Summary0010138: Crash on attempt to copy an OCAF attribute: TDataStd_RealArray, TDataStd_IntegerArray
DescriptionOn attempt to copy one of the OCAF attributes (TDataStd_RealArray or
TDataStd_IntegerArray) the application crashes. The crash happens in ::Paste()
method of the attribute calling the method ::ChangeArray(). The last mentioned
method requires some additional checkings on NULL in order to prevent the crash.
In addition, the static method Set() of these attributes doesn't process the
lower / upper limits of the keeping arrays in case of re-initialization of the
array.
Also, the method ::ChangeArray() checks the whole array for equality in order to
prevent backupping of the attribute. It seems reasonable to allow the array to
backup itself on any user request and let him manipulate the backups.
Additional information
and documentation updates		Documentation remark, added by SZY 2007-06-01 14:23:39:

New features:
To method ::ChangeArray() of TDataStd_IntegerArray, TDataStd_RealArray and
TDataStd-ExtStringArray OCAF attributes added a boolean flag <isCheckItems>
indicating comparison of each item of the input array with items of the
internal array of OCAF attribute.
If the flag is equal to true (default value), the OCAF attribute compare the
arrays and call the backup methods only if the arrays are different (the user
actually changes the arrays).
If the flag is set to false, the input array replaces the internal array of OCAF
attribute without any check. The flag is applicable to the case when dimensions
of arrays are equal.
Changes:
There are several changes in the behaviour of these two OCAF attributes:
1) The method ChangeArray() modified to fix bug and to be comparible with the
previus functionality
2) Implementation of several methods: Value, Upper, Lower, Length, Dump is
changed to be more optimal.

Modified entities:
TDataStd_IntegerArray
TDataStd_RealArray
TDataStd_ExtStringArray
