Hi smithbstl, Because I was wondering about the weird problem, I tried to reproduce your code in my SEAM application, using @DataModel and filling it after a search criteria is entered. And all works fine. Also I check what debug page returns and I get: | | class class org.jboss.seam.jsf.ListDataModel | dataModelListeners [] | rowAvailable false | rowCount 22 | rowData java.lang.IllegalArgumentException[row is unavailable] | rowIndex -1 | wrappedData [com.jtp.app.domain.User@11be57f, com.jtp.app.domain.User@114e777, com.jtp.app.domain.User@1a6c368, com.jtp.app.domain.User@e48e45, com.jtp.app.domain.User@1e64a3b, com.jtp.app.domain.User@4f7537, com.jtp.app.domain.User@7413e8, com.jtp.app.domain.User@1125fe1, com.jtp.app.domain.User@14b43d, com.jtp.app.domain.User@199c55a, com.jtp.app.domain.User@1ebf5c, com.jtp.app.domain.User@164d75, com.jtp.app.domain.User@1224b90, com.jtp.app.domain.User@52ac68, com.jtp.app.domain.User@a6a7d2, com.jtp.app.domain.User@10d0630, com.jtp.app.domain.User@e1ed5b, com.jtp.app.domain.User@1a0353d, com.jtp.app.domain.User@1a40fff, com.jtp.app.domain.User@1245e75, com.jtp.app.domain.User@3c8db9, com.jtp.app.domain.User@1823918] | toString() org.jboss.seam.jsf.ListDataModel@1cbc5cb | | As you can see in the debug the line java.lang.IllegalArgumentException[row is unavailable] is also presented for me. But nonetheless all is working fine for me. Seems like your problem is not precisely with @DataModel outjection. Maybe the problem is residing anywhere else.
