java - Primefaces dynamic columns, programatically -

i'm in process of rewriting (very) big , old richfaces application using primefaces. have situation 2 lists, 1 column names , 1 objects should represented rows.

the object looks this:

public class averygenericthingthatidonotlike {     object[] values;     //other parameters dont care } 

when should display want map values[0] first column, values[1] second , forth.

i have looked @ primefaces showcase , there example of dynamic columns have tried , can not work when not know columns can exist. reason not know columns decided database holds row saying columns should exist , can change, can not build class have columns available in showcase example.

can give me pointers here? i've been stuck on few days , need help.

edit: kinda working solution laabidi raissi. problem columns want have buttons being rendered , command links. approach able strings , if try return objects commandbuttons print java object hash.

any ideas on this?

if using jsf2, think solution may work you. first, in managed bean, build list of columns (dynamically) db, , then:

<p:columns value="#{yourmanagedbean.listofcolumnsfromdb}"  var="column" columnindexvar="colindex">     <f:facet name="header"> #{column}</f:facet>   <h:outputtext value="#{yourmanagedbean.values[colindex]}" /> </p:columns> 

edit: base on comment, think adding commandbutton or outputlink obvious (instead of outputtext):

<h:commandbutton value="#{yourmanagedbean.values[colindex]}" action="#{yourmanagedbean.someactionthattakesaparam(colindex)}" rendered="#{colindex == 4}"/> 

supposing want commandbutton in column 5.

is looking ?

hope helps
