Error type: LoadXML Description: Incorrect XML

Hi every one,
i tried to execute the samples code of Tree connector on my computer and i
have this message
Error type: LoadXML
Description: Incorrect XML

and i don’t how to fix it.
Can somebody help me please?

It seems that xml somehow is invalid, if you are using vanilla samples - most probably you have not configured db parameters, or have not imported db dump.

Try to load the same url as used for data loading in separate window of browser, it will show more detailed error info.

i have this error:
Error type: DataStructure
Description: XML refers to not existing parent
i don’t know if i have to include some xml header!

This is error can appear for tree, when data which you are loading can’t be added in the existing tree. Data xml contains at top something like

where id=“0” - id of element, to which items will be added after loading. 0 - is a default value of super-root item. In you case this value is invalid, it points to some non-existing id.
