Process Flow dynamicly shows a Process Formatter...

[DrewW]

So I needed the Process Flow formatter to show a Flow Formatter dynamically and since some of the java code was not available I updated the UI Macro "process_flow" to do what I needed. Including it all here for those who mite be interested in such an enhancement.

Add the field "u_view_condition" with a type of "conditions" to the sys_process_flow table.

Here is the new code for the UI Macro "process_flow"

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
    <link rel="stylesheet" type="text/css" href="styles/process_flow_formatter.cssx"></link>
    <tr>
        <td colspan="2" width="100%" nowrap="true">
            <div>
                <table width="100%" cellpadding="0" cellspacing="0">
                    <tr>
                        <g2:flow_formatter var="jvar_flows" table="$[__ref__.getRecordClass()]" current="$[__ref__]" />
                        <g2:evaluate var="jvar_table" jelly="true">
                            var afterCurrent = false;
                            var tableText = "";
                            var show = [];
                            var label = "";
                            var gr = new GlideRecord("sys_process_flow");
                            gr.addQuery("table", current.sys_class_name);
                            gr.orderBy("order");
                            gr.query();
                            while(gr.next()){
                                //If you do not do this you get the last value of gr.label in all elements, do not know why exactly.
                                label = new String(gr.label);
                                //Check to see if the record should be displayed.  If so add element to array.
                                //Array info
                                //   show[] -> Each element is a flow formatter record to display
                                //      show[][0] -> Label for the flow formatter to display.

Hi Drew,

I need to add the flow formatter to the Service Portal.

Do you think this will be possible?

Thanks

[SN Emy]

Hi Drew,

i added your code as you described, but when I change the state the flow didn't change I have to save first?

Thanks!

[DrewW]

All, as far as I can tell this works but the styles are off in Fuji.   Fuji also updated the formatter look all together.   I'm looking at needed changes for this to work using the new format in Fuji.   When I get done I will post it to share.

For those who are interested this has been updated over on the share site.

Hi Drew,

Please note I am looking for implementing this code in Geneva release. Is this code works with Geneva release?

Many thanks,

Gee
