Re: Blog tag cloud bug?

What .sln file did you use?

How did you create your package for deployment?

Re: Blog tag cloud bug?

So I guided myself with this instructions on deployment: http://www.mojoportal.com/deploymentfromwindows.aspx.

I used mojoportal.sln, renamed it and used PgSQL as my backend. I set the data layer as described in here -> www.mojoportal.com/settingadatalayerreferenceinvisualstudio.aspx   .

Re: Blog tag cloud bug?

I don't know. Never seen this error before. It looks like it would be a missing column in the data but I checked the pgsql procedure and it seems to return the right fields.

I would get a backup of your production db, restore it on your dev machine and see if you can produce the issue locally. If so then set a break point in /Controls/TagCloudControl in the CreateChildControls method. Step through the code and find where it blows up.

Hope it helps,

Joe

Re: Blog tag cloud bug?

Ok, its not the tagcloud control. I'm looking into it to see if that field is in the results. Will reply shortly.

Re: Blog tag cloud bug?

Hi,

I confirm this as a bug, the stored procedure does not have the Heading column.

I have moved away from using stored procs on pgsql except in rare cases where its needed.

To solve this look in the DBBlog.cs find the GetEntriesByCategory method. Comment out the existing implementation.

Paste this in:

StringBuilder sqlCommand = new StringBuilder();
sqlCommand.Append("SELECT * ");
sqlCommand.Append("FROM mp_blogs ");
sqlCommand.Append("WHERE ");
sqlCommand.Append("moduleid = :moduleid ");
sqlCommand.Append("AND itemid IN (SELECT itemid FROM mp_blogitemcategories WHERE categoryid = :categoryid ) ");
sqlCommand.Append("ORDER BY ");
sqlCommand.Append("startdate DESC ");
sqlCommand.Append(";");

NpgsqlParameter[] arParams = new NpgsqlParameter[2];

arParams[0] = new NpgsqlParameter("moduleid", NpgsqlTypes.NpgsqlDbType.Integer);
arParams[0].Direction = ParameterDirection.Input;
arParams[0].Value = moduleId;

arParams[1] = new NpgsqlParameter("categoryid", NpgsqlTypes.NpgsqlDbType.Integer);
arParams[1].Direction = ParameterDirection.Input;
arParams[1].Value = categoryId;

return NpgsqlHelper.ExecuteReader(
GetConnectionString(),
CommandType.Text,
sqlCommand.ToString(),
arParams); 

rebuild and redeploy the mojoPortal.Features.Data.dll

I have made the same change here to fix this for the next release.

Thanks,

Joe

Re: Blog tag cloud bug?

I'm affraid Joe that there is still problem with tag cloud. When I switch on the "Use Tag Cloud For Categories?" in blog I get an error and the page with blog can't be displayed at all.

System log for that:

Re: Blog tag cloud bug?

I don't know. I can't produce this problem here using pgsql, just tried it. I add a blog make a post with a new category and then changed to use the tag cloud and it works.

The sql statement has the needed fields but the error sounds like it does not.

I recommend get a backup of your db and step through it locally and see if you can find the cause. 

Best,

Joe

Re: Blog tag cloud bug?

So I was able to debug it. Sorry I did it so late but didn't have much time recently.

The problem seems that the itemWeight value is 10 and there are only 0 to 8 cssClasses so the expression  cssClasses[itemWeight - 1] is really cssClasses[9] so it doeasn't exist. :-/   

The exception details are below:

Hi Przemek,

Thanks for debugging this. It should now be fixed in the new release and I will have it in svn trunk by tonight.

Best,

Joe
