ADF table -Achieve case insensitive sort for af:column

 In Oracle ADF when we use sortable="true" on af:column By default sorting will be done case-sensitively ,which means that upper case data will be shown first and then lower case data will shown .As shown in below screenshot

,

To make this work case insensitively , we can use sortStrength="Primary" attribute on af:column as below

Now my work works case insenstive as below.

Please note this works only with 11.1.1.7 and above version
