Question

So I am attempting to pass object values from a bean into a primefaces datatable (using primefaces 3.4 currently), howevever I’m facing two problems with this.

1. I cannot seem to find any way to display (or represent) a boolean value within a column in a datatable. Every time I attempt this, the table returns back totally empty (even though without the boolean column the other columns are populated with data from the bean).

2. The other bigger problem (more to do with java I think than primefaces) is that I have currently 26 different Objects I get from Siebels CRM ONDemand cloud solution, each containing their own datatypes and attribute values. I cannot for the life of me figure out how to, based on a drop down selection of a specific object display that objects fields dynamically within a primefaces datatable. So far I have just managed to display some of the fields for 1 of these objects as a sort of prototype but I am having the problem with the boolean value being display also its a nightmare.

Anybody have any sort of similar experiences ? or suggestions? I’ve been puzzled by this for over 2 weeks now and I am going absolutely crazy!

I can provide code examples or other details if needed 🙂

Thanks a lot I really appreciate any help !

Answer 1

if you want to use a h:outputText, you can set its converter to something that you implemented and inside that converter, decide about the display value.
Otherwise, if you like to view an icon according to the value,
you can do like this :

<p:column headerText="My Boolean Value">
   <p:graphicImage value="/resources/images/tick.png" rendered="#{MODEL.boolean}"/>
   <p:graphicImage value="/resources/images/red-cross.png"  rendered="#{not MODEL.boolean}"/>
</p:column>

I hope this is helpful 🙂
