How to write the condition for checking two or more expressions to iterate?

Option when inside iterate registered only one equals everything works
<enablement>
<with variable="accessRights">
<iterate ifEmpty="false" operator="or">
<equals value="viewer"/>
</iterate>
</with>
</enablement>

but worth only add one more condition, the test fails
<enablement>
<with variable="accessRights">
<iterate ifEmpty="false" operator="or">
<equals value="viewer"/>
<equals value="editor"/>
</iterate>
</with>
</enablement>

operator="or" applies to how the values of each iteration are combined.
The iterate children are combined using "and", so you would need to
add <or> around your 2 equals.

so this is not working

<with variable="accessRights">
<iterate ifEmpty="false" operator="or">
<or>
<equals value="viewer"/>
</or>

<or>
<equals value="editor"/>
</or>

</iterate>
</with>

Could you show your variant?

That's ANDing 2 ORs. you want to OR 2 EQUALS:

<with variable="accessRights">
<iterate ifEmpty="false" operator="or">
<or>
<equals value="viewer"/>
<equals value="editor"/>
</or>
</iterate>
</with>

This expression says if ANY item in the collection is either a viewer or
editor.

Remove the operator="or" if you want: if ALL items in the collection are
either a viewer or editor.
