I wonder if it is possible to give clues to IDEA about how to validate/handle custom tags.
We've made a custom JSF tag library, with some of the tags defining variables in the page context (indexes for example), and as IDEA doesn't know those tags, it currently highlights references to those in el expressions as "undefined".
I've tried to look if JSF had any way for tag library creators to give hints to tools but couldn't find anything.
Has anyone encountered this problem already ? have you found a solution to it ?
