if field width is set to 255(type :string),after edit vertices and save changes in arcgis,fields created after this field will have error value in arcgis attribute table

[cjzsmgdal]

field was created :

OGRFieldDefn oField36("FileStamp",OFTString);
	oField36.SetWidth(254);
	if( poLayer->CreateField( &oField36 ) != OGRERR_NONE )
		return false;
	OGRFieldDefn oFieldAd8("OutPtAd8",OFTString);
	oFieldAd8.SetWidth(254);
	if( poLayer->CreateField( &oFieldAd8 ) != OGRERR_NONE )
		return false;
	OGRFieldDefn oFieldNodePtX("NodePtX",OFTReal);
	oFieldNodePtX.SetPrecision(3);
	if( poLayer->CreateField( &oFieldNodePtX ) != OGRERR_NONE )
		return false;
	OGRFieldDefn oFieldNodePtY("NodePtY",OFTReal);
	oFieldNodePtY.SetPrecision(3);
	if( poLayer->CreateField( &oFieldNodePtY ) != OGRERR_NONE )
		return false;

field's value of field "NodePtY" should be greater than 0, but if field "OutPtAd8" is set to width 255,after edit vertices and save changes in arcmap10.0,all feature's "NodePtY" value will be 0 field's width must be a value [0,255) ?
