Break line in dynamic values

#27010

Hi,
in our HTML we are including dynamic params (http://pd4ml.com/cookbook/pdf_dynamic_values.htm)

We need to include a breakline inside this dynamic values.
We tried with
but HTML value are escaped …

Is-there any way to include a breakline ?

Thanks

No, it is not possible due to the current PD4ML architecture specifics.

Obviously the only solution is to define a number placeholders:
$[line1]
$[line2]
and substitute them correspondingly to a needed number of lines

#29716

This is not an option for us because we don’t know the number of lines when building the HTML template

I tried another way:

My HTML template contains

$[line1]

I tried to include breakline usign the java string : n
But this fails also...

Does this means that you are also escaping "n" or did I miss something ?

#29717

A placeholder (i.e. $[line1]) substitution is performed after HTML is parsed: that means a DOM-like structure is already build.

$[line1]

code results a creation of a block element contains a single content element.

$[line1]
$[line2]

results a block element with two content elements.

A placeholder substitution is applied to the content elements.

When line1=”text 1
text 2″ dynamic data comes, in theory it should place “text 1” instead of $[line1], delete the trailing content (if any), create a new content element object, assign it to the same parent block object, put “text 2” to it, append the trailing content, deleted before. The functionality is not foreseen and not implemented.

If the situation is critical and there is no feasible workaround – we could urgently implement that on a paid basis, but I need to estimate efforts with the developers.

#29718

Yes please estimate the effort required.

To get back to my question on

: if I have

$[line1]

with

line1 = text 1ntext 2

then the HTML output should be

text 1
text 2

which is a way to display a breakline

but actually it is:

text 1 text 2

Why ? Did I miss something ?

#29719

According to our moderate estimations an implementation of the feature (+ reduced QA pass) would require 5 m/hours which would cost 400 EUR

But… I’ve just tried line1 = text 1ntext 2 – and it works (correctly breaks the line) on my workstation even without

. It is not quite clear why it works and under which conditions - I am going to investigate.


BTW: please publish a Java/JSP/etc code snippet of the way you define line1 = text 1ntext 2

#29720

dynamicParametersMap.put(“report.generation”, “ericntestnbreakline”);

#29721

It is strange, your sample also works on my side. Which PD4ML version do you currently use?

I did some more testing – even if it works on my workstation, it still renders not correctly: it does not inform its block parent element, that the new content requires more vertical space. As a result we have a broken layout. See attached.

So a proper feature implementation is still actual.

#29722

we are using version 395fx3

The option for the paid feature is something that we may afford.
Could you please give me more details on what is the function you can develop ?

#29723

As by “ericntestnbreakline” syntax there is a probability of a backslash un-escaping or misinterpreting in some environments (or in CLI), it is safer to support “eric
test
breakline” syntax. However ideally we’ll try to support both.

In this particular case the given dynamic value will be represented as three lines of text in the resulting PDF.

#29724

Support for syntax “eric
test
breakline” is nice for me

How can we proceed ?

#29725

We could start the development on Monday. If there is no pitfalls found and we are sure about the delivery time, I’ll let you know and provide you with payment options. As soon as the feature is ready, we’ll send to you a tested build by email.

#29726

Many thanks,
could you please get back to me with payment options

Thanks

#29727

We’ve just implemented a support for multi-line dynamic values.

Now
markup can be used in a dynamic value to force a line break.

I’ll send you a preview build by email to be tested on your side during our QA phase.
