GenericEntityException on ftl

[Sayoke Shome <sa...@TechMahindra.com>]

Hi,

I am getting GenericEntityException on Ftl pages some times if the
server is slow (When server response is fast, then it is not coming).
Actually getComponentProduct(int listIndex) of ConfigOption is throwing
this Exception. From the stack trace it does not seem to be a "could not
find relation " or "relation is not of type one or one-non fk" type. 

Can you tell me what other exceptions may come under these circumstances
and for which. 

 

More than this I want to know how to show user friendly message when
these type rare Exception comes on Ftl page. Is there any mechanism to
show some message to user to press refresh or log on later to avoid this
temporary problem (on the fly) ?

 

 

Thanks and regards,

As much as I hate to say it, I'm not sure any of us can help without  
more information, like the stack trace or at least well chosen  
selection from the original caused by exception that caused this, or  
at least the message you're getting in the top level exception.

In this case you have a Java file, that if I remember right based on  
some inside knowledge of what I'm guessing you're working on, is very  
highly customized for your app. The thing to do is catch the  
exception in your Java code, and then based on whatever analysis of  
that exception your code can do and what your requirements are for  
the user message, translate from one to the other and carry on to the  
groovy end.
