Hi Jaco,
No problem! However, I suggest sending JSFT questions to the
dev_at_jsftemplating email list (I've cc'd that list) so that you can get
help from the whole team and so others can learn from your questions.
To create a component which repeats the "text" property the number of
times specified by the "count" property, you can do this in the
"template" format:
<!while #{idx}<$property{count}>
<!beforeLoop
setAttribute(key="idx" value="0");
/>
<!encode
inc(number="#{idx}" value=>$attribute{idx});
/>
"$property{text}
</while>
The same thing in the XML format:
<!DOCTYPE layoutDefinition SYSTEM "/jsftemplating/layout.dtd" >
<layoutDefinition>
<layout>
<while condition="$property{count}>#{idx}">
<event type="beforeLoop">
<handler id="setAttribute">
<input name="key" value="idx" />
<input name="value" value="0" />
</handler>
</event>
<event type="encode">
<handler id="inc">
<input name="number" value="#{idx}" />
<outputMapping outputName="value"
targetType="attribute" targetKey="idx" />
</handler>
</event>
<!-- Render the static text -->
<staticText>$property{text}</staticText>
</while>
</layout>
</layoutDefinition>
You only need to do 1 of the 2 above example. I provided them both b/c
I created the XML one based off the while.xml implementation checked
into JSFTemplating's source tree... but then decided it was too ugly :)
(it's JSFT's first format and is very verbose -- I don't recommend using
it). So I decided to convert it to the "template" format which is the
fastest and most efficient format JSFT supports. The facelets format
*should* also work, although I haven't tested it as much so there may be
some bugs.
I ran both of the above example on my machine and they both work, for
example:
<my:customComponent text="Hello World!" count="2" />
Produces:
Hello World!Hello World!
I hope this helps!
