java - JSF Action is not called -


Once again I have a problem that I can not solve.

A Managed Been

@ Named (Value = "Change Infobia") @ Request Public Category ChangeInfoBean {Private String Email; Private string first name; Personal string last name; / ** ChangeInfoBean * / Public ChangeInfoBean () creates a new example {FacesContext reference = FacesContext.getCurrentInstance (); // User who is currently logged in LoginBean Bean = (Login) context.getExternalContext (). GetSessionMap () Get ("loginBean"); BasicUser user = bean.getUser (); This.email = user.getEmail (); This.firstName = user.getFirstName (); This.lastName = user.getLlastName (); } Public string changeName () {session session = HibernateUtil.getSessionFactory (). OpenSession (); Try {transaction tx = session.beginTransaction (); BasicUser updateUser = (BasicUser) session.load (BasicUser.class, this.email); UpdateUser.setFirstName (firstName); UpdateUser.setLastName (lastName); Tx.commit (); } Hold (exception e) {e.printStackTrace (); } Finally {session.close (); Return "succes"; }}

The return "success" is back to part of a page that uses bean 

   Last name: & lt; H: Input Text id = "Last name" value = "# {changeInfoBean.lastName}" /> & Lt; F: aspect names = "footer" & gt; & Lt; H: Panel Group style = "display: block; text-line: center" & gt; & Lt; H: command button value = "submit name" action = "# {changeInfoBean.changeName}" /> & Lt; / H: panelGroup & gt; & Lt; / Ch: Aspect & gt; & Lt; / H: panelGrid & gt; & Lt; / H: form & gt; & Lt; / H: panelGroup & gt; I have examined that it runs all life cycle phase, tried to remove the Bean session and tried to set it immediately = "right". I tried to delete the input text field and left the command button only. In every case the law is not called changeName (). What can be done?   
 
 
 Obviously not equal to  # {param.change}   "Name"  is done due to not submitting the form  h: panelGroup , which in turn did not implement the action of the button. 
 
 Add the following for your form: 
 
  & lt; Input type = "hidden" name = "change" value = "# {param.change}" /> gt;  
 
 This will maintain the  # {param.change}  for subsequent requests. Placing bean in the scope of the session will only work when it comes to  # {sessionBean.change} .

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
