Enabling Disabling

["Savantraj, Chennamakal Subramanian" <Sa...@ap.sony.com>]

Hi,

Pls share with me if anybody implemented the following concept.
	
	1. Enable and Disable HTML controls based on some control flags on
FormBean.
	2. Not by using disabled attribute in each custom tag.
	3. Idea is to prevent Decision making statements in JSP pages. Also
want to handle some complex logics to decide enabling and disabling(For
Example, using same form for Enquiry,Edit,Insert operations and make
controls enabled or disabled based on the operation)

Pls provide me with your expert opinion.
Best Rgds

Your "disabled" attribute in each tag can reference an array entry of an array
of booleans, one for each "operation type".  These values will be set in your
action, not in the jsp page.  There is no "decision making" in the JSP page.
Use Struts-EL to make the variable references cleaner.
