<h1>Custom View Example</h1>
<p>
The active components of this example have been commented out. To reactivate, remove the <%-- --%> style
comment tags (but not what is between them!) and replace the view:init username and all xid attributes with valid
values.

<p>
<b>You will receive errors if you do not provide valid attribute values!</b> Read the error messages for clues about

You can create as many custom views as you want. Simply create a new JSP file in the main directory (where the
index.jsp is).

<h3>A simple table of some values</h3>
<table>
<tr>
<!--
A simplePoint tag is used to display the value of a single point.
- xid: the point to use (required)
- disabledValue: the value to display if the point is disabled (defaults to "")
- raw: whether the value should be fully rendered according to the text renderer, or should be provided in its
raw form. For example, a raw numeric is does not include a suffix, a raw multistate is its integer value,
and a raw binary is 0 or 1. (Defaults to false).
-->
<td align="right" style="padding-right:20px">A point value:</td>
<td><view:simplePoint xid="DS_337334" disabledValue="(disabled)"/></td>
</tr>
<tr>
<td align="right" style="padding-right:20px">A raw point value:</td>
<td><view:simplePoint xid="DS_301245" raw="true"/></td>
</tr>
</table>
<!--
Display charts with the chart tag. Include points in the chart with the chartPoint child tag. Most attributes should
require no explanation.
- color: this attribute can be an HTML-style hex, or any color name in the HTML specification.
-->
<h3>A chart</h3>
<view:chart duration="1" durationType="hours" width="800" height="300">

Do the point references (DS_337334, DS_301245, and DS_3011245) actually reference valid points? When i use the same code in my instance and update the references, the code works fine.

DS_3011245 was wrong it should be DS_301245.
I corrected that and now i have this error

strange isn't it
The dojo errors will go away when the other issues are corrected. Check for messages in your Tomcat console. There will likely be a message there that indicates what you should do.
For example, i got this message before i corrected the problem:

XID DS_337334 is a valid XID
I looked it up and checked it 3 times
I changed it for another xid even copy the original datasource to get a new xid.
for some reason the xid are not recognized.
The "DS" part concerns me. Are you sure you're not referencing a data source rather than a data point?
i use the name in the xid box
see image
That's a data source, Sprokkie, not a data point. Note that you are in a "data source" editing page, and there is a list of "points" at the bottom (that box with the big title that says "Points"). When the error message says that it can't find the "data point", you can assume it's probably trying to match against a data point.
that did the trick. thx
I located the datapoint it starts wit DP :)
Now it works.
now i need to find a way to use this on a remote server
Ok, good.
Just a general note that XIDs for data sources only start with "DS" by default (and the same with "DP" and data points). They can otherwise have any value as long as it is unique.
