Narrative:

The weather had deteriorated and soia was longer possible; so we went in trail unexpectedly. I was delay vectoring an A321. I flashed an automated point out to toga. I saw that toga had a departure that was level at 5;000 but would want to climb. I called toga and said I'll stay at 8;000 or above with my aircraft. Toga approved this and steadied the point out. I turned the A321 to the ILS and stayed at 9;000. Toga began to climb his traffic. When I saw a F900 leave 7;000 I began to issue traffic to the A321. Separation was lost. I don't know why toga would climb his aircraft into known traffic when he had just given away 8;000 to me. I believe toga made a mistake and should be trained with techniques that will prevent a re-occurrence.
