使用ironPython进行Spotfire另存为

Question

我正在尝试使用ironpython脚本在'onPropertyChange'事件中将SaveAs文档另存为库项。 附加到该属性的脚本代码：

# Import namespaces
from Spotfire.Dxp.Application import DocumentSaveSettings
from Spotfire.Dxp.Framework.Library import *

# Set the folder path and file name
folderName = "/Spotfire Test Folder/Reports"
fileName = "Test File"

# Set up the LibraryMangager and ensure that we can 
# access the folder path specified
libraryManager = Document.GetService(LibraryManager)
success, libraryFolder = libraryManager.TryGetItem(folderName, LibraryItemType.Folder)

# Embed the data
Document.Data.SaveSettings.EmbedAllSourceData = 1

# Save the document back to the Library
Application.SaveAs(libraryFolder, fileName, LibraryItemMetadataSettings(), DocumentSaveSettings())

不幸的是，我收到以下错误：

处于“执行”状态时，对命令历史记录的操作“ BeginAggregatedTransaction”无效

• 脚本有问题吗？ 如果没有，有没有办法使用脚本或api函数（通过javascript或ironpython）另存为库项？

Answer 1

显然，spotfire中的所有ironpython脚本都在事务中运行，并且某些api函数（例如“ SaveAs”）正在尝试调用第二个事务，这会导致脚本失败。

因此，“ SaveAs”函数调用应在应用程序线程上运行，从而脱离事务。

起作用的最终代码：

# Import namespaces
from Spotfire.Dxp.Framework.ApplicationModel import ApplicationThread
from Spotfire.Dxp.Application import DocumentSaveSettings
from Spotfire.Dxp.Framework.Library import *

# Declaring the function which will run async
def g(app, folder, fileName, metaData, saveSettings):
   def f():
      app.SaveAs(folder, fileName, metaData, saveSettings)
   return f

# Set the folder path and file name
folderName = "/Spotfire Test Folder/Reports"
fileName = "Test File"

# Set up the LibraryMangager and ensure that we can 
# access the folder path specified
libraryManager = Document.GetService(LibraryManager)
success, libraryFolder = libraryManager.TryGetItem(folderName, LibraryItemType.Folder)

# Executing the function on the application thread, and Save the document back to the Library
Application.GetService[ApplicationThread]().InvokeAsynchronously(g(Application, libraryFolder, fileName, LibraryItemMetadataSettings(), DocumentSaveSettings()))

根据Tibco的回答：

“希望在发布Spotfire 7.5时，我们将针对这些类型的问题提供更永久的解决方案，因为我们可以选择不从UI内在事务内运行代码。”
