Hi,
I have recently implemented an exposer table from a collector to be viewed off a topology card in an epm system. I have implemented this in several connectors already and have not received this DIS error before. I tried looking up the error code and couldn't find details about it anywhere. Below in the image you can see the error code and that the page clearly exists above in the display tag. Anyone have any idea why this error is showing up? 
Hi Meekaeel,
The validator should ignore pages that start with "CPEIntegration_".
A task was already created for that (ID 128947)
In short:
For EPM (CPE) integrations table column parameters can be displayed as standalone parameters by defining a page name that starts with "CPEIntegration_".
This approach allows you to export specific parameters, similar to how it's done for a DVE element.
The goal is to create pages like this:
For example, to add the Number Endpoints parameter to the UI, you can use the following configuration:
<Display>
<RTDisplay>true</RTDisplay>
<Positions>
<Position>
<Page>CPEIntegration_Data/Network</Page>
<Row>1</Row>
<Column>0</Column>
</Position>
</Positions>
</Display>
For more info what is CPEIntegration pages please see the following:

Kind regards,
See my above comment to pedro, the fix was adding a standalone param IE (a title header). The validator has the wrong wording it should recommend a title not tell the user the page does not exist.
