JSF and JSTL 1.2...please help, i`m going nuts

Question

Hey guys,
This is driving me up the wall. I`m running glassfish v2 b19 (i havent upgraded, because this one works for me).
But i have a problem using jstl in my jsf app. i`m trying to do the following :
                                                <c:choose>
                                                    <c:when test="#{currentRow.value['dboSTANDBY_LOG.STANDBY_LOG_TYPE'] eq 'server'}">
                                                        <webuijsf:tableColumn binding="#{standby$Standby_Log.tableColumn19}" headerText="NAME"
                                                            id="tableColumn19" sort="dboSTANDBY_LOG.SBYN_HOST_NAME" width="40">
                                                            <webuijsf:staticText binding="#{standby$Standby_Log.staticText20}" id="staticText20" text="#{currentRow.value['dboSTANDBY_LOG.SBYN_HOST_NAME']}"/>
                                                        </webuijsf:tableColumn>
                                                    </c:when>
                                                    <c:otherwise>
                                                        <webuijsf:tableColumn binding="#{standby$Standby_Log.tableColumn17}" headerText="NAME"
                                                            id="tableColumn17" sort="dboSTANDBY_LOG.APPL_SYSTEMS_PROP_INNUMBER" width="40">
                                                            <webuijsf:staticText binding="#{standby$Standby_Log.staticText18}" id="staticText18" text="#{currentRow.value['dboSTANDBY_LOG.APPL_SYSTEMS_PROP_INNUMBER']}"/>
                                                        </webuijsf:tableColumn>
                                                    </c:otherwise>
                                                </c:choose>
but the app server fails on building the page saying :
According to the TLD, the attribute test is not a deferred-value or deferred-method, but the specified value contains a #-expression
Now as far as i now, JSTL 1.2 should be included in J5EE, which is in glassfish already, correct?
and JSTL 1.2 supports using deferred expressions, correct?
So why for the love of my sanity is this not working?
aaaaaa.
Thanks

I haven't actually used/tried this myself, and I am not a JSF expert, this error looks similar to the error message attribute xxx does not support runtime expressions.
I think you are reading the error message wrong.
You have supplied a deferred expression. No question of that.
I think the error is saying that the 'test' attribute of the <c:when> tag does not support deferred evaluation. - ie you cant use #{expr} with the <c:when> tag.
According to the JSTL1.2 spec, it seems that "deferred expressions" are only supported by the looping tags (<c:forEach> and <c:forTokens>) and the <c:set> tag.
I think the JSF equivalent would be the rendered attribute. Can you use the rendered attribute with the webuijsf:tablecolumn tag? Or another JSF container type tag?
