Description finngruwierlarsen 2007-10-01 21:37:57 UTC 
Apparently is not possible to use the SpellChecker service from Python. The
following Python code makes OOo crash:

import uno
currentContext = XSCRIPTCONTEXT.getComponentContext()
smgr = currentContext.ServiceManager
spellchecker = \
smgr.createInstanceWithContext("com.sun.star.linguistic2.SpellChecker", \
currentContext)
locale = uno.getClass("com.sun.star.lang.Locale")
locale.Language = "da"
locale.Country = "DK"
spellcheckResult =  spellchecker.isValid("word", locale, ())
Comment 1 joergbudi 2007-10-02 20:00:36 UTC 
Hi,

is a bug (or more exactly two bugs) in the pyuno bridge.

Technical details: ( pyuno_except.cxx, 
1. instances of PyClass_Type have no __class__ attribute and  
2. the function isInstanceOfStructOrException cant cope with objects, that don't
have a class attribute.

Bye,

Joerg

Comment 2 joergbudi 2007-10-02 20:04:54 UTC 
The crash will be fixed some time in future, thus the ticket remains with me.

Neverthelesse, the script is errornous, replace

locale = uno.getClass("com.sun.star.lang.Locale")

with

locale = uno.getClass("com.sun.star.lang.Locale")()

(uno.getClass() returns the class com.sun.star.lang.Locale, to create a concrete
instance it, you have to invoke it.

Bye,

Joerg

Hi Joerg,

Thanks for looking into this problem. I must admit I don't understand much of
the technical details, but my script runs now, and that's good enough for me :-)
