Error with get-request-header in Liferay

Hi,

Actually I need to send data in the header of a request, from a form 'A' to
one 'B'. The data is sent as follows:

    <xf:submission id="test-submission"
resource="http://localhost:8080/group/bpm/test2"
                   replace="all"
                   relevant="true"
                   method="post"
                   serialization="application/xml"
                   mediatype="application/xml">
        <xf:header>
            <xf:name>myheader</xf:name>
            <xf:value>Holassss</xf:value>
        </xf:header>
    </xf:submission>
        .
        .
        .
        .
        <xf:trigger id="send-control" bind="send-bind">
                <xf:label ref="$form-resources/send/label"/>
                <xf:hint ref="$form-resources/send/hint"/>
                <xf:alert ref="$fr-resources/detail/labels/alert"/>
                <xf:send event="DOMActivate" submission="test-submission"/>
        </xf:trigger>
       

On form 'B', I try to get it in two ways:

    <xf:action event="xforms-model-construct-done">
        <xf:setvalue ref="instance('fr-form-instance')/section-1/result2"
                     value="xxf:get-request-header('myheader')"/>
    </xf:action>
       
or:
        <xf:bind id="result1-bind" ref="result1" name="result1"
                           
calculate="xxf:get-request-header('myheader')"/>


But with neither of the two ways can I access the data sent. It is necessary
to mention that the two forms are within Liferay and I have activated the
name of the header in the proxy-portlet:

        <init-param>
                <name>forward-headers</name>
                <value>myheader</value>
        </init-param>
       

I hope you can help me or have another solution, since I cannot use data
submission by URL.


Thank you!

Hi Erik,

It is another Orbeon form within Liferay, with two controls of calculated
value. I try to catch the header value in two ways with
xxf:get-request-header:

> It's another Orbeon form within Liferay

The reason I was asking os that that URL doesn't look like a Form Runner URL
or a Liferay URL.

Can you reach that URL "by hand" from your browser? What does it return?

Erik, this is form A, where the header is sent. The action is triggered from
the button:

<http://discuss.orbeon.com/file/t375629/Captura1.png>

When clicking, the button redirects to test2 and sends the header:

<http://discuss.orbeon.com/file/t375629/Captura2.png>

In the test2 form, this is where I try to catch the header in the result1
and result2 controls but I can't. In the log I can see that if it is sent:

Thanks for the clarification.

The proxy portlet doesn't support receiving POSTs at at this point (except
the internal Ajax and upload POSTs). Header forwarding should work if you
use a GET, however.
