[TYPO3-mvc] create array as viewhelper argument

[Thomas Mammitzsch]

hi list,

i wonder if it is possible to build an argument array for a fluid 
viewhelper like link.action. Thats what i tried, but it didn't work:

<f:link.action action="myaction" controller="mycontroller" 
arguments="{mykey : myvalue}">my link</f:link.action>

regards, Thomas
