The data shown in the table below is also displayed in my web app. With the exception of the BOOKINGNO
column, which instead has an h:commandButton
. The commandButton should only be rendered if the BOOKINGNO
record is null on the corresponding row.
At the moment, using the code below, the buttons are not rendering.
PLOTNO SITENO ACCOMNO STARTDATE ENDDATE BOOKINGNO
16 1 10 2014-10-01 2014-10-03 <null>
21 2 2 2014-09-26 2014-09-29 923291
22 2 3 2014-10-01 2014-10-03 <null>
23 2 7 2014-09-26 2014-09-29 457235
<h:dataTable>
...
<h:column>
<h:commandButton
onclick="if (!confirm('Do you want to book this holiday?')) return false"
value="Book"
action="#{dealsBean.book(item.plotNo)}"
rendered="#{dealsBean.bookingNo = null}">
</h:commandButton>
</h:column>
/<h:dataTable>
I've tried various different rendered
arguments but none seem to do what I want.
Am I getting the syntax right?
You need to use ==
as operator
rendered="#{dealsBean.bookingNo == null}"
