Question

after updating to Tapestry 5.3.2, my @ActivationRequestParameter does not work anymore ..

having a form like this

<t:zone t:id="formZone" id="formZone" t:update="show">
    <form t:id="ajaxForm" t:type="form" t:zone="formZone" style="border: 2px solid #eee; padding: 15px">

        <input type="submit" id="sub" type="submit" value="Accept"/><br/><br/>

        <t:errors/>

        ${form}

    </form>
</t:zone>

trying to catch the input’s id like this

@ActivationRequestParameter("t:submit")
private String submitter;

void onSuccess() {
    logger.debug("onSuccess ," +submitter);

    if (request.isXHR()) {
        ajaxResponseRenderer.addRender(formZone);
    }
}

gives me the error

org.apache.tapestry5.runtime.ComponentEventException
Input string '["sub","sub"]' is not valid; the character '[' at position 1 is not valid.

org.apache.tapestry5.ioc.internal.OperationException
Input string '["sub","sub"]' is not valid; the character '[' at position 1 is not valid.

java.lang.IllegalArgumentException
Input string '["sub","sub"]' is not valid; the character '[' at position 1 is not valid.

Desired Behavoir

actually my goal is to be able to get submit-inputs dynamically in the form via

<t:outputraw value="buttonHtml"/> 

like

public Object getButtonHtml(){

    ContentType contentType = new ContentType("text/plain");//responseRenderer.findContentType(this);
    MarkupWriter writer = factory.newPartialMarkupWriter(contentType);


    if(isFavorite){
        writer.element("input").attribute("type", "submit").attribute("class", "sButton")
        .attribute("id", ACTION_REMOVE).attribute("value", messages.get("button_removeFavorite"));
        writer.end();
    } else {
        writer.element("input").attribute("type", "submit").attribute("class", "sButton")
        .attribute("id", ACTION_ADD).attribute("value", messages.get("button_addFavorite"));
        writer.end();
    }


    return writer.toString();
}

any hints are warmly welcome 😀

Answer 1

using the

@Inject
private Request request;
..request.getParameter("t:submit");

did the trick for me
