-----------------------------------------------
Summary: Returning false in a model PostConstruct causes an
java.lang.IllegalStateException
Key: SLING-8079
URL: https://issues.apache.org/jira/browse/SLING-8079
Project: Sling
Issue Type: Bug
Affects Versions: Sling Models Impl 1.4.10
Reporter: Santiago García Pimentel
I was just trying the exporter framework and the feature from SLING-7124, where
you can return false in a post construct to prevent a model to being returned.
Unfortunately I found myself with an IllegalStateException:
{quote}java.lang.IllegalStateException: No throwable available at
org.apache.sling.models.impl.Result.getThrowable(Result.java:61) at
org.apache.sling.models.impl.ModelAdapterFactory.createModel(ModelAdapterFactory.java:263)
at
org.apache.sling.models.impl.ExportServlet$RequestAccessor.getExportedString(ExportServlet.java:202)
at org.apache.sling.models.impl.ExportServlet.doGet(ExportServlet.java:106) at
org.apache.sling.api.servlets.SlingSafeMethodsServlet.mayService(SlingSafeMethodsServlet.java:266)

org.apache.sling.api.servlets.SlingSafeMethodsServlet.service(SlingSafeMethodsServlet.java:374){quote}
It seems like the ModelAdapterFactory assumes that there should be an exception
if a model was not returned, which is no longer the case. I don't think this
exception should be thrown.
The easiest solution I think is to make o.a.s.models.impl.Result not throw that
exception and let the ModelAdapterFactory handle it, but Im not sure that would
the be most appropriate way.
