I added an option list to an existing node to enable selecting an existing property.
The value of the property is saved as string (e.g. "address":"72") to the flow.json instead of "address":72.
Actually I copied the tags of another property and renamed the class and the id. The source property works fine and its selected value is saved as number.
Please advise how I can force the property value to be saved as number to the flow.json.
Without seeing exactly what you've done, it's hard to know why it isn't working.
What changes did you make to the nodes html file?
I changed this:
<div class="form-row"> <label for="node-config-input-address"><i class="fa fa-user"></i> Address</label> <input type="text" id="node-config-input-address" placeholder="0x48"> </div>
<div class="form-row"> <label for="node-input-address"><i class="fa fa-address"></i> Address</label> <select id="node-input-address"> <option value=72 >0x48</option> <option value=73 >0x49</option> </select> </div>
