How to pass jelly variables between dynamic blocks

[kevinanderson]

I am in the process of updating some of our CMS pages, and I am using dynamic blocks as the core of this work.

I am using the following line to call other dynamic blocks into parent blocks:

<g:content_block type="content_block_programmatic" id="[dynamic block sys_id]"/>

I have 5 dynamic blocks that are nearly the same html format, with slightly different data. I would like combine these dynamic blocks into a   single entity and then pass the necessary data to each block in a   loop, similar to the following (this does not work):

<g:evaluate>
               /*   define data used to build navigation elements       */
               var categories = [
                       {
                               'name':'common-requests',
                               'nav_title': 'Common Requests'
                       } /* define more array entries */
             ];
   </g:evaluate>

/* loop over categories array and read up title and category name */
<j:forEach items="${categories}" var="jvar_category">   
     <g:evaluate jelly="true">   
                   var name = jelly.jvar_category.name;   
                   var title = jelly.jvar_category.nav_title;
     </g:evaluate> 

/** want to be able to access variables "name" and "title" from inside this dynamic block */
<g:content_block type="content_block_programmatic" id="e93497172bee8e00663d1c9069da15c3"/>


</j:forEach> 

This would work similar to a template in any other server-side web language...but I am unable to figure out how to pass the data I have between these two dynamic blocks.

Thanks for the help

Re: Re: Dynamic Content Block Values

Solution was to transition the child dynamic block to a UI macro:

UI Macro:   test_ui_macro1

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

       <div style="color: red;">${jvar_param1} </div>

</j:jelly>

Dynamic block   parent_block

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

       <j:set var="jvar_variable1" value="This is a sample macro variable."/>

       <g:macro_invoke macro="test_ui_macro1" param1="${jvar_variable1}" />

</j:jelly>

The session can also be used to pass data between dynamic blocks.   I am calling a child dynamic block from a parent dynamic block, and I cant use a macro b/c I need the two -phase component available in a dynamic block.

http://wiki.servicenow.com/index.php?title=GlideSession#gsc.tab=0

in the parent dynmaic block:

<g:evaluate jelly="true">

    var session = gs.getSession();

    session.putClientData('my-session-data1', jelly.jvar_ritm_sysid);

</g:evaluate>

and in the child dynamic block

<g:evaluate var="jvar_ritm_sysid">

            var session = gs.getSession();

            var ritm_sysid = session.getClientData('my-session-data1');

ritm_sysid;

      </g:evaluate>

I define the variable in the layout as a global variable so its shared. You can also pass it via a function call, but each function would need to have a unique name, or store/update it in a hidden input element, and retrieve the value from the form element

Lazy way: Declare the jelly var in the layout.
Not-Lazy way: Pass it to unique functions, between the two, or do the form element update.
