Now that we have the Unified Expression Language implemented in
FlexibleStringExpander, we gain the ability to use UEL functions.
On the plus side, UEL functions can make screen widget and mini-language
code more flexible and more powerful. On the minus side, you have to
know the functions and what they do (in other words, no auto-completion
when working in XML).
As an example, I frequently need to know the size of a List, Map, or
String. With current code, I have to use the bsh: prefix and a short script:
<set field="mapSize" value="${bsh:uiLabelMap.size();}" type="Integer"/>.
Using a UEL function:
<set field="mapSize" value="${util:size(uiLabelMap)}" type="Integer"/>
or to get the length of a String:
<set field="stringSize" value="${util:size(uiLabelMap.CommonParty)}"
type="Integer"/>.
I don't know if this would be of any use, or if it is desirable. I'm
just tossing the idea out there for discussion.
