Hi,

I am trying to read an active UIMessageWrite with RWS, but it does not seem to work like it does with the rest of the UI-instructions.

I get this when I request active UI

_{_  
_“\_links”: {_  
_“base”: {_  
_“href”: “[http://10.46.231.49:80/rw/rapid/uiinstr/](http://10.46.231.49:80/rw/rapid/uiinstr/)”_  
_}_  
_},_  
_“\_embedded”: {_  
_“\_state”: [_  
_{_  
_“\_type”: “rap-uiactive-li”,_  
_“instr”: “UIMsgWrite”,_  
_“event”: “SEND”,_  
_“stack”: “RAPID/T\_ROB1/%IPM\<103\>”,_  
_“execlv”: “NORMAL”,_  
_“msg”: “”,_  
_“\_links”: {_  
_“params”: {_  
_“href”: “active/params/RAPID/T\_ROB1/%25IPM%3c103%3e?json=1”_  
_}_  
_}_  
_}_  
_]_  
_}_  
_}_

And if I use that to get active params I only get this

_{_  
_“\_links”: {_  
_“base”: {_  
_“href”: “[http://10.46.231.49:80/rw/rapid/uiinstr/active/](http://10.46.231.49:80/rw/rapid/uiinstr/active/)”_  
_}_  
_},_  
_“\_embedded”: {_  
_“\_state”: []_  
_}_  
_}_

Any help is greatly appreciated!

Best regards  
Markus
