Question

I couldn’t find a solution for this in other posts, so here is my problem.
(In advance, I use JSF 2 with Mojarra implementation and Primefaces 3.2 on a JBoss 7.1 AS)

I am building a search-mask that should be generated dynamically during runtime. I know from another post that I should use a dataTable for that. That is what I will do.

But the search-mask consists of 3 parts, the search-criterion (e.g. name, birthday,…), the operator (is, is not, larger than, in range,…) and the operand (what the user will give as search-input).

My goal is to get the search-mask get generated dynamically, BUT the type of input field is dependent on what criterion+operator has been choosen by the user.

So if the user chose criterion: “name” and operator: “is not” from the dropdown boxes, then the input field for the operand should be just a simple p:inputText.

But if the user chose criterion “birthday” and operator: “before”, then the input field should be a datepicker like p:calendar.

My idea was to use a p:dataTable for a List of “SearchRow” objects where every object has an array of criteria and operands to use them in a h:selectOneMenu.

Then I add a valueChangeListener to the selectMenues and in there I calculate and create the right type of UIComponent I need as inputfield.

But I have no idea how to add that UICOmponent as the 3rd column inside the dataTable.

So is my idea any good and is there a way at all to solve my problem?

Thanks in advance!

Same solution as to the Problem described here. The article from @BalusC explains very nicely how to add components from the bean.
