Calling WebWork Action function with parameters from velocity template

Hello. Im stuck with a strange problem.

I have a webwork module with an action class and velocity view. I can access action class methods from velocity template with $action.getIssueTypes(). This works fine until i need to pass parameters to the method. So when i use

$action.findTransitionsByIssueTypeId($issueTypeId)

it does not call the method, but instead prints the above instruction as text on the page. I have also tried

${action.findTransitionsByIssueTypeId($issueTypeId)}

${action.findTransitionsByIssueTypeId(${issueTypeId})}

$action.findTransitionsByIssueTypeId(${issueTypeId})

${action.findTransitionsByIssueTypeId(1)}

none of above works. As soon i have anything inside parameters bracket, it seems to be treaten as simple text by velocity.

i am sure that findTransitionsByIssueTypeId is working properly. It passes the tests. I am also sure, that there is an entry with id 1.

This is what i have

atlassian-plugin.xml

		super();
		this.issueTypeManager = issueTypeManager;
		this.transitionService = transitionService;
	}

	@Override
	public String execute() throws Exception {

		return super.execute(); // returns SUCCESS
	}

	public Collection<IssueType> getIssueTypes() {
		return issueTypeManager.getIssueTypes();

	}

	public Collection<Transition> findTransitionsByIssueTypeId(final String issueTypeId) {
		Collection<Transition> transitions;
		final Long id = Long.valueOf(issueTypeId);

		transitions = transitionService.findTransitionByIssueTypeId(id);
		log.info("###" + transitions.size());
		return transitions;
	}

}

as you can see, calling $action.getIssueTypes() without parameters works fine. $action.findTransitionsByIssueTypeId($issueTypeId) does not get processed.
out of my disperation i have changed the signature of findTransitionsByIssueTypeId() to take no parameters and instead use a hardcoded id. So the call $action.findTransitionsByIssueTypeId() works.
When i touch the parameters, it does not.

Any ideas?

I've found a work around. Passing parameters as Strings and converting them to proper representation (Long in my case) seems to work.

example: $action.findTransitionsByIssueTypeId("$issueTypeId")

and in action

Long issueTypeId = Long.valueOf(issueTypeIdString);
