Usage of tags in freemarker paragraphs : workaround or patch freemarker ?
--------------------------------------------------------------------------
Key: MAGNOLIA-2395
URL: http://jira.magnolia.info/browse/MAGNOLIA-2395
Project: Magnolia
Issue Type: Bug
Components: core, templating
Affects Versions: 3.7
Reporter: Gregory Joseph
Assignee: Gregory Joseph
Fix For: 3.7
I encountered a bug when using tags (of the Tag sort, SimpleTags work fine) in
paragraph templates. Somehow the writer of the pageContext gets lost, and
freemarker does not like it: from {{TagTransformModel}}: {code}
if(out instanceof JspWriter) {
if(out != pageContext.getOut()) {
throw new TemplateModelException(
"out != pageContext.getOut(). Out is " +
out + " pageContext.getOut() is " +
pageContext.getOut());
}
usesAdapter = false;
} else {
out = new JspWriterAdapter(out);
// etc...
{code}
There are multiple approaches:
* currently, the include tag passes the pageContext.getOut to the paragraph
renderer. This trigger the if block above. Include tag could wrap the JspWriter
in a regular writer. This is how I fixed it with r18328
* fixing freemarker by omiting this if block - I'll contact the developers to
try and understand what the reasoning is
* figure out a way to not loose the pageContext/writer when rendering
paragraphs. I'm pretty unsure how that happens as of now.
