Assembling multiple XDPs having fragments - XFA Dynamic assembler failed to stitch a fragment

[manu-gupta]

HI Folks,

Wanted to check if long standing issue of fragments reference is resolved in AEM 6.5 OSGI JAVA SDK, where form is unable to stitch fragments if they are not referenced with absolute paths or are in Repo.

We have Forms and fragments placed in Network instead of Repo and we are unable to perform DDX operations as we are getting 

XFA Dynamic assembler failed to stitch a fragment

we can neither refer using absolute path nor we can place them in repo. 

We are in need to combine 2 or more XFA based forms and generate 1 combined interactive form.

Any pointers?

I will share some sample Java code

Thanks Girish, appreciate your follow up. Awaiting code snippet. FYI, i have tried creating multiple ddx but it worked for either flat or if only 1 XDP/PDF source is XFA Interactive form and rest had to be flat.

Also FYI- we already have pre-rendered Interactive PDFs which can act as source also instead of XDP. Any example around that will be helpful.

Thanks

Manu

Workflow user is my another account through which I have shared the sample Code.

you need xdp to insert another xdp
