one component to another data transfer via valuebinding

Hello

in one component based on UIData that iterate some array itam variable is "elem"

so if i use <ui:staticText text="#{elem}"/> all work

next i write another custom component that uses value bindings with tag attribute requestId="#{elem}" and it does not work

in setProperties(...) i use this code:

requestId_=FacesContext.getCurrentInstance().getApplication().createValueBinding(requestId).getValue(FacesContext.getCurrentInstance()).toString();

there are NUll pointer exception here.

Is anybody know where is problem?

Comment:

to understand what i mean:

does not work (problem at requestId attribute):

<my:forEach items="#{page.items}" item="elem">

<my:getData jndiname="ejb/some" methodname="getValueById" requestId="#{elem}" valueStrore="objectvalue">

<ui:staticText text="#{objectvalue}"/>

</my:getData>

</my:forEach>

work well and show ids:

<my:forEach items="#{page.items}" item="elem">

<ui:staticText text="#{elems}"/>

</my:forEach>

work well and show object:

<my:getData jndiname="ejb/some" methodname="getValueById" requestId="#{page.elemid}" valueStrore="objectvalue">

<ui:staticText text="#{objectvalue}"/>

</my:getData>
