I'm trying to use the OGNL support in Struts 2.0.14 to set some parameter
values in the jFreeChart plugin's chart result type. But I keep getting
errors because it appears to be expecting all properties to be Strings, even
if the OGNL doesn't return a String. I'm using:
<action name="chart-frame-selection-rate"
class="com.vsp.global.controller.ChartFrameSelectionRateAction">
<param name="role">user</param>
<result type="chart">
<param
name="width">$...@com.example.config@getInt("reports","frameSelectionRate.width")}</param>
<param
name="height">$...@com.example.config@getInt("reports","frameSelectionRate.height")}</param>
</result>
<result name="failure" type="httpheader">404</result>
</action>
Where
where com.example.Config.getInt is defined as
public int getInt (String domain,String key);
But when struts tries to instantiate the result I get:
[2010-04-01 10:46:57,785] ERROR {abcOu3jlPU3Rf_9tFPSzs}

Is there any way to make struts recognize that the value is an int, so it
needs to call setWidth(int)?
