<![CDATA[condition]]> in BPMN

BPMN & Modeling Discussion & Questions
1

Hi,

On my bpmn, I got an exclusiveGateway with two sequenceFlow :

bpmn.sequenceFlow.PNG948×103 12.5 KB

One sequenceFlow contain CDATA, if I remove it, the camunda modeler doesn’t show properties of any element in diagram

The other sequenceFlow doesn’t contain CDATA but it’s working fine (I can add CDATA too without error)

I would like to know if it’s normal behavior and if the answers is yes, how to know when CDATA is required?

Thanks.
Romain.

CDATA is required for the first expression, because of the ‘<’. The CDATA protects the content.
Otherwise you would have to use < instead of the < character.
So the second expression does not need it. Although it would not harm.

thanks for answer
However I don’t understand the sentence :

Otherwise you would have to use < instead of the < character.

(maybe because of my english :blush: )

note : when I talk about CDATA, I talk about all the marker “<![CDATA[condition]]” (can’t write marker on the forum)

I wrote “Otherwise you would have to use & l t ; instead of the < character.” without the spaces between the letters. Obviously this got automatically replaced.
Meening the html entity instead of the character. See https://www.w3schools.com/html/html_entities.asp e.g.

Hi,

honestly I don’t understand why <![CDATA[condition]]> is needing. For me, both expressions are same but I will let the modeler make his work.

Thanks for your time and the link, I didn’t know about this possibilitie for writing marker like this.
