Finally tag in Gel script

[Anon Anon]

Is there any tag in Gel script which will always get executed , even though something went wrong in Script as we have in .net and java.

 

try{

}

catch{

}

finally

{

}

in above case code written in finally is always executed even if any exception is raised or code execution is completed successfully. I want to do same thing GEL Script

We use core:catch in Gel, So is there anything for finally ???

I think the following will do it:

<!-- start of script with usual headers, etc -->
<core:catch var="err">
    <!-- do stuff -->
</core:catch>
<core:if test="${not empty(err)}">
    <!-- do stuff because an error was trapped -->
</core:if>
<!-- finally -->
<!-- the code will always run to here whether an error was trapped or not -->
    <!-- do end-of-code clean-up stuff  -->
<!-- end of script -->

 

Obviously, there's a lot more detail you will have to add.
