I just had a little surprise in a Webapp, where I'm using EL in .jsp pages.
I added a boolean property and scratched my head because I had named a boolean "isDynamic", so I could write this:
<c:if test="${page.isDynamic}">
...
</c:if>
Which I find easier to read than:
<c:if test="${page.dynamic}">
...
</c:if>
However the .jsp failed to compile, with the error:
javax.el.PropertyNotFoundException: Property 'isDynamic' not found on type com...
I turns out my IDE (and it took me some time to notice it), when generating the getter, had generated a method called:
isDynamic()
instead of:
getIsDynamic()
Once I manually replaced isDynamic() by getIsDynamic() everything was working fine.
So I've got really two questions here:
is it bad to start a boolean property's name with "is"?
wether it is bad or not, didn't IntelliJ made a mistake here by auto-generating a method named isDynamic instead of getIsDynamic?
