Define.xml validation fails on community version 2.2.0
Forums: Define.xml
reference to variable which does not exist.
Hi Ravish,
It looks like you have a reference to variable which does not exist.

Hi Sergiy, Thank you for…
Hi Sergiy,
Thank you for your reply. You mean some content is missing in define.xml file? Or is it just that a runtime instance is missing in the executing program?
Reference to variable which does not exist
I tested the use case of referencing a variable that does not exist, i.e. an ItemRef pointing to an ItemDef by OID, but no ItemDef with that OID present.
In that case, the validation completes, and one gets an error "OD012": "Invalid root element".
If you contact me personally, I can look up why the software crashes as I do know the source code pretty well.
Reference to variable which does not exist
By looking into the source code, I could easily find out (and reproduce): SEE IMAGE BELOW:
The error is occurring at line 550 in class "ContentValidator". It occurs in the case of a "ValueList-ItemRef" pointing to an ItemDef (by OID) but the corresponding ItemDef (with that OID) is not present. In such a case, the method "itemDefs.get(itemRefOID)" returns "null", and a "null" value cannot be split of course. So this is about valuelist variable definitions.
Essentially, the software should first check whether an ItemDef is present for the given ItemRef, and if not, provide an error message. It should not crash.
The error does not occur when it is an "ItemGroupDef-ItemRef" and the ItemDef is not present. See my prior entry.
@Ravish: you can always contact me for more details and how to correct this.
Hi Jozef, You are right!!…
Hi Jozef,
You are right!!. One of the itemrefs in define.xml was missing an equivalent itemdef. That was causing the application to crash.
Thank you so much for your input. It was really helpful.

Thanks Ravish!
Can you contact me? I can take care of a software bug-fix.
I am trying to validate define.xml file. The software crashes with following bug:

Can you provide the cause of this issue?
