We are using the <struts-html:image> tag to produce graphical buttons. This tag writes
a HTML tag <input type="image" name="aaa">.
the problem with the <input type="image"> tag is that it submits "aaa.x" and "aaa.y"
parameters rather than the usual "aaa" parameter.
Thus I cannot use the <struts-html:image> for a cancel function because the
ActionServlet tests for Constants.CANCEL_PROPERTY, in a request that include only
Constants.CANCEL_PROPERTY.x and Constants.CANCEL_PROPERTY.y parameters.
So I have subclassed the ActionServlet and Action classes as below
ActionServlet (row 1851)
if (request.getParameter(Constants.CANCEL_PROPERTY) != null) {
...
MYActionServlet:
if (request.getParameter(Constants.CANCEL_PROPERTY) != null
||
request.getParameter(Constants.CANCEL_PROPERTY+".x") != null) {
...
Action (row 457)
protected boolean isCancelled(HttpServletRequest request) {
return (request.getParameter(Constants.CANCEL_PROPERTY) != null);
MYAction
protected boolean isCancelled(HttpServletRequest request) {
if (super.isCancelled(request))
return true;
return
(request.getParameter(org.apache.struts.taglib.html.Constants.CANCEL_PROPERTY+".x") !=
null);
}
Isn't there a better way to handle this problem ?
anybody else using <struts-html:image tag> to handle cancel ?
