使用 ironPython 的 Spotfire 另存为

Question

我正在尝试使用 ironpython 脚本将文档另存为 'onPropertyChange' 事件中的库项目。附加到属性的脚本代码：

# 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：

在状态 'Executing'

中对命令历史的无效操作 'BeginAggregatedTransaction'

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）保存为库项目？

Answer 1

显然，交易中 spotfire 运行中的所有 ironpython 脚本和一些 api 函数，例如 'SaveAs' 都试图调用第二个交易，这导致脚本失败。

因此，'SaveAs' 函数调用应该在应用程序线程上运行，从而脱离事务。

有效的最终代码：

# 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：

"Hopefully when Spotfire 7.5 is released we will have a more permanent solution to these types of issues since we can then select not to run the code inside a transaction from the UI."
