calling String.replace(CharSequence, CharSequence) in title attribute yields weird result

[rosière]

Hello everyone,
I am trying to display parametrized message in <p:input> 's title attribute:

Code: Select all

  <p:inputText  ** title="#{msg['m_item_x'].replace('{0}', '1')}" >                         

The message is defined in bundle as:

Code: Select all

m_item_x=Item {0}

I would like to get a tip title as "Item 1" but I finally got "Item 10}" in my Firefox & Chrome browsers.

I also tried JSTL's fn tag:

Code: Select all

 fn:replace(msg['m_item_x'], '{0}', '1')
 

But it resulted in the same weird text.

May anyone tell me what went wrong? Thanks. Danke.

String replacement with curly braces leads to very astonishing results. To make it work you have to double-escape them. This will work

Code: Select all

	<p:inputText  title="#{ fn:replace(msg['m_item_x'], '\\{0\\}', '1') }" />

Unrelated to the solution you might want to consider to change your approach. I would de-parameterize your message (remove the {0} part) and work with simple String concatenation in the EL expression (if you are using EL 3.0+). But I know only this small fraction of your usecase, maybe you have good reasons for this.

Please note that your question is not Primefaces-related and would have been better posted at Stackexchange.

My opinion: do the replace stuff in a controller bean, not via functions
