Frederic Daoud closed STS-640.
------------------------------
Resolution: Duplicate
Fix Version/s: Release 1.6
Release 1.5.1
Actually, STS-591 accurately describes the problem: relative paths do not work
with layouts, and if they do, it's by coincidence and very fragile. I'll add a
warning about this so that you get an error message describing the problem if
you use a relative path in a layout-render tag.
> Relative path for layout-render tag's name attrib causes exception

> This issue occurs if running via Eclipse or straight on Tomcat. Cleaning
> build and Tomcat cache has no effect.
> Scenario 2:
> Changing overriding JSP to use absolute path:
> <stripes:layout-render name="/WEB-INF/jsp/layout/defaultlayout.jsp">
> ...........
> </stripes:layout-render>
> Solves the problem.
> Placing a breakpoint on
> net.sourceforge.stripes.tag.layout.LayoutDefinitionTag (line 70 - Stripes
> 1.5), will show that once you step over 70 & 71, that the stack variable is
> NULL in scenario 1, but is correctly created in scenario 2.
> LayoutDefinitionTag:
> 69: // Fetch the layout context containing parameters and component
> overrides
> 70: Stack<LayoutContext> stack = (Stack<LayoutContext>)
> 71: getPageContext().getRequest().getAttribute(PREFIX + name);
> 72 this.context = stack.peek();
> Evaluating the expression (PREFIX + name) in scenario 1 gives you:
> stripes.layout./WEB-INF/jsp/layout/defaultlayout.jsp
> Evaluating the expression (PREFIX + name) in scenario 2 also gives you:
> stripes.layout./WEB-INF/jsp/layout/defaultlayout.jsp
> Quite strange. The problem must be deeper...
