Hi,
I've created the following using the Birt-report-designer.
It should set the visibility of a Grid according to a report-parameter
<grid name="detail" id="63">
<list-property name="visibility">
<structure>
<property name="format">all</property>
<_expression_
name="valueExpr">params["ShowDetail"] == false</_expression_>
</structure>
</list-property>
[...]
how can this be created using the API???
THX
