spring mvc - Use spaces into the tab titles with liferay tabs -

i'm working spring mvc portlets , liferay tabs. i'm having problem put spaces tab title. let's want define inside jsp:

<liferay-ui:tabs names="sample tab 1, sample tab 2" refresh="false" value="${mycontrollervalue}"  > <liferay-ui:section>      <jsp:include page='/jsp/mypage1.jsp' flush="true"/>  </liferay-ui:section> <liferay-ui:section>     <jsp:include page='/jsp/mypage2.jsp' flush="true"/>  </liferay-ui:section> </liferay-ui:tabs> 

this not working @ (eventhough, it's example documentation) , problem spaces names (it works fine if use names="tab1,tab2", that's not want show in tab titles)

besides, need control tab show controller. this:

 if(whatever){  renderrequest.setattribute("mycontrollervalue", "sample tab 1");  } 

and causes problem, because need show tab names in several languages, i'd need pass tab want in locale language match jsp id. best thing split title tab id , use tabvalues param, no idea how it...

i read redefine languages-ext.properties, import tab,

<%@taglib prefix="liferay-ui"   uri="http://liferay.com/tld/ui" %> 

so don't have properties file, , no clue how solve it.

i'd appreciate kind of issue.

thanks in advance!

07:26:12,297 error [portletlocalserviceimpl:542] com.liferay.portal.kernel.xml.documentexception: error on line 20 of document  : cvc-complex-type.2.4.a: invalid content found starting element 'resource-bundle'. 1 of '{"http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":portlet-info, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":portlet-preferences, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":security-role-ref, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":supported-processing-event, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":supported-publishing-event, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":supported-public-render-parameter, "http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd":container-runtime-option}' expected.  

and portlet.xml file:

<portlet-app version="2.0" xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd"> <portlet>     <portlet-name>myapp</portlet-name>     <display-name>myapp</display-name>     <portlet-class>org.springframework.web.portlet.dispatcherportlet</portlet-class>     <init-param>         <name>contextconfiglocation</name>         <value>/web-inf/portlet/myapp-portlet.xml</value>     </init-param>                            <expiration-cache>0</expiration-cache>     <supports>         <mime-type>text/html</mime-type>         <portlet-mode>view</portlet-mode>     </supports>     <supported-locale>gl_es</supported-locale>     <supported-locale>es_es</supported-locale>     <resource-bundle>messages</resource-bundle>      <resource-bundle>content/language</resource-bundle>        <portlet-info>         <title>myapp</title>         <short-title>myapp</short-title>         <keywords>myapp</keywords>     </portlet-info> </portlet> </portlet-app> 

you can use language.properties have exact title names want in tab.

in <liferay-ui:tabs> can have:

<liferay-ui:tabs     names="sample-tab-1, sample-tab-2"     refresh="false"     value="${mycontrollervalue}"  > 

which nothing keys in language.properties files as:

sample-tab-1=sample tab 1 sample-tab-2=sample tab 2 

you can define language.properties file in portlet.xml as:

<portlet>     ...     ...     <resource-bundle>content/language</resource-bundle>     ... </portlet> 

and file , other language files reside in source package inside content folder, this:

docroot   |   |--> src         |         |--> content                 |--> language.properties                 |--> language_en.properties                 |--> language_ja.properties                 |--> language_de.properties                      ... 

so in controller use:

if(whatever){    renderrequest.setattribute("mycontrollervalue", "sample-tab-1"); } 

more liferay localization.
