Java Mapping - Dynamic FileName is not getting assigned to the attachment

Hi Experts,

I am facing an issue in my java mapping . Dynamic filenames are not getting reflected while I am creating attachments in my mapping and configuring it via mail adapter .

I am getting both the attachments with the name : Attachment.txt

Following is the code that I am using ...

Attachment att1 = out.getOutputAttachments().create(

Attachment att2 = out.getOutputAttachments().create("content id1","text/plain;charset=\"UTF-8\";filename=\"def.txt\"", b1);

The above code is working perfectly on PI 7.31 EXT_04_REL .... But its not working on PI 7.31 EXT_07_REL....

Please let me know if there is any workaround...

Regards

Vinay
