Action on hyperlink keeps getting called when doing other actions

Question

Hello.
I have a jsf application created mostly with visual web pack, but with some custom code added. I have a table where one of the columns contains a hyperlink, which I created a custom action for. This action gets an HttpServletResponse and write urls to it with content type "audio/x-mpegurl".
Once this action has been called, any attempt to click on another link which calls this action will call the action twice. A third link click will cause it to be called three times. Any attempt to use a search button on the screen, or a table reorder link, will cause the action to be called (the number of times it was called from the last link click).
Is there some method I need to be called in order to clear something out?
Thanks in advance, and here's the code.
First the action
    public String recordingHyperlink_action() {
        try {
            String url;
            List<WarehouseQuestion> questions = null;
            Boolean isFullCase;
            isFullCase = getSessionBean1().isIsFullCall();
            log.debug("url is" + FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("url"));
            if (FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("url") == null) {
                url = null;
            } else {
                url = (String) FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("url");
            if (isFullCase && url != null) {
                if (getSessionBean1().getKludgeKeyToDetail() != null) {
                    log.debug("In hyperlink action, getting key from url: " + url);
                    WarehouseDetail wd = getSessionBean1().getKludgeKeyToDetail().get(url);
                    if (wd != null) {
                        questions = wd.getQuestions();
                    } else {
                        log.error("warehouseDetail is null in hyperlink action but want full case is true");
                } else {
                    log.error("keyToDetail is null, but want full case is true... should be no results");
            getApplicationBean1().returnRecording(questions,url,isFullCase);
        } catch (IOException ex) {
            log.error("Error in hyperlink action for playing recording", ex);
        return null;
    }Then the writing to the response.
    public void returnRecording(List<WarehouseQuestion> questions, String url, Boolean isFullCall) throws IOException {
        ExternalContext econtext = getExternalContext();
        HttpServletResponse response = (HttpServletResponse) econtext.getResponse();
        ServletOutputStream sos = null;
        FacesContext fcontext = FacesContext.getCurrentInstance();
        try {
            sos = response.getOutputStream();
            if (isFullCall == null || isFullCall == false) {
                response.setContentType("audio/x-mpegurl");
                try {
                    sos.println(url);
                } catch (IOException ex) {
                    log.error("Error adding url to response: " + url, ex);
            } else {
                response.setContentType("audio/x-mpegurl");
                if (questions != null) {
                    for (WarehouseQuestion wq : questions) {
                        try {
                            sos.println(wq.getUrl());
                        } catch (IOException ex) {
                            log.error("Error adding url to playlist: " + wq.getUrl(), ex);
                } else {
                    log.error("returning playlist, questions is NULL!");
            sos.close();
        } catch (IOException ex) {
            log.error("Error setting output stream to response: " + url, ex);
        fcontext.responseComplete();
    }Sorry for the messy code, and thanks in advance for any help, this is really driving me nuts!

How odd.. this works as intended when called from a button with a static url, but now I can't access the param in the button, which I could in the hyperlink. Here's the jsp code for the two.
<ui:tableColumn binding="#{resultsPage.tableColumn7}" headerText="Recording" id="tableColumn7" sort="questionName">
    <ui:hyperlink action="#{resultsPage.recordingHyperlink_action}" binding="#{resultsPage.recordingHyperlink}"
                  id="recordingHyperlink" immediate="true" text="#{currentRow.value['questionName']}">
        <!--<f:param name="studyNumber" value="#{currentRow.value['studyNumber']}"/>
        <f:param name="formName" value="#{currentRow.value['formName']}"/>
        <f:param name="caseNumber" value="#{currentRow.value['caseNumber']}"/>
        <f:param name="attempt" value="#{currentRow.value['attempt']}"/>
        <f:param name="date" value="#{currentRow.value['date']}"/>-->
        <f:param name="url" value="#{currentRow.value['url']}"/>
    </ui:hyperlink>
    <ui:button action="#{resultsPage.recordingHyperlink_action}" binding="#{resultsPage.playRecordingButton}" escape="false"
               id="playRecordingButton" mini="true" text="Play">
        <f:param name="url" value="#{currentRow.value['url']}"/>
    </ui:button>   
</ui:tableColumn>
