java - Inter-Portlet-Communication - Liferay -


i have problem inter-portlet-communication in liferay. 2 portlets communicating through events.

sender:

<supported-publishing-event xmlns:x='http://liferay.com'>     <qname>x:aufgabeinfo</qname> </supported-publishing-event>

listener:

<supported-processing-event xmlns:x='http://liferay.com'>     <qname>x:aufgabeinfo</qname> </supported-processing-event>

event:

<event-definition xmlns:x='http://liferay.com'>     <qname>x:aufgabeinfo</qname>     <value-type>java.lang.string</value-type> </event-definition>

sender-portlet:

<a onclick="selectedentry('${aufgabe.aufgabenname}', '${aufgabe.aufgabenid}');">    ${aufgabe.aufgabenname} </a><br/>

the onclick-event calls processaction-method via ajax call.

function selectedentry(name, id){     console.log("in click");      var url = '<portlet:actionurl name="open"/>';        $.ajax({            type: "post",            url: url,            data: {"name": name, "id": id},            datatype: "json",            success: function(){                console.log("in success");             },        });

and processaction-method setting event commincation.

qname qname = new qname("http://liferay.com", "aufgabeinfo", "x"); actionresponse.setevent(qname, jsonstring);

so listener-portlet receives event in processevent-method.

event event = request.getevent(); string jsonstring = (string) event.getvalue();

my problem need jsonstring in javascript. onclick-event doesn't refresh whole page, communication works. button refresh whole page, communication doesn't works.

any idea?

the first version of portlet specification, jsr-168/portlet1.0, did not include support inter portlet communication. second version, jsr-286/ portlet2.0, supported ipc mechanism. ipc made easy jsr-286 share data between 2 portlets. using ipc mechanisms, can share data action view phase , view-view phase.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
