I have been away from Struts 2 for many months and was prompted with this
question yesterday:
Why does this code throw a null pointer exception?
<s:url action="employeeAction_subsetByDepartment">
<s:param id="department" value="%{#attr.currRow.department}"/>
</s:url>
After jacking around with it for nearly an hour I realized that id should be
name! It seems the adjoining tags were using the id attribute and this
developer had applied common sense and used id here as well. Now I realize
the JSTL/OGNL debate has caused much consternation among developers and I
have sort of gotten over that whole mess. But this tipped my scale! What
gives with the Struts 2 tag library? Seriously, step outside yourself and
think about it before you answer. Is this a wart on the framework?
Peace,
Scott
