Compiler problem with messages definitions

[relu91]

Using the current ipc schema inside the gateway causes the following complaints

Even if the message is not helping a lot I think the problem has to be found here:

gateway-addon-ipc-schema/messages/definitions.json

Lines 572 to 606 in 7cc08ec

	"form_element_property": {
	"title": "PropertyForm",
	"allOf":[
	{ "$ref": "#/definitions/form_element" },
	{
	"properties": {
	"op": {
	"oneOf": [
	{
	"type": "string",
	"enum": [
	"readproperty",
	"writeproperty",
	"observeproperty",
	"unobserveproperty"
	]
	},
	{
	"type": "array",
	"items": {
	"type": "string",
	"enum": [
	"readproperty",
	"writeproperty",
	"observeproperty",
	"unobserveproperty"
	]
	}
	}
	]
	}
	}
	}
	]
	},

Notice how the second schema does not have type property defined
