Thanks for the reply Howard...
I thought it would be something like that, but I didn't want to mess
with Javascript.
Nevertheless, I've almost got it working (after some studying of
Palette...) - but I have a problem.
In my render() method, I'm doing:
symbols.put("hiddenComponent", getComponent("selectedDay"));
...
and in my MiniCalendar.script file, I've got:
<let key="hiddenName">
<insert property-path="hiddenComponent.name"/>
</let>
<let key="hiddenPath">
<insert property-path="formPath"/>.<insert property-path="hiddenName"/>
</let>
and
<body>
function <insert property-path="function"/>(var val) {
<insert property-path="hiddenPath">.value = val;
...
}
</body>
But it doesn't work. It seems that my selectedDay component is not
getting a name, because this is what I get in the rendered page:
document.Form0..value = val;
Notice the hiddenName missing. I can't get it in there.
Because I need to dynamically get the function name (like Palette does
for the select/deselect buttons), I load the script like Palette. This
means I can't bind the component using the SubmitScript example...
Any suggestions?
Thanks
