Confirmed on Debian Linux 5.03 and Windows XP, sos supect it crosses all OS
platforms - URL is to a - so far inconclusive - OO Community Forum topic I
started on the issue that also lists the same code examples included below.
As illstrated in the OO Basic macro at the very bottom of this desciption,
assigning a value to a Python-implemeted readwrite attribute of a (UNOIDL)
user-defined Interface causes OO to freeze - soffice process must be killed
before any activity can be resumed.
This can be reproduced using the following example UNOIDL and python modules:
Contents of XTestOOPythonComp.idl (compiled .rdb file to be added as OO
Extension UNO RDB Type Library):
#ifndef __names_nick_openoffice_TestOOPythonComp_idl__
#define __names_nick_openoffice_TestOOPythonComp_idl__
module names { module nick { module openoffice { module TestOOPythonComp {
interface XTestOOPythonComp
{
[attribute] double TestOOPyDouble;
[attribute] long TestOOPyLong;
[attribute] string TestOOPyString;
double OOCompFunction( [in] double a, [in] double b );
// The following should not be necessary to properly implement the Interface
with the above attributes
/////////////
double getTestOOPyDouble( );
void setTestOOPyDouble( [in] double newTestOOPyDouble );
long getTestOOPyLong( );
void setTestOOPyLong( [in] long newTestOOPyLong );
string getTestOOPyString( );
void setTestOOPyString( [in] string newTestOOPyString );
/////////////
};
service STestOOPythonComp: XTestOOPythonComp;
}; }; }; };
#endif

OO Basic Macro to test the issue (CAUTION: As written, it WILL freeze soffice)
Option Explicit
Sub TestOOPythonComp
Dim x as Object
Dim y as Double
x = createUnoService( "names.nick.openoffice.TestOOPythonCompImpl" )
print x.TestOOPyDouble ' Displays value (47.3) without a problem
y=23.7
setTestOOPythonDouble(y) ' This works, as does "print
getTestOOpythonDouble()"
x.TestOOPyDouble=y ' CAUTION: This causes OO to freeze: Only killing the
soffice process frees OO up again
End Sub
