Dennis Hamilton commented on OFFICE-3494:
-----------------------------------------
Help me out here. I don't understand this example:
""""
For example, if we have table:base-cell-address='A1' then the condition is-true-formula(A1+C23=42) is equivalent to a proposed is-true-formula(CURRENTVALUE()+C23=42).
"""
Suppose I have, as a child of <office:spreadsheet> <table:content-validations> the following:
<table:content-validation
table:name="+C23=42"
table:base-cell-address="A1"
table:condition="is-true-formula([.A1]+.[.$C$23]=42"
/>
And there are these three cells:
<!-- This is cell [$'Sheet 1'.$A$1] -->
<table:table-cell
table:content-validation-name="+C23=42"
office:value-type="float"
office:value="17"
>
<!-- This is cell [$'Sheet 1'.$X$12] -->
<table:table-cell
table:content-validation-name="+C23=42"
office:value-type="float"
office:value="-1.5"
>
<!-- This is cell [$'Sheet X'.$BB$11]
<table:table-cell
table:content-validation-name="+C23=42"
office:value-type="float"
office:value="0.05E-6"
>
How are all of these the same as if I had used
table:condition="is-true-formula(CURRENTVALUE()+.[.$C$23]=42"
instead?

> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: Sub-task
> Components: Needs Discussion, OpenFormula, Part 2 (Formulas)
> Affects Versions: ODF 1.2 CD 05

> The CURRENTVALUE( ) function is an additional Information Function that provides access to the existing value in the context for which the OpenFormula formula is being evaluated.
> This function corresponds to the current-content( ) function defined in ODF 1.2 style:condition and table:condition attributes and it has the same purpose:
> Whenever the evaluation is in a context where there is a current value, that value is made available to the evaluation as the result of CURRENTVALUE( ). [Note: a current value need not be associated with a specific cell or even a table, depending on the context in which the evaluation is employed.]
> Whenever the current value is that of a table cell, that value is delivered in the same manner as if CURRENTVALUE( ) were a reference to that cell.
> CURRENTVALUE( ) is a special form of reference that delivers a value based on the context of evaluation.
> When there is no current value available, CURRENTVALUE( ) returns an error-type value. If the current value is an error-type value, that error is returned.
> Evaluation of CURRENTVALUE( ) shall not induce recalculation. It does not constitute a recursive reference of any kind.
