Backend store unavailable while edit metadata

[wangf1122]

Due to the base variable used for variety of javascript, xsl, and html

core-geonetwork/web/src/main/webapp/xslt/common/base-variables-metadata.xsl

Lines 125 to 126 in 512b1cc

	<xsl:variable name="resourceContainerDescription"
	select="util:getResourceContainerDescription($metadataInfo/uuid, ($metadataInfo/draft != 'y'))"/>

When the backend store is not available which returns an runtime exception

I attempt to putting exception try catch ignoring within the execution method

core-geonetwork/core/src/main/java/org/fao/geonet/util/XslUtil.java

Lines 634 to 639 in 512b1cc

	if (store.getResourceManagementExternalProperties() != null && store.getResourceManagementExternalProperties().isFolderEnabled()) {
	ServiceContext context = ServiceContext.get();
	return store.getResourceContainerDescription(ServiceContext.get(), metadataUuid, approved);
	} else {
	// Return an empty object which should not be used because the folder is not enabled.
	return new FilesystemStoreResourceContainer(metadataUuid, -1, null, null, null, approved);

But the page looks corrupted:

It would be nice feature to develop to have metadata editing available even though the backend store is not available
