Folks,
Can someone please elaborate on this T-4.1.3 documentary...
http://tapestry.apache.org/tapestry4.1/components/general/script.html
"Components within a Script's body may access the input and output parameters
of the Script via the OGNL expression components.scriptId.symbols.name. "
How do we assign and get a script body value to the ognl component parameter?
I have a formal parameter tableSize. I cannot perform the assignment.
HTML...
<div jwcid="[EMAIL PROTECTED]:Gallery">
<span jwcid="@RenderBody">...</span>
</div>
<span jwcid="@Script"
script="/org/trails/demo/components/Gallery.script"
theWidget="ognl:components.galleryWidget"
theTableSize="ognl:components.galleryWidget.tableSize"
/>
SCRIPT
<input-symbol key="theWidget" required="yes" />
<input-symbol key="theTableSize" required="yes" />
<let key="tableSize">${theTableSize}</let>
<body>
${numColumns} = 2;
${tableSize} = ${numColumns};
</body>
Why can't I perform assignment ${tableSize} = ${numColumns}; within the body???
It evaluates to 2_0 = 2;
Is there some BIND call on a static tapestry object I have to call formally?
All I am trying to do is see the binding thru not as an input but as an output
in order to assign the parameter/property on the actual java component.
Thanks for your help.
Best regards Ken in nashua
