Jacques Le Roux commented on OFBIZ-4885:
----------------------------------------
Mmm, thinking about it I wonder ow this is handled in minilang now (after last
overhaul)... The idea is to converge at term to have only one syntax in
<actions> and minilang...
> Support for closure, if and loop for inline groovy script in set filed of
> action tag.

> URL: https://issues.apache.org/jira/browse/OFBIZ-4885
> Project: OFBiz
> Issue Type: Improvement
> Components: framework
> Affects Versions: SVN trunk
> Reporter: Amit Kumar

> Currently, we can use inline groovy script in set field tag of action tag in
> screens and forms. like
> <form>
> <action>
> <set field="tempVar" value="${groovy: someList?someList.size():0;}"/>
> </action>
> </form>
> But, we can not use closure, if or loop in this kind of inline groovy. like
> <form>
> <action>
> <set field="tempVar" value="${groovy: str='';
> someList.each{str=str+it}}"/>
> </action>
> </form>
> The reason is that matching closing } braces for any opening { braces in the
> script are ignored and script does not get compiled if it contains any set of
> { and }.
> So, I have added a patch which makes it possible to use closure, if and loop
> by handling { and } braces occurs with in the script.
