=========================================
REPORT BUILDER
When trying to insert (apparently any) function in report control (text box) via Function Wizard, LO crashes.
Comment 1 Buovjaga 2018-03-18 14:23:06 UTC 
Ok, I did Insert - Report controls - Text box, what do I do next?

Comment 4 c18florentino 2018-03-19 12:55:31 UTC 
Try inserting (apparently any) function from thw wizard -- e.g. into a conditional formatting.
When Next pressed Base crashes.

How do I get this?
Comment 6 c18florentino 2018-03-19 14:29:55 UTC 
Say you have field1 and desires to have report line (detail section) of field2 printed only IF field1 IS NOT NULL.
How do you do it in Report Builder?
Comment 7 c18florentino 2018-03-19 14:34:24 UTC 
CONDITIONAL FORMATTING >
=NOT(IS BLANK(field1))

But note that apparently this happens with any function in the expression builder.
And only in 6.x
I've never noted this in previous versios of LO Base.

Comment 13 c18florentino 2018-03-19 17:23:20 UTC 
Build a query (I think it could be just 1 field);
build a report on the query;
try to add a function (e.g. as I've exemplified above) in the field's datasource ("formula or field" property).
Best yet: check the report error and o you should be able to check the log.
I am not (able to do so)...
Comment 14 c18florentino 2018-03-19 17:31:07 UTC 
SELECT field1, field2 FROM your_table;
REPORT DESIGNER ADD >> field1 filed2
Let's say you want a conditional formatting so to field2 just gets printed (in report's detail) if field1 IS NOT NULL

But take notice that this is just an example. It appears that the proplem is with ANY function in the wizard.
So, I think best is not to fous on a particular example but to look into the log as it shows that the problem happened and where in the code.
Comment 15 Buovjaga 2018-03-19 18:01:48 UTC 
Ok, I can repro.

Steps:

1. Open any database, for example attachment 140158 [details]
2. Click Reports - Create report in design view
3. Insert - Report controls - Text box
4. In the Data deck of the sidebar, click the "..." next to "Data field"
5. Double-click any function

In the example DB let's say want to conditional format field txt on
ISEVEN(ID)
txt > Properties > CF >
1. Select ISEVEN conditional [before crash in example DB]
2. Next (to insert the function) [crash with no recovery]
Absolute crash with no immediate recovery. Needed to call Task Manager >
End Task LO
before recovery of .odb
