JET tag to set local variable - Flag [message #51950]

Hi,
I need to set a local variable - like boolean flag in my template file for
a business logic condition that should occur only the first time .(flag
before iteration begins) .
I did not find JET tag to set local variable. c:set tag sets XPath
expression only.
Part of snippet is below:
<c:setVariable select="$oldSpringContext/beans" var="beanRoot"/>
<c:iterate select="$currentArtifact/package" var="currentPackage">
<c:iterate select="$currentPackage/class" var="currentClass">
Pls let me know if JET tag exists or workaround.
Regards,
Justin.

Justin:

Boolean, string and numeric expressions are also valid XPath expressions.

So:

<c:setVariable var="firstTime" select="true()"/>
<c:iterate ... >
<c:if test="$firstTime">
<c:setVariable var="firstTime" select="false()"/>
... first time processing...
</c:if>
</c:iterate>

FYI. You can also do:

<c:setVarible var="i" select=" 1 "/> <%-- $i equals the number 1 --%>

or

<c:setVariable var="ECLIPSE" select=" 'org.eclipse' "/> <%-- $ECLIPSE
equals the string 'org.eclipse' (without the quotes) --%>
