Complex table indexes not working in Ipad

Hello All,

         I have set parent indexes for complex table drop down,when searching with these indexes in windows platform it is working fine but when the same application is checked in ipad with the same indexes,the search criteria is not returning the records even they exists in complex table.Data is not populating for some letters.Does it is the default behaviour or problem in setting the indexes.I have set cascade,table indexes,display field,return field.More beneficiary if any one can post the difference between cascade and table indexes.Please help me in this regard

Thanks in advance

Thanks & Regards,
