The problem

Can't set height on webview when editing a sitemap in the main UI

Expected behavior

I can set the height on a separate sitemap I edit textually and it displays fine.

Additional information

This works but isn't tall enough to display web page

Text item=DateTime label="Cameras [%1$tl:%1$tM %1$tp]" icon="camera" {
	Webview url="http://10.10.0.3:8080/static/cams.html" icon="camera"
}

When I set the height

Text item=DateTime label="Cameras [%1$tl:%1$tM %1$tp]" icon="camera" {
	Webview url="http://10.10.0.3:8080/static/cams.html" height=24 icon="camera"
}

the sitemap no longer loads and throws an error on openhab.log that starts with

2020-11-30 01:57:17.893 [ERROR] [omponents.UIComponentSitemapProvider] - Cannot build sitemap default
java.lang.ClassCastException: class java.lang.String cannot be cast to class java.lang.Integer (java.lang.String and java.lang.Integer are in module java.base of loader 'bootstrap')

This issue was moved by ghys from openhab/openhab-webui#579.

Probably the normalizeType doesn't work in this case.

openhab-core/bundles/org.openhab.core.ui/src/main/java/org/openhab/core/ui/internal/components/UIComponentSitemapProvider.java

Line 286 in 13c2d7b

widgetImpl.eSet(feature, ConfigUtil.normalizeType(value));

@ghys : it looks like similar to #1875 . MainUI is apparently converting a boolean or an integer field to a string which is not compliant with the sitemap syntax.
