I got the problem by the following scenario:
1.Create the seam component in conversation scope
2.in this component , i initialized a list called parametersList
3.I used window.showModalDialog() open a popup window
but i can't access this parametersList in this child page, because it is null.
i can fix it by change the component context scope to Session instead of
conversation. but i don't want to maintain so many objects in memory, is there
some ways to call the conversation objects in the popup window.
Note: the way that i open this popup window like this :
1. window.showModalDialog(baseURL.value +
"pages/cpi/Calculation_parameters_add.jsf", "",
"dialogHeight:300px;dialogWidth:500px");
2.the page structure for Calculation_parameters_add.jsp like this :
<f:view>
...
</f:view>
Can someone give me some tips about this kind of situation?
