Subject [jira] [Updated] (FREEMARKER-18) JSP EL function and custom tag with the same name owrite each other
Date Thu, 24 Mar 2016 01:05:25 GMT

     [ https://issues.apache.org/jira/browse/FREEMARKER-18?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Dekany updated FREEMARKER-18:
------------------------------------
    Description: 
If a tab library contains both a function and a custom tag with the same name, they will overwrite
each other. The one whose XML element in the TLD comes later wins (which for a valid TLD means
that the function wins). That's first and foremost a backward compatibility problem, as before
2.3.22 the custom tag always won, because the function was ignored. Starting with 2.3.22 it
can happen that you get a function instead of the custom tag, breaking an earlier working
template. Also it would be good if we can support both behavior on the same time, be implementing
both the {{TemplateMethodModelEx}} and the {{TemplateDirectiveModel}} interfaces.

This problem was originally reported here: http://stackoverflow.com/questions/36086025/custom-tags-dont-work-in-freemarker-after-updating-to-version-2-3-22/
