Paul--
If I'm understanding your question correctly, you're just trying to
get _some_ message displayed that says that there's no data. Correct?
Assuming that, the "no data" message is rendered by the data grid's
pager which is responsible for displaying status information about the
size of the data set. In order for this to work, however, the pager
must render either:
- Automatically. By default, the pager renders before the opening
<table> tag. If the data set is empty, this is where the "no data"
message would appear.
- Manually. In order to precisely control the location of the pager,
automatic rendering is disabled by setting
<netui-data:configurePager disableDefaultPager="false"/>
In this case, the <netui-data:renderPager/> tag must be used to render
the pager somewhere inside the body of the <dataGrid> tag.
Back to the original question about changing the message, there are
a variety of ways to do this; the simplest is to add this to the body
of the <dataGrid> tag:
<netui:behavior facet="resource" name="datagrid.msg.nodata"
value="Nothing to see here."/>
This will change the behavior of the data grid by setting a new
message to display when there's no data. If you need full i18n
capability, take a look at the <dataGrid>'s resourceBundlePath
attribute, which supports creating .properties files for all messages
rendered by the grid.
Hope that helps.
