Issue with aui:form

[Martin Phee, modificado hace 12 años.]

Having an issue with a portlet. I'm using the aui:form tag and getting this exception.

javax.el.ELException: Cannot convert http://localhost:8080/web/ula.... of type class java.lang.String to interface javax.portlet.PortletURL
at org.apache.el.lang.ELSupport.coerceToType(ELSupport.java:434)
at org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:188)

And the compiled JSP. Has anyone seem this before? I can't figure out what's going on. As best as I can tell I'm using the correct util-taglib.jar for 6.0.6.

PageContext pageContext = _jspx_page_context;
    JspWriter out = _jspx_page_context.getOut();
    //  aui:form
    com.liferay.taglib.aui.FormTag _jspx_th_aui_005fform_005f0 = (com.liferay.taglib.aui.FormTag) _005fjspx_005ftagPool_005faui_005fform_0026_005fmethod_005fclass_005faction.get(com.liferay.taglib.aui.FormTag.class);
    _jspx_th_aui_005fform_005f0.setPageContext(_jspx_page_context);
    _jspx_th_aui_005fform_005f0.setParent(null);
    // /WEB-INF/jsp/carousel/edit.jsp(17,8) name = action type = null reqTime = true required = false fragment = false deferredValue = false expectedTypeName = null deferredMethod = false methodSignature = null
    _jspx_th_aui_005fform_005f0.setAction((javax.portlet.PortletURL) org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${actionUrl}", javax.portlet.PortletURL.class, (PageContext)_jspx_page_context, null, false));
    // /WEB-INF/jsp/carousel/edit.jsp(17,8) null
    _jspx_th_aui_005fform_005f0.setDynamicAttribute(null, "class", new String("slide-form"));
    // /WEB-INF/jsp/carousel/edit.jsp(17,8) null
    _jspx_th_aui_005fform_005f0.setDynamicAttribute(null, "method", new String("POST"));
    int _jspx_eval_aui_005fform_005f0 = _jspx_th_aui_005fform_005f0.doStartTag();

Seems to be a problem with JRebel. Not sure what it is because it's only happening in one evironment.

This issue comes from com.liferay.taglib.aui.FormTag what has 2 setAction methods and no getAction methods in Liferay 6.0.6.
Now when jsp-s are compiled, the JSP compiler takes the type from last method with the name setAction from reflection. Because the method names from reflection come in a undetermined order, sometimes it finds the wrong method.
I looked into the Liferay source code and in Liferay 6.1 this bug should be fixed.

Same probleme here, but only on windows setup, on my linux there is no problem (Liferay 6.0.5).

I guess there is a possible workaround?

[Martin Phee, modificado hace 12 años.]

Yes, instead of using the string value use the object value. It should then work.

<liferay-portlet:actionURL portletConfiguration="true" var="configurationURL" varImpl="confirgurationUrl" />

Thanks, it's working!

My other workaround was to use scriplets, but I wasn't very happy about this.
