Question :

I have assign a tag from a category which is configured with 'One tag' per object. Then, a powershell script from a colleague was launched to assign a tag from the same category. Nothing seems to happen. BTW, if I try through HTML 5 client, the Assign Tag window simply doesn't propose any tag from this category (seems logical, easy way to enforce the cardinality of the category). Afterwards, I removed the tag I manually assigned on the first step, and, now things start to be interesting: the tag that the powershell script assigned automagically appears on the the HTML 5 client. Did I misunderstand something?
