Facility Control

I've read the Dashboard CustomPanel Development Guide and been through some of the Dashboard U tutorial videos. I've built most of what I need in Dashboard, but am stuck on this.

What I can't figure out is how to add new STRUCT to the STRUCT_ARRAY programmatically. I'm reading a TCP client using a listener and processing that input, and am executing plenty of other ogscript based on input from that listener.

So I have STRUCT and STRUCT_ARRAY params:

<param constrainttype="STRUCT" name="Race Definition" oid="raceDefinition" structtype="raceInfo" type="STRUCT" widget="36">
<value>
<subparam name="Race Name" suboid="name" type="STRING" value="Test"/>
<subparam name="Id" suboid="identifier" type="STRING" value="Test"/>
</value>
</param>
<param constrainttype="STRUCT" name="Race List" oid="raceList" structtype="raceInfo" templateoid="raceDefinition" type="STRUCT_ARRAY"/>

And in ogscript I know I can iterate through the structs in the struct_array - something like:

var races = params.getAllValues("raceList");
for(var index = 0; index < races.length; index++) {
ogscript.debug(races[index].name);
}

How do I create a new STRUCT, and push it into STRUCT_ARRAY?

The trick is to create a new JSON object with the structure value in it and set it to the end of the list.

The other problem you're having is that your structure is read-only so it cannot be added to. You need to add access="1" to your definition.

var structCount = params.getElementCount('raceList');

if (structCount == 1 && params.getValue('raceList.0.identifier', 0) == "") // If this is the first element and it has not been set yet
{
   structCount = 0;
}

var newValue = {
   "name": "Name " + structCount,
   "identifier": "ID " + structCount
   };

params.setValue('raceList', structCount, newValue);

Here is a more complete custom panel example that shows adding elements to a structure and then using setAllValues to reset it:

<abs contexttype="opengear" style="">
   <meta>
      <params>
         <param access="1" constrainttype="STRUCT" name="Race Definition" oid="raceDefinition" structtype="raceInfo" type="STRUCT" widget="36">
            <value>
               <subparam access="1" name="Race Name" suboid="name" type="STRING" value="Test"/>
               <subparam access="1" name="Id" suboid="identifier" type="STRING" value="Test"/>
            </value>
         </param>
         <param access="1" constrainttype="STRUCT" name="Race Definition" oid="raceList" structtype="raceInfo" templateoid="raceDefinition" type="STRUCT_ARRAY" widget="table">
            <value>
               <subparam suboid="name" value=""/>
               <subparam suboid="identifier" value=""/>
            </value>
         </param>
      </params>
   </meta>
   <param element="0" expand="true" height="308" left="17" oid="raceList" showlabel="false" top="17" width="448"/>
   <button buttontype="push" height="53" left="18" name="Add" top="337" width="297">
      <task tasktype="ogscript">var structCount = params.getElementCount('raceList');

if (structCount == 1 &amp;&amp; params.getValue('raceList.0.identifier', 0) == "") // If this is the first element and it has not been set yet
{
   structCount = 0;
}

var newValue = {
   "name": "Name " + structCount,
   "identifier": "ID " + structCount
   };

params.setValue('raceList', structCount, newValue);</task>
   </button>
   <button buttontype="push" height="54" left="318" name="Clear" top="337" width="140">
      <task tasktype="ogscript">var empty = [{"name":"", "identifier":""}];
params.setAllValues('raceList', empty);</task>
   </button>
</abs>
