[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3428) Add a "let" seam ui tag

[Dan Allen (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-3428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12430513#action_12430513 ] 

Dan Allen commented on JBSEAM-3428:
-----------------------------------

A workaround for this is to leverage the JBoss EL.

#{eventContext.set('variableName', componentName.anyMethod())}

Granted, it is not as pretty as:

<s:let var="variableName" value="#{componentName.anyMethod()}" scope="event"/>

I do really like the idea of creating the tag. People with no sense decided somewhere along the line that variables are a bad thing that that we should do everything with our feet strapped to the floor and our hands tied around our backs. This tag would be extremely trivial to write.
