Passing variable from UI Page to UI Macro

[Tommy Jensen]

I am having problems passing a varible from a UI Page to a UI Macro.

This is the UI Page

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<h1>Test</h1>
	<g:call function ="testMacro.xml" fieldName="xyz" />	
</j:jelly>

I want to pass the value "xyz" to the ui macro.

The ui macro looks like this ( I removed all unnecessary code)

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	
	<g:function test="REQUIRED" />
	
    <div style="display:none">
        <g:evaluate object="true" >
			var token = gs.getSession().getSessionToken()?gs.getSession().session.getSessionToken():gs.getSessionToken();			
		</g:evaluate>
						
		<script>		
			var value = "${jvar_test}"
		</script>
    </div>

</j:jelly>

I want the variable "value" to contain "xyz" but I cannot get this to work. I have tried all kinds of kombinations using {} or [] prefixing with jelly. etc. But the variable value is empty.

Hello Jenson,

That link is no help. Actually it has less information than the official documentation and mention nothing about what I am asking about.

I used Chuck's guidance here but it still did not work until I tried a differen variable name.

I changed fieldName to field_name and it worked.

So apparently variable names cannot contain uppper case letters. I must have overlooked that somewhere.
