[Building Sakai] Course Tools getting deleted

[Nkululeko Phakela]

Hi Miguel,

This makes a lot of sense. It is interesting that this would happen to a few sites, but not all of them that are using a tool that does this.

I will look into it and see if after doing the changes, the tools don't disappear. The weird part, on the local development machine, this is
never a problem, only in production.

Cheers,
Nguni

Hi Nkululeko.

Are you using any custom tool to manage sites using SiteService? How you manage this sites?

This is an idea, maybe your problem is that you are using getSites function from siteService, it returns a list of a soft version of Site objects ( Without tools and pages).

If you save this object with siteService.save, you will lose all pages and tools.

Example:

BAD:
        Map<String, String> propertyCriteria =new HashMap<String,String>();
        propertyCriteria.put("favouriteSite","true");
        
        List<Site> templateSites = siteService.getSites(SelectionType.ANY, null, templateId,
                 propertyCriteria, SortType.TITLE_ASC, null);
        Site newSite = (Site) templateSites.get(0);
        newSite.setTitle("New weird title"); <------Setting the title into a soft version of the object Site!
        siteService.save(newSite); <---- You saved the soft version, all pages and tools are lost.

GOOD:
        Map<String, String> propertyCriteria =new HashMap<String,String>();
        propertyCriteria.put("favouriteSite","true");
        
        List<Site> templateSites = siteService.getSites(SelectionType.ANY, null, templateId,
                 propertyCriteria, SortType.TITLE_ASC, null);
        Site softSite = (Site) templateSites.get(0);
        Site newSite = siteService.getSite(softSite.getId());
        newSite.setTitle("New weird title"); <------Setting the title into the object with full data!
        siteService.save(newSite); <---- Saved and everything ok.

Maybe is this problem but i don't know, its only an idea

Hope it helps, Miguel.

	Hi All, 

	We have been running into a weird problem recently. Some course sites will every now and then have all the tools in the site deleted, and so when one clicks on it, it says Site Unavailable. So then once I go into worksite setup and choose the relevant tools for the course then it appears again. However, this is a recurring problem. What could be the cause of this and what can we do to combat it?

	Any help is appreciated.

	Kind Regards,
	Nguni
