself as the OP had?

error on line: line 139
error in file name: C:\data\ArcGISServer\Reporting\OccProdReport.py
with error message: ValueError: PageLayoutObject: Error in refreshing RefreshDataDrivenPages

Are you doing anything else to the index layer dynamically while the script is running?  I once tried building the index layer on the fly (based on the area of interest) while it was being referenced within the same MXD the script/DDP was working against.  The solution was to work build the index using one MXD and the map pages using another MXD (but all with a single script).

Please provide more detail.

I am doing exactly as you say.  I update the index layer dynamically while the script is running and then try to refresh data driven pages at which point I get the error I posted above (This works at 10, not 10.1).  After the code fails I can open my mxd, see that it is now pointing at the updated index layer and run the refresh manually on toolbar and it works with no errors.  It is not happy when you try to do this with python though.

My code is below.

I got around it by explicitly updating the datasource before calling refresh as below.

      
 ##Replace data source
        buf.replaceDataSource(arcpy.env.scratchGDB, "FILEGDB_WORKSPACE", "buffer")
