Prior to Spectrum release 21.2.8, you could update the Model Name with special characters like [] (). However, after 21.2.8 upgrade, the following error is thrown if these characters are included in a Model Name:
SPC-OCC-10563:An invalid model name was entered. It should match with the pattern defined.
DX NetOps Spectrum 21.2.8 or later
In Spectrum 21.2.8, a new Regular Expression filter is being used for Model naming:
TechDocs : DX NetOps 21.2.8 Spectrum : RegEx for Model Names
So in the file:
$SPECROOT/tomcat/webapps/spectrum/WEB-INF/topo/config/topo-app-config.xml
There is the following section:
<attribute-config>
<id>AttributeID.MODEL_NAME</id>
<verifier>
<class>com.aprisma.spectrum.app.swing.widget.ModelNameVerifier</class>
<param name="regex">[\p{L}\p{Digit}/.,_-]+</param>
</verifier>
</attribute-config>
The regex section in green is what you will have to add to to allow other special characters. To match a character having special meaning in regex such as
( ) [ and ]
You need to use a escape sequence prefix with a backslash (\). For example:
\. matches "."
\+ matches "+"
\( matches "("
The last three characters of the regex:
-]+
Meaning if the regex finds any of the preceding characters, anywhere in the given string, then allow it. So you would need to use the escape prefix \ before these special characters:
[\p{L}\p{Digit}/.,_\(\)\[\]-]+
