Wrong setter called by jsf -

my problem is:

the first setter not second setter call, not undestand? lets go

my managed bean:

public class managedbean {      public pessoa getpersonbyparam(string a){         return hash.get(a);     }  } 

my page:

<h:inputtext value="#{mbean.getpersonbyparam(param).name}"> </h:inputtext> 

my model:

public class person {      private long id;      private string name;      // getter / setter  } 

my stack:

servlet.service() servlet faces servlet threw exception: javax.el.propertynotfoundexception:/time.xhtml @37,82 value="# {mbean.getpersonbyparam(param).name}": /time.xhtml @35,74 value="# {mbean.getpersonbyparam(param).name}": class 'br.com.diario.test.managedbean' not have property 'getpersonbyparam'. 

any idea?

from el expression can access array, hashmap , treemap. better if declare hashmap property, way can access in xhtml page. example

java code

public class managedbean {      hashmap<string, person> hash = new hashmap<string, person>();      public hashmap<string, person> gethash(){         return hash;     } } 

xhtml code

<h:inputtext value="#{mbean.hash[param].name}" />
