It seems impossible to link to another Page/Controller/Action/Plugin with f:link.action inside a f:form.

Test-Template:

<f:form controller="Mycontroller" action="myaction" name="newObject" object="{newObject}">
    <!-- if we don't use a property of newObject the error is not triggered -->
    <f:form.textbox property="foo" />

    <f:form.submit name="mySubmit" value="Submit" />

    <!-- adding a link.action inside form with an Object triggers an "hmac could not be verified" error -->
    <!-- for some reason 'action' is dropped in RequestHashService->generateRequestHash() -->
    <!-- this happens only when we use a property of newObject -->
    <f:if condition="true">
            <f:link.action action="baz" pluginName="pi3" controller="foobar" pageUid="14">Jetzt anschliessen</f:link.action>
    </f:if>
</f:form>

Probably that's due to the fact that the Plugin (pix) seems not to be taken into account, when generating the hmac/Requesthash?
