Custom PDF Button

I currently have a servlet that takes the XML submitted from my XForm and uses it to generate
a PDF file. I would like to have a button that performs this action, but am having trouble understanding how to implement it. My submission currently looks like this:

<xforms:submission id="save-submission" mode="asynchronous"
action="/form/pdf" xxforms:target="_blank"
method="post" f:url-norewrite="true" replace="instance" ref="instance('fr-form-instance')">

<xxforms:script ev:event="xforms-submit">checkSubmissionStatus();</xxforms:script>
</xforms:submission>

This works well, but my PDF is not coming out. If I hit the http://localhost/app/form/pdf, the PDF is served properly. What am I missing?

Thanks in advance.

Re: Custom PDF Button

I see several possible problems:
1. Because you have f:url-norewrite="true", the XML is submitted to
http://localhost/form/pdf, not http://localhost/app/form/pdf. If servlet
is in the same webapp as Orbeon, you could just remove this attribute.
Or maybe f:url-norewrite="true" is correct, but you just forgot to add
/app in URL.
2. If you want to download that PDF after submit, you should use
replace="all" instead of replace="instance".
3. I'm not sure if mode="asynchronous" and xxforms:target="_blank" add
any value. I would just remove them to be safe. Instead I would add
xxforms:show-progress="false", so that "Loading..." message will not be
left hanging.

Re: Custom PDF Button

Tambet,

Thanks for leading me in the right direction. I had to do two things:

1) Change to replace="all".
2) Make the action URL absolute, i.e. http://localhost/form/pdf

After making those changes, it worked. :)

Is there a way where I can use a relative URL and avoid a local submission? If I change the action back to "/form/pdf", it doesn't work because it's attempting a local submission. I'm running a separate deployment with Orbeon separate from my WAR.

Re: Custom PDF Button

I was able to get it working. It turns out I wasn't setting the 'oxf.xforms.local-submission-forward' property to false.

Thanks again!

Re: Re: Custom PDF Button

Glad you figured it out! It might be worth brief investigation, why
local submission doesn't work. Do you have filters that won't be applied
with local submission? This can be easily cured with few additional
web.xml elements, see here:

Local submission performs better and you won't get errors when running
the server behind https proxy with untrusted SSL certificate.
