Access raw expression of ValueExpression attribute to taglib component

由 泪湿孤枕 提交于 2020-01-02 06:56:11
问题 Can I access the expression string of a ValueExpression passed as attribute value to my taglib component? My goal is to programmatically derive missing attribute values from it. In this case I'm trying to avoid having to repeat an attribute as a literal. now: <a:columnText title="name" value="#{entity.name}" sortBy="entity.name" /> desired: <a:columnText title="name" value="#{entity.name}" /> -taglib.xml <tag> <tag-name>columnText</tag-name> <source>column-text.xhtml</source> <attribute>

Proper way to call servlet from Facelets?

由 徘徊边缘 提交于 2020-01-01 11:48:31

The JSF <h:form> sends by default a POST request to the URL of the current view ID and invokes by default the FacesServlet . It does not allow you to change the form action URL or method. A plain HTML <form> allows you to specify a different URL and, if necessary, also the method. The following kickoff

由 一世执手 提交于 2020-01-01 07:16:12
问题 I have a dynamic web application in Java EE with JSF, Facelets, Richfaces. My pages are all xhtml pages. So JSTL isn't working in it.
