Challenge with Batch Task API and ISegmentPair.Properties.TranslationOrigin

Question

Dear community, 
 we would like to create a custom word count batch task. Now we have the challenge that when the custom batch task runs before the SDLXLIFFs have been opened the first time, we get an error &ldquo;object not set to an instance&rdquo;, because &ldquo;segmentPair.Properties.TranslationOrigin&rdquo; is null while we are trying to access its property &ldquo;OriginType&rdquo;. However, after the the SDLXLIFFs have been opened once, the custom report is created successfully. 
 
 public override void TaskComplete() 
 { 
 foreach (ISegmentPair segmentPair in segmentPairExtractor.segmentPairs) 
 { 
 if (segmentPair.Properties.TranslationOrigin.OriginType == null) 
 
 Romulus Crisan (former member) , can you maybe help? 
 
 Best wishes, 
 Simon

Hi Simon, If TranslationOrigin is null, it means the segment is empty and the file has never been opened and saved. Why not just check for null and skip those segment pairs? if (segmentPair.Properties.TranslationOrigin != null) { // TranslationOrigin is not null, so check OriginType } Or with C# 6 Syntax if (segmentPair.Properties?.TranslationOrigin.OriginType == null)

Hi Simon, 
 Thank you Jesse for following up; no.1 
 I have been able to reproduce the issue as you have described it above; please review the latest version of the example project here: 3731.CustomWordCounter_v2.zip 
 I conferred with Iain Shaw on this matter this morning + as Daniel Brockmann has outlined, the repetitions table that you are making reference to is in fact created from the studio editor, as a convenience at that level. It is possible to read that information through the translation origin model while iterating over the segments from a content processor, however, that information would first need to be generated by the editor; not possible to generate that table directly from the project API. 
 It is however possible to create your own table and manage it as you are iterating over the segments, by generating a hash-code of the source segment and comparing against that to identify repetitions. 
 A more elegant solution might be to recover the analysis statistical information from the ProjectFile itself that is accessible through the batch task API.

However, you would need to ensure that an &lsquo;Analyze Files&rsquo; batch task is executed at least once prior to running your custom batch task; considering that the AnalysisStatistics data is recovered from the project only after an analysis operation has taken place on that file. To accomplish this, you could add a custom task sequence, as follows: 
 
 Select Batch Tasks>Custom>Task Sequences 
 From the Task sequences dialog, select &lsquo;Add&rsquo; 
 Provide an appropriate name + description and then add the &lsquo;Analyze Files&rsquo; task + your custom batch task 
 Click &lsquo;OK&rsquo; and save the task sequence details 
 
 Note : batch tasks are designed to chain tasks together, so it would not make sense to call 'Analyze Files' directly from your custom batch task; instead chain the tasks in a sequence of events, so to speak. 
 Refer to the screen shot underneath

The new Task Sequence would then be available from the batch tasks menu, as follows:

Would this type of solution suit your requirements?
