Summary: javascript updated submit button value ignored
Initial Comment:
Hi Guys,
I have a situation where I want to be able to change the
submit button value using javascript on the page.
I can do this fine however the renderComponent method
of the Submit class throws away the value that it
retrieves from the requestContext and passes through
the original value that is stored in it's _tag member.
The problem is easily solved by the following code
changes to the renderComponent method of
net.sf.tapestry.form.Submit.java
protected void renderComponent(IMarkupWriter writer,
IRequestCycle cycle)
throws RequestCycleException
{
...
String value = cycle.getRequestContext
().getParameter(_name);
// If the value isn't there, then this button wasn't
// selected.
if (value == null)
return;
if (_selectedBinding != null)
// This code ignores the actual value of the button when
//it is submitted and presumes that it will not change
// _selectedBinding.setObject(_tag);
//Suggested fix - pass through the new button value.
//rather than the original tag value
_selectedBinding.setObject(value);
if (_listener != null)
_listener.actionTriggered(this, cycle);
return;
}
...
}
If I can make any of this clearer please let me know.
Cheers,
Daniel
